Super Z6 was designed by SCC for cars, trucks, and SUV's with restricted clearance around the drive tires. Based on SCC's experience with other products in the "Z" family, Super Z6 has one very special quality: it will operate in less than half of the space required by most cable chains and tire chains. Super Z6 requires only 6mm (1/4") of sidewall clearance to operate. The diagonal pattern provides constant traction, aggressive starting, stopping, cornering and ensures compatibility on vehicles equipped with traction control and electronically monitored brake systems. Traction coils, made from alloy steel are more durable than conventional tire or cable chains. A split outside cable with two fastening positions allows for easy installation without moving the vehicle, and there's no need to stop and retighten. Most cars, trucks and SUV's manufactured since the late 80's will have special clearance requirements. Don't be fooled by the appearance of the tire positioning on your vehicle. Traction products not only have to fit the tire, but must also fit within the space provided around the tires. Most issues are hidden from view as they are behind the tire near braces, suspension parts, strut housings, splash guards and fuel and brake lines. More information should be located in the owner's manual under chains, traction devices, tires or similar heading. It is important to select a traction product that is compatible with the minimum class assigned to your vehicle. The class assigned to your vehicle is based on the original tire and wheel size shown in your owner's manual. Using a different size tire may affect the chain's ability to operate properly. Some owner's manuals state that certain tire sizes do not provide enough clearnace to accommmodate winter traction products. The fact is, many of these vehicles can use SCC's Super Z6. Trying to measure the nearest obstruction under your vehicle could prove tricky.
The SCC Super Z6 SZ134 winter traction product offers superior performance for pickups and SUVs with very limited operating clearance around the drive tires. Be ready for winter driving with an innovative solution that is a step beyond traditional tire chains.
Based on the "Z" family of products, the Super Z6 is designed for vehicles with restricted clearance around the drive tires.
The Super Z6 installs quickly and easily. View installation guide.
Be prepared for driving this winter with Super Z6 traction systems.
Easy to Install
A split outside cable with two fastening positions allows for easy installation without moving the vehicle, so there's no need to stop and retighten. The traction coils are manufactured from alloy steel to increase the lifespan of the product. The Super Z6 is also designed to prevent scratching of alloy or high performance tire rims.
The Super Z6 is available to fit pickups and SUV tire sizes. It offers a unique combination of performance and convenience features for every user, including a "designed-in" rubber tightener, better all-around traction performance than conventional tire chains or cables, and greater durability.
Designed for High Performance
The Super Z6 has better compatibility with anti-lock brakes, traction control, all-wheel drive, and other electronically monitored control systems so as not to interfere with the normal handling characteristics of your vehicle. The unique design also offers a low potential for damage to vehicle body and mechanical components, even when abused.
Check the manufacturer's website for the exact product to fit your tire size. Also check your owner's manual for clearance specifications before installing winter traction products.

Z Performance for cars, pick-ups & SUVs with very limited operating clearance around the drive tires
Although its design is built based on our experience with the other products in the 'Z' family, Super Z6 has one very special quality in particular: it operates in less than half the space required by most cable and tire chains. To be more precise, it requires only 6.3 mm (1/4″) of operating space in the critical inside sidewall area of the tire (typical Class 'S' products require 15mm).
Super Z6 is available to fit passenger car, pick-up, and SUV tire sizes. It offers a unique combination of performance and convenience features for every user:
- Greater durability than conventional tire chains or cables
- Exceeds S.A.E. Class 'S' clearance requirements on vehicles with limited clearance
- Low potential for damage to vehicle body and mechanical components, even when abused

There are two broad types of traction control devices: Tire chains and traction control cables. Tire chains are actual chain links. Traction control cables are long pieces of metal cables, covered in a plastic coating, and designed to form a Z-pattern over your tires. The plastic coating is then surrounded by hundreds of tiny, round, metal springs. Cables are generally regarded as better because they are easier to install, last longer, are less damaging to roads, and work better with vehicles equipped with ABS. Also, according to SCC, you can safely drive with cable devices up to 30 mph, even on roads with no snow, without damaging them.
You should normally install traction control cables on your drive wheels, i.e. the wheels that actually push or pull your car forward. If the snow is really bad, though, you may have to install cables on all four wheels. Read your vehicle's owner's manual for more details on where to install your cables.
In any case, it's a really, really good idea to have TWO sets of cables in your car at all times. That way, if something breaks (murphy's law), you won't be stuck.
Within the traction control cable category, there are two general types of cables: Self-tensioning cables tighten themselves using a tensioner (which looks, feels, and operates like a rubber band) that you install when you put the cables on. Manual tensioning cables are tightened by you, and have to be re-tightened after you drive for a couple hundred feet or so. I've heard that emergency vehicles tend to use the manually adjustable models because they are allegedly safer at speeds above 30 MPH, but driving above 30 MPH for any non-emergency personnel is illegal with any kind of traction control device.
There are several advantages to the manually adjustable models. They tend to have more slack, which can make installation easier. Also, the tensioners (i.e. rubber bands) on self-adjusting cables can and do break (it happened to me today) and if they break, you can't use the cables. So, if you get a cable that has a tensioner, get extra tensioners, or better yet, an extra set of cables, just in case.
Here's a breakdown of SCC's cable products:
Z-Chain- Manually adjustable Traction Control Cable. Easy to install, but must be retightened shortly after you start driving. Very easy to install because they come with lots of slack. Often used by police and fire personnel.
Shur Grip Z/Super Z LT- Self adjusting cable. Tensioners can break so buy extras. Less slack, so can be harder to put on the car, but generally easier than Z-chains because you don't have to manually tighten and re-tighten them.
Super Z6/Z8- Newest Self adjusting cable, designed for vehicles with very little sidewall clearance. They have all the advantages and disadvantages of the Shur Grip Z. In addition, however, the connectors are a little harder to work with on this model because of their low profile.
The Z6 and Z8 models are SCC's latest models. They are designed to handle smaller clearances between the side of the tire and the car than their older models. As a result of that design, they are hand crimped during the manufacturing process (instead of machine crimped), and that results in a slightly higher MSRP. SCC's representative tells me that the cable size and metal springs are the same size as their other cable-based products, and so the only reason to not to get the Z6's over the older models (Super Z's) is that the Z6's are slightly more expensive (usually only a few dollars). I've noticed that the Z6 connectors are a little harder to work with than the Shur Grip/Super Z LT model.
On all of these models, the metal rings are made of a spring-like material, SCC says that you don't have to remove the chains as soon as you reach a paved road. Rather, as long as you drive under 30 MPH, SCC says that you can drive with the traction control cables on your car, even as you switch between plowed and non-plowed roads. Because each of the hundreds of little springs are separate pieces, even when one breaks, it just falls off, and the others work to fill-in the void.
The Z6/Z8 models also come with a very nice cloth bag that is sized properly to hold the cables. The older cable-based SCC models come with plastic containers that are too small to easily lay the cables in.
Installing the cables is relatively easy, and I'm definitely not a hands-on kind of guy. It took me about 15 minutes the very first time, and now that I've done it several times, I can get it done in under a minute per wheel. SCC has a video on their web-site that explains how to do it. You should always do a test-installation of cables before you need them to make sure that you purchased the correct size and know how to install it. It's also very useful to have some waterproof gloves handy and a towel with you, as it is often wet and cold when you need to install chains. A good choice for gloves are the long wristed rubber gloves that you can buy at the grocery store for washing dishes, or some disposal latex gloves. After you use the cables for the first time, fold each cable separately and then use a trash bag tie to keep each one together. Otherwise, the next time you need them, they'll all be tangled together.
Here are some hints on how to install these chains.
1. Read the instructions from the manufacturer and pay close attention to the safety instructions. The basics of the instructions are (1) stay safe, (2) position the cables correctly, (3) connect the upper rear connector, (4) connect the upper front connector, (5) connect the lower front connector, and (6) connect the black rubber bands.
The instructions are quite good, but they leave out a few helpful hints, which I will now share with you.
BEFORE YOU START, MAKE SURE YOU HAVE THE CORRECT SIDE UP! There are markings all over the cables which indicate the correct orientation. Look for them!
2. Put on some rubber dishwashing gloves and lay a towel down wherever you're going to work, or you will get very, very dirty.
3. When you slide the cables under your tires, start from a point between your front and rear tires. Slide half of the chain under your car, and then reach around from the other side of the tire to pull the cable around. Although the instructions describe a swinging slide motion, I've never seen anyone who could do that without twisting the cables up. Just pull them and things will be much easier.
4. Once the cables are around the tire, DO NOT pull the bottom connectors that hold the cables together at the bottom of the tire towards one another. Keep them as far apart as possible. If you pull them in tight, you won't be able to pull the chain high enough in the back to connect the rear upper connector, which is what you are supposed to do first.
5. When you are connecting the rear upper connector, if you can't get the rear upper connectors up above the tire so that you can see them, push the part of the cables that surround the bottom of your tire backwards and under your car a few inches. This will create slack behind the cables and allow you to pull the cables up in the back.
6. Once you have the rear upper connector connected, hooking up the front upper connector may be difficult. Try pushing the rear upper connector back so that it is laying against the inside sidewall of your tire and then pull the front upper connectors towards you as hard as you can. Don't try to pull them towards each other. While sitting, just pull them straight out, towards you, and the rest of the chains should fall into place. Then they should be easy to connect.
7. Gently pull the parts of the chain that criss-cross your tires down towards the ground so that they aren't all bunched up at the top. Look at the chain and make sure that the parts you can see, and especially the blue cable, is evenly distributed around the tire.
8. Then pull the bottom front connectors towards you (out, but not up or down) to create slack. Then connect them. Again, don't try to pull them towards one another as that makes it almost impossible to create slack.
9. On these particular cables, the upper front connector is BLACK and the bottom front connector is SILVER. When you're ready to take the cables off, if you get the wheel lined up so that the BLACK connector is on the top, it will be much easier to find and remove the rear connector (which will be opposite the black connector).
NOTE: This Amazon website does NOT correctly ID tire cable size (SZ429) as a fit for my vehicle. However, after speaking to Steve at Security Chain Co. (SCC) for the best fit, he confirmed that the SZ429 model was the right one if I wanted low profile snow cables. His verbal matched my findings through the provided SCC tire guide pdf link found within every SCC listed snow chain/cables offering here on Amazon.
I took his confirming word, ordered on a Wednesday morning for a Friday delivery using Prime 2 day shipping. Item arrived on time and off we went Friday night in our (relatively) new CRV to Sequoia NP where up to 6" of snow was expected Saturday.
I own and use SCC snow cables on my 04 Durango SLT so I know how much easier they are to put on versus standard snow chains that I used to battle with in my younger days on many different tire sizes.
This new set didn't dissapoint on use #1 that covered about 100 miles of snow/ice covered national park paved roads and not so paved back roads. They held up just fine, as expected from SCC, without any of the negative things that other reviewers claimed went wrong with their SCC purchase. Operator size purchase or installation error is what I gather affected negative opinions the most.
The installation directions could have been titled, "Snow cable installation for Dummies/Idiots" it was so straight forward. The chains were installed in about 10 minutes total on a flat, icy parking lot surface. The 2 provided rubber tensioners were just as idiot installation proof as well. Dora asks, can you follow picture instructions? You did it!
I'll be honest in stating that I did not read the cable removal instructions but that did not hinder my reverse installation process a whole lot and the chains were off in about 10 minutes (will be maybe 5 minutes next time after I read how to formally remove them).
The cables came in a little blue nylon bag with the added bonus of a window scraper (that I used instead of the smaller handled one I packed), clear plastic disposable gloves to assist with installation (I use reusable mechanic gloves), the aforementioned two rubber tensioners and the clear instructions.
I don't see the nylon bag holding up long but it's a good starter. I generally just carry the chains in one of those sturdy reusable cloth grocery bags.
I really just posted my feedback so others with my tire size know that SZ429 is a match because I could not find a confirmation here without calling SCC directly.
Happy, safe snow/ice travels to all while wearing these easy to use snow cables.
I was traveling in that inclimate weather with my wife, daughter and my niece, so my trust in another SCC product used to keep the most precious cargo safe was rewarded with a safe round trip. Thank you SCC.
I emailed Peerless chain company, and they told me they cannot recommend any set of chains for my specific car, because if the owner's manual says I cannot use chains, they do not want to transfer that liability to them. However, they mentioned that the Super Z6 chains require the least amount of side clearance of any of their chain models (6mm).
So I purchased the SZ139's (which are listed as a match for my car and the 225/55-17 tire). Turning clearance is fine, the biggest issue is how close the chains get to the strut and the brake line on the inside of the wheel. I didn't drive the car with the chains on at all - just installed them and lifted the car up to inspect them, so there's a chance the rubber tensioner would have helped pull the chains away from the brake line & strut. Who knows. I hope to never need them.
