The ReadyLift® Hummer H3 adjustable 66-3070 torsion key provides 1.5" to 2.25" of lift and gives clearance to add up to 35" wheels and tires to the 2006-2010 Hummer H3. ReadyLift® leveling kits are the fastest, safest, least expensive way to bring the front of your vehicle level with the rear. Our torsion keys are designed to grab the "FLAT" of the torsion bar for a tighter, sturdier fit. CNC machined adjuster bolt pockets and 10.9 grade metric hardware allow for proper bolt seating, ensuring an accurate and safe adjustment.
Only ReadyLift® torsion keys are forged, making them 25% stronger than OEM and designed to last the life of your vehicle.
