Premium MOOG components (right) provide the same spring rate performance as the original equipment design (left)

Triple Piston Rod Seal for Added Protection

  • Outer Wiper Seal--cleans the piston rod, preventing contaminants from entering the strut and damaging the main seal
  • Main Seal--with one-piece molded design features twin seal lips, optimizing sealing performance and durability
  • Inner PTFE Buffer Seal--absorbs high pressure fluid spikes caused by rough road impact, improving the efficiency of the main seal, resulting in longer seal life. Also reduces friction, for improved ride
Spring Top Plate

Tested to one million cycles under extreme load. Ensures smoother operation, optimal performance and an extended lifetime.

MOOG Jounce Bumper

Molded from micro-cellular polyurethane. Absorbs harsh, damaging road impact and noise, for quieter driving.


Engineered for long-term, consistent performance. Premium coating for optimal corrosion resistance.

Nitrogen Gas Charged

Reduces cavitation and improves valve response and efficiency, resulting in optimal control and better ride characteristics.

Piston Rod

Highly polished, hard-chrome finish for enhanced seal function and improved durability.

Piston Band

One-piece, over-molded PTFE piston band contributes to a quieter, smoother ride.


Precision valving provides optimum driving performance combined with outstanding ride control.

Hydraulic Oil

Low-friction, low-viscosity fluid withstands a wide range of temperatures, providing consistent performance in all conditions.

Includes OE replacement hardware for many applications
Robust Brackets/ Attachment Points

Reinforced to further enhance component integrity and durability.


Many MOOG complete strut assemblies include lower mounting hardware such as strut mount bolts or pinch bolts. This supplied hardware meets or exceeds OE specification, and combined with the MOOG complete strut assembly, provides ease of installation and a thorough repair.
