Designed specifically for the JK Wrangler/Unlimited, TeraFlex 9550 VSS (Vehicle Specific Shocks) Twin-Tube Shocks are engineered, valved, and tuned for extreme off-road performance while retaining a smooth highway ride.

The twin-tube design, oversized external tube with e-dipped finish, triple-chrome plated rod with oil block and seal, internal travel stop limiter, premium quality rubber bushings, and Jeep specific mounting contributes to the 9550 VSS Twin-Tube Shock’s performance, durability, and comfort.

I was using shocks from a different company and did not like the function or ride they gave. I talked wth Dennis from TeraFlex via FaceBook and he made a suggestion. I tried the shocks he suggested and they made an amazing difference.
