Upgrade those weak shock bar pins on your Jeep Wrangler JK with the JKS rear upper bar pin eliminator for bearing style shocks. Whether slow-paced rock crawling or flat-out desert racing, competition is becoming increasingly popular among Jeep owners. The demands placed on their vehicles require shock absorbers that can handle extreme conditions for sustained periods, making professional off-road racing shock absorbers a natural choice. Unfortunately, the factory Jeep shock mounts will not accommodate the special steel-on-steel, spherical bearings required for mounting.
