Over time the Springs that preload the King Pin Bushings and lower bearings lose their tension resulting in vertical play in the knuckles. This can cause premature wear of King Pin components and death wobble after hitting a bump which is exaggerated with large tires. The cure to this is our King Pin Spring Eliminator System! We replace the spring with a massive grease able 1" Set Screw that preloads the King Pin Bushings and Bearings. The result is a bullet-proof design with predictable handling characteristics.
This cap is a prefect addition to our Dana 60 Crossover Arm If you are not planning on running HI-Steer.
