This is our universal heavy duty crossover steering kit with our super strong 7/8" heat treated chromoly heims. This kit requires cutting the DOM tubing to length and welding in the threaded tube inserts to match your particular application. The heim joints feature a 7/8" threaded shank, and with the use of the misalignment spacers, 3/4" hardware will be used to attach the joints to the knuckles and pitman arm.
