The Race Series kits feature a split-tapered bushing which expands as preload is added to the assembly ensuring a precise fit. The customer is able to trim the top flange of the bushing based on needs of caster/camber with instructions on trimming.

Off-road rigs generally benefit from a 3 degree bushing to gain negative camber while lifted rigs also benefit in that they can gain back the positive caster lost when lifting. The 1.5 degree bushing option is available for more “stock” applications. 0 Degree would be no change, with no ability to customize camber or castor. 

Popular settings for offroad rigs are are -3* camber (mostly used in Ultra4 style builds), -1.5* camber/+1.5* caster, -1* camber/+2* caster, and -.5* camber/+2.5* caster

Stock lower balljoints see less failures, but are susceptible to “push out.” This happens when a shaft breaks and pushes the joint out the bottom of the knuckle. The lower system uses the same basic design as the upper, with a steel cone to match the tapered hole in the knuckle. The cup is able to be welded on both sides preventing a push-out from either direction.
