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. Popular settings 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.


**All Delete Systems products are backed by a 2 year/30,000 mile warranty which will replace any worn out spherical bearings or broken hardware for free. *Warranty registration requires you to email us at after your package has shipped.

 ***When ordering a full set (uppers & lowers) please indicate the year range of your axle in the “notes” section.
