*HIGH CLEARANCE VERSIONS REQUIRE WELDING AND ARE NOT ZINC PLATED*

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

• 7075 Aluminum Split-tapered bushings

• Huge 7/8″ Teflon lined Spherical Bearings 

• All assemblies are greased and lubricated

• Choose from press-in or weld-in styles below 

• 7/8″ 4140 Hardened custom spec bolts 

• 7/8″ Low profile locknut

**High Clearance versions require welding!

Fitment: Please choose an option based off of the year vehicle your axle was originally installed in as well as your desired bushing offset (0 degree, 1.5 degree, or 3 degree). 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. 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 ball joints 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.

Looking to weld your kit?: The press fit systems can be welded in by simply removing the clear zinc coating, please see the instructions for more details.
