SPC Performance 23130 4x4 Sleeve Assortment (9)

The SPC Performance 23130 is a comprehensive 9-piece camber/caster (cam/cas) sleeve assortment designed for 4x4 trucks and SUVs. This complete set allows technicians to independently adjust camber, caster, or both simultaneously using a single upper ball joint sleeve swap — no cutting, welding, or suspension modifications required.

The set includes nine individual sleeves covering the full adjustment spectrum from 0° to 2.00°, in 0.25° increments. Begin by installing the included zero-degree reference sleeve (23139) to establish a baseline, then select the correct sleeve to achieve the desired alignment specification. To split camber and caster adjustment equally, simply rotate the sleeve 45°. Estimated installation time is approximately 0.5 hours per side, and one sleeve is required per wheel.
