When you lift your truck you affect caster and camber. SPC’s arm have +1 of caster built into them. Using its patented ball joint design, the arm will get you 0 to +4 of caster and 2 of camber. Get your tire where you want it in the wheel well: Use adjustment in the control arm and on the OE lower cams to maximize alignment angles and move oversized tires forward in the wheel well to minimize or avoid fender trimming. Do you need replacement cams for the lower control arm? Check out SPC p/n 25430, which will replace corroded cam bolt assemblies. On the adjustable ball joint SPC uses hex chromate free finish and offers a 700hr salt spray test for the best corrosion protection available.
