These adjustable arms replace the OEM rubber-bushed trailing and caster links to deliver a wide range of front caster and rear caster adjustment for precise alignment, sharper turn-in, and correction of side-to-side caster variance. PTFE-lined FK spherical bearings replace the soft factory rubber bushings for a firmer, more responsive steering feel. The 6061-T6 billet aluminum arms and links pair with a 4140 chromoly clevis stud to cut unsprung weight while holding high strength and stiffness. Stainless steel adjustment spacers set anti-dive when run up front or anti-squat when run at the rear, and an exclusive 360 degree rotating clamp locks in alignment settings without fighting jam nuts. Blue anodized titanium hardware trims further weight, and the arms are engineered and assembled in the USA for high performance street and race use.
