Product Description

Skyjacker's RA135 extended radius arm kit is built to correct suspension geometry on 4-6 inch lifted, TTB-equipped 4WD Ford compact trucks and their Mazda counterparts. By relocating the radius arm pivots and extending arm length, the system helps recover caster, improves on-road tracking, and enhances suspension function on lifted applications.

The kit includes model-specific radius-arm brackets, a reinforced transfer case crossmember, and a polyurethane strut arm bushing kit, delivering a comprehensive, bolt-on solution (with drilling) that integrates with OEM TTB axle beams and coil springs. Ideal for 1983-1997 Ranger, 1984-1990 Bronco II, 1991-1994 Explorer, 1991-1994 Navajo, and 1994-1997 B4000 4WD platforms.
