This SPC sleeve changes caster and/or camber by 0.25° and is widely used on many Ford and Mazda RWD and 4WD trucks. Installation requires removal of the upper ball joint pinch bolt and, when present, the top snap ring; use a sleeve puller (77880 or 88830). Rotate the sleeve 45° to split camber and caster change; install one sleeve per wheel and use a zero‑degree sleeve to check initial readings.
