Lower inner control arm bushings are one of the first components to wear on S13, S14, and S15 Silvia/180SX models, allowing excessive front-end flex that dulls steering and hurts alignment stability. SuperPro’s Control Arm Lower-Inner Bushing Kit (part SPF1483K) replaces the tired factory rubber with high-performance polyurethane bushings that virtually eliminate deflection for sharper turn-in, better caster control, and more responsive handling.
Featuring a stepped shell design (38mm to 40mm outside diameter) for perfect fitment, this kit restores front suspension precision and significantly extends service life compared to stock components. It’s an ideal upgrade whether you’re daily driving, tracking, or building a drift car.
