SPL BMW F2X F3X Adjustable Front Caster Rod Monoball Bushings are the ultimate front control arm bushing upgrade for BMW 2 Series F2X and 3 Series and 4 Series F3X chassis. Replace the soft, factory rubber caster rod bushings with low friction, articulating spherical bearings and transform steering precision, braking stability and handling feedback on fast road and track day builds.
These SPL Parts FKS Series caster rod bushings use massive 1 inch FK Racing Bearings with self lubricating Teflon liners inside precision CNC machined 6061 T6 aluminium housings. The result is reduced bushing deflection, consistent alignment under load, sharper turn in and improved confidence under hard braking. Innovative offset bearing spacers provide adjustable caster correction with +/- 4 degrees of front caster adjustment so you can dial in the ideal alignment for street or track.
