If you want crisper handling on tacky surfaces the Yokomo RS-501SP 40T pulley is a solid choice. Designed for RS1.0 and RS2.0 cars, it refines how the front axle reacts for steadier mid-corner balance.
The RS-501SP 40T cuts down unnecessary front diff movement so corner exits are smoother and wheelspin is reduced. That stability gives drivers more confidence when powering out of turns.
Compatible with RSR-010, RSR-020 and RSR-010-1 chassis. To keep driveline losses low use double joint universals and check that the pulley runs true under load for consistent rotation.
