This M5x8 anodized aluminum set screw is made as a direct replacement for the spring-tension (ride-height) adjustment screw used when fitting inner-spring lower arms on Yokomo R12 and GT series 1/10 scale chassis. It provides a lighter anodized-aluminum option while keeping thread profile and mounting position identical to the original part.
Installation is simple: thread the screw into the existing adjustment hole on the lower arm, check for smooth engagement and the correct spring preload, then verify full suspension travel and clearance. The screw is intended to set ride height and spring preload during suspension tuning and does not alter spring rate or damper settings.
Choose this part when converting to inner-spring lower arms or when a lighter replacement is needed for consistent ride-height adjustments during setup and maintenance.
