The YOKBMS1270 front shock coil spring is intended for RC front suspension applications as a replacement or tuning option. It enables changes to spring stiffness without needing to alter damper housings or shafts.
Role during setup: use spring swaps or preload adjustments to control front roll, responsiveness and weight transfer. Coordinate spring choice with damper oil and ride height for stable on-track behavior.
Installation guidance: fit the spring onto the shock shaft and seat it at the perch, verify equal seating on both sides, and ensure no binding against the shock body. Use matched left/right springs and recheck preload after a shakedown run.
