Whiteline gearbox mount side support insert. This bushing reduces gearbox movement under acceleration to improve drivetrain stability; it’s recommended for competition use only as it can increase NVH. Engineered for a secure fit, the insert helps isolate vibration while maintaining load handling under hard use. The kit contains two bushings to service the mount and restore steadier gearbox behavior.
