Installation Tip
For maximum acceleration gains, pair with Dr. Pulley Sliding Roller Weights. When installing, hold the ramp plate firmly from behind so the internal sliders don’t slip out of position. Do not use an impact gun to torque the variator nut without ensuring the drive belt is fully slack — a pinched belt during torquing can cause the nut to back off under load.
