This belt wrap kit (BWK) is designed to Reduce Slip and maximize boost pressure by creating more contact surface with the supercharger pulley. Under heavy acceleration the M113K engines supercharger is known to slip on the belt which creates less boost. This kit allows the engine to maintain proper boost pressure.This Belt wrap kit will help to smooth out your power curve and can net a 1-2 psi increase at high RPM***Belt is not included unless you add it to your order!Please send us an email with your Pulley Size so we can match it up with the correct belt!
