does jr make their own stepper pulley

[Grado]

if so how does it compare with the mvm pulley?

[00TypeR]

they don't make one. they do make a diff crank pulley that ups the boost.

if you ever need a stepper pulley, just go mvm. you wont regret it.

MVM all the way, i use a CRV crank pulley and jim told me it put down 10-10.25 on the dyno. but i have to deal with belt slippage and more wear on the alternator.
