In a way to help reduce drivetrain shudder under hard acceleration one of the best things to do is installing an aftermarket pitch stop mount. The factory pitch stop mount is designed to control the pitching of a stock engine and transmission under light to normal acceleration, but with a heavy foot and a mod list longer than a mile you need this. PERRIN has provided you with a solution to this problem and it feels great. With the pitch stop made out of a thick slab of aluminum and a combination of stuff urethane bushings, you will not feel the movement you used to know.
