PERRIN Pitch Stop Mount

Reduce drivetrain shudder and slop under hard acceleration with the PERRIN Pitch Stop Mount. The factory pitch stop mount is designed to control engine and transmission pitching under light to moderate acceleration, but it’s made of plastic and soft rubber bushings that allow excessive movement when power and drivetrain upgrades increase torque.

Under aggressive driving, the drivetrain twists front-to-back due to axle torque, causing slop and unwanted shudder. The PERRIN Pitch Stop Mount is engineered to significantly reduce this movement by controlling drivetrain pitch during both on and off throttle conditions. This delivers a more connected driving feel and helps transfer more power to the wheels by eliminating lost energy.

Machined from durable 6061 billet aluminum, the mount uses a combination of 90a and 70a durometer bushings that are stiff enough to control movement without adding excessive noise, vibration, or harshness (NVH).

Key Features:

• Reduces drivetrain pitch and shudder under hard acceleration

• CNC-machined 6061 billet aluminum body

• Dual durometer polyurethane bushings (90a and 70a) for optimal stiffness and NVH balance

• Improves power transfer and driving feel

• Designed for aggressive driving and performance upgrades
