PERRIN Performance Transmission Mount Kit

The PERRIN Performance Transmission Mount Kit is designed to reduce drivetrain movement during hard acceleration, deceleration, and cornering, giving you a more connected and precise driving experience.

By replacing the soft factory mounts with stiffer, large-diameter 70a Durometer polyurethane bushings pressed into CNC-machined aluminum mounts, this kit minimizes drivetrain slop and maximizes power transfer to the ground. Whether you’re launching at the drag strip or pushing through tight autocross corners, the PERRIN Transmission Mount Kit helps deliver more accurate and consistent performance.

Built with a thick steel base plate and heavy-duty hardware, the PERRIN mounts absorb extreme vibrations and noises while preventing excessive transmission movement under extreme loads. Unlike OEM mounts held together by bonded rubber and small tabs—which can fail—the PERRIN design features a strong interlock to keep your transmission securely connected to the chassis.

Key Features:

• Reduces drivetrain movement for improved power transfer

• Large 70a Durometer polyurethane bushings for durability and vibration absorption

• CNC-machined aluminum mounts with heavy-duty steel base plate

• Designed for aggressive driving and performance applications

• Prevents mount failure with a robust interlock design
