A SOLID REPLACEMENT FOR THE FAILURE-PRONE OEM UNIT
This is the PERRIN Pitch Stop Mount. This particular mount is made using durable aluminum materials which will support the torque and thrust that comes with modifications that will certainly overtake the strength of the factory pitch mount. The OEM unit is failure prone, and with time and mileage, it gets weaker and can simply snap. It will only get worse or break sooner when you add more modifications that increase the power and torque which will certainly surpass the limits of the OEM mount.
Reduce drivetrain shudder under hard acceleration by installing a PERRIN Pitch Stop mount. The factory pitch stop mount is designed to control the pitching of the engine and transmission under light to normal acceleration. Subaru's with power and drivetrain upgrades will need PERRIN's more aggressive option.
What Does a Pitch Stop Mount Do?
Under hard acceleration, the drivetrain is being twisted front to back from front axle torque twist. To control this front to back twisting, Subaru created a pitch stop mount. The factory pitch stop is made of plastic with soft rubber bushings, allowing for a significant amount of movement under hard driving conditions, creating drivetrain slop & shudder.
Why Do I Need The PERRIN Pitch Stop Mount?
The PERRIN Pitch Stop mount controls the movement of the drivetrain in both on and off throttle driving giving the driver a more positive feel and literally putting more power to the wheels by eliminating lost energy.
Construction
The PERRIN Pitch Stop Mounts body is machined from 6061 billet aluminum and features a combination of 90a and 70a durometer. The bushings are as stiff as possible without introducing excessive NVH. (noise vibration harshness)
5 Year Warranty
PERRIN Performance warrants to the original purchaser, all PERRIN products to be free from defects in material and workmanship within a sixty (60) months period from the date of manufacture. *Some exclusions apply.

Fast shipping and relatively easy installation makes this part a good buy for beginners as well as advanced tuners. It has solved a problem that I wanted it to solve, which was reducing some of the jerking between first and second gear and the “bounce” that occurs when engine breaking in a low gear. The trade off is a lot of NVH (cabin noise). I hear lot more sounds, some people on forums and YouTube say it’s not noticeable. I don’t know how that could be the case.
Easy to install. Compared to stock, it’s way thicker!
