Perrin Diffrential Lockdown System - Subaru WRX STi 2015-2021

The PERRIN Differential Lockdown eliminates the excessive movement of the rear differential under hard acceleration and deceleration, resulting in a more solid and responsive feel. This upgrade helps transfer power to the wheels more efficiently, improving traction and overall drivability.


Key Features

  • Reduces Differential Movement:
    Factory rubber bushings allow the rear differential to move under load, creating wheel hop and drivetrain lash. The PERRIN Differential Lockdown brackets hold the differential securely in place.

  • Improves Acceleration & Traction:
    Minimizes drivetrain slack, giving a more direct connection between the throttle and wheels.

  • High-Quality Construction:

    • CNC‑machined 6061 aluminum brackets

    • Durable black anodized finish to resist corrosion

    • Stainless steel hardware included

  • Simple Bolt-On Installation:
    Installs using factory mounting points without permanent modification.


Benefits

  • Eliminates clunking and wheel hop under hard launches

  • Provides a more precise, sporty driving feel

  • Improves power delivery to the ground during acceleration

  • Increases overall stability of the drivetrain


Included Components

  • 2x CNC‑machined aluminum differential lockdown brackets

  • Complete stainless steel hardware kit

  • Installation instructions
