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
