Subaru Impreza Diff Subframe Lockdown - Rear - Perrin Performance - `93-`07 is a rear differential lockdown designed to tighten up the drivetrain and improve throttle feel. This Perrin Performance piece helps reduce unwanted differential movement for a more controlled driving experience.

Engineered for enthusiasts who want a firmer rear subframe connection, the Perrin rear differential lockdown focuses on increasing drivetrain rigidity and delivering sharper, more responsive throttle control. It works with factory mounting points and complements other chassis upgrades to reduce flex under load, helping the rear end feel more planted during spirited driving.
