Subaru Crosstrek Differential Lockdown System - Rear - Perrin Performance - '24-'25: The PERRIN Rear Differential Lockdown is engineered to increase drivetrain rigidity and deliver sharper, more responsive throttle control for 2024–2025 Crosstrek models. It’s a vehicle-specific solution for owners who want a firmer, more predictable rear-end feel.

This rear differential lockdown reduces differential housing movement under load, helping the drivetrain respond more consistently during acceleration and quick transitions. Designed by PERRIN Performance for direct fitment on '24–'25 Crosstrek models, the part follows PERRIN’s Subaru application coverage (including 15–21 WRX & STI and 12–25 Impreza). The result is improved confidence when pushing the car on back roads or when driving in conditions that challenge traction and chassis control.
