Perrin Subframe Lockdown 2008-2014 WRX / 2008-2014 STI / 2008-2011 Impreza

Take full control of your Subaru’s rear end with the PERRIN Subframe & Diff Lockdown Kit. Designed to drastically reduce unwanted drivetrain movement and subframe flex, this kit gives your WRX or STI a more direct, confident feel—especially under hard acceleration, cornering, and shifting.

Crafted from premium urethane, these bushings effectively locks down the rear subframe to minimize play. This results in improved traction, more predictable handling, and a tighter, sportier driving experience without adding excessive noise or vibration.

Features:

• Reduces Rear-End Slop: Firmly secures the rear subframe for improved power transfer and chassis response.

• Improves Launch and Handling: Reduces wheel hop and helps maintain rear-end stability under load.

• Durable Construction: Urethane bushings built for performance and longevity.

• Easy Installation: Direct bolt-on design; no permanent modifications required.

Included:

• (4) Subframe Lockdown Lower Bushings
• (4) Subframe Lockdown Upper Bushings
