Perrin Rear Subframe Lockdown Kit 02-07 WRX / 04-07 STI / 1998-2008 Forester / 1993-2007 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 Subaru a more direct, confident feel—especially under hard acceleration, cornering, and shifting. Crafted from high-quality CNC-machined aluminum and premium urethane bushings, the kit effectively locks down the rear subframe and rear differential 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 and differential for improved power transfer and chassis response. Improves Launch and Handling: Reduces wheel hop and helps maintain rear-end stability under load. Durable Construction: Anodized aluminum spacers and high-durometer bushings built for performance and longevity. Easy Installation: Direct bolt-on design; no permanent modifications required. Included: (2) M12 Hex Head Bolts (2) Metal Bolt Sleeves Warranty & Instructions
