The PERRIN Rear Differential Lockdown for 2012–2026 WRX, STI, Forester XT, Impreza, and Crosstrek is a drivetrain support component designed to limit rear differential movement and improve throttle response and drivetrain precision.

  • Minimizes excessive rear differential motion under acceleration by locking down the differential mounting area to reduce drivetrain “slop.”
  • Precision machined aluminum lockdown plates included for solid support and long-lasting performance.
  • Engineered for direct bolt-on installation using basic hand tools; typical install time around 45 minutes.
  • Enhances driver feel by tightening drivetrain feedback with minimal increase in noise, vibration, and harshness (NVH).
  • Includes a set of two aluminum plates, warranty documentation, and installation instructions.

The design helps give a firmer, more connected sensation during hard throttle events on both street and track, making the rear end feel more responsive without requiring specialized tools to fit.

Are OEM products more expensive than aftermarket alternatives?

OEM products might have a higher upfront cost compared to aftermarket parts, but their superior quality and durability often make them a more cost-effective choice over time. Investing in OEM ensures you’re getting parts specifically designed for your vehicle, which can lead to better performance and longevity.

Can I purchase OEM parts online or do I need to visit a dealership?

You don’t need to visit a dealership to get OEM parts. You can conveniently purchase genuine OEM components from authorized distributors and reputable online retailers like Turbo Tech Performance. Our online store provides a wide selection of high-quality parts delivered straight to your door.

Are parts from brands like Mopar, ACDelco, and Motorcraft interchangeable between different vehicle brands?

No, parts from Mopar, ACDelco, and Motorcraft are typically designed for specific vehicle brands. It’s crucial to ensure compatibility with your vehicle’s make and model by checking part numbers and consulting with a knowledgeable expert.

Can I install OEM parts myself, or is it better to have a professional handle it?

While some OEM parts can be installed by DIY enthusiasts, the complexity of installation can vary. For the best results and to ensure proper fitment and performance, we recommend having a trained mechanic install the parts, especially if you’re unfamiliar with automotive repairs.

Do OEM parts come with a warranty?

Yes, many OEM auto parts come with a manufacturer’s warranty that covers defects or issues. Be sure to check the warranty details for each part at the time of purchase, and keep your receipt for any potential warranty claims.
