DETAILS

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 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:

  • (4) PERRIN Diff Lockdown Bushings
  • (2) PERRIN Large Subframe Bushings
  • (2) PERRIN Subframe Bushings
  • (2) M12 Hex Head Bolt
  • (2) Metal Bolt Sleeves

Great products

Like always, theyre great quality products. Tightens up the back end alot, does come with some nvh but is easily tolerable

Thank you for your 5 Star Review, Bill!

We are glad the Perrin Subframe Lockdown Kit tightened up your vehicle’s rear end. While some NVH is expected, we are happy it remains manageable for you.

Got these quick and was able to get them in the car within 2/3 hours. Installation difficult is honestly a 4/10 in my opinion and I would say anyone can do it in there garage as long as they have the adequate tools. A difference can be felt now when coming off the line as it feels as if the power is more planted down now as well when going between gears. As always thanks to the whole team at Subimods as they always come thru and get parts to me quick.

Randy,

Thank you for your detailed 5 Star Review! We are thrilled the Perrin Subframe Lockdown Kit improved your driving experience. Your insight into the installation process is valuable for others considering this upgrade.

Awesome little kit for a weekend project.

The install / instructions were pretty straight forward. I live in the rust belt and getting said old hardware out was not much fun but after a week of PB-Blastin i got everything out. I will say gathering up OEM Subaru hardware for reinstall is definitely worth your while.

Zach,

The Perrin Subframe Lockdown Kit is absolutely a worthwhile upgrade! Dealing with rusted hardware can be a challenge, but it is great to hear that the installation and instructions were straightforward overall. Gathering OEM Subaru hardware for reinstallation is a smart move for ensuring durability and reliability. Thank you for your 5 Star Review! Enjoy the improved handling and stability from your subframe lockdown kit!

Makes the car much more stiff with a little more NVH

Shaun,

Thank you for sharing your 5 Star Review and experience with the Perrin Subframe Lockdown Kit for your WRX/STI! We appreciate your feedback and are glad to hear that the kit has effectively increased the stiffness of your car. It is worth noting that a slight increase in NVH (Noise, Vibration, Harshness) is expected with such modifications. If you have any further questions or if there is anything else we can assist you with, please feel free to contact the Subimods Team.

Regards,
