DETAILS

Here, you are looking at the Whiteline Rear Diff Positive kit bushing kit. 

Thee bushings are designed to reduce the initial torque loss and movement through the rear differential mounts during acceleration and deceleration. These inserts fill in the voids that are in the OEM bushings and help to stiffen the rear differential. They are a great upgrade for anyone looking to improve the performance of their car.

Features: 

  • The latest in material formulation technology boasts resistance to oil, grease, ozone and weathering.
  • Supplied with extreme pressure molybdenum disulphide (LM) based grease for extended life.
  • Internal grease reservoirs provide continual self-lubrication for optimum friction management.
  • Inserts are designed to work with the original factory bushing rather than replacing it.
  • Protective plating on all metal components acts as a hard skin that is much tougher than conventional paint allowing this product to withstand the toughest conditions and resist corrosion for years to come.
  • This kit is covered by a limited lifetime warranty including parts and labour.
  • Install guide included providing detailed instructions on how to install your new purchase .

IMPROVE GRIP, HANDLING & PERFORMANCE.

Cornering loads are spread more evenly across the tires delivering more grip and, frankly, that’s what it’s all about. You also get improved tire wear as your tires stay flatter and more upright. Comfort improves because your car sits flatter through bends meaning less movement inside the vehicle.

These are sweet

Was kind of a pain to install, but a floor jack made it a breeze as well as a flathead. Most definitely made the car smooth and flat when powering.

Jim,

Thank you for taking the time to leave your 5 Star Review! The Whiteline Rear Differential Positive Power Kit definitely improves handling, and it is great to hear your install went smoothly with a floor jack! Enjoy the upgrade!

Awesome!!

Simple install, except the diff carrier!
Get a floor jack for the driveshaft! Once the two inner bolts on the carrier are through and the nuts are started, put the jack on the carrier to push it in!
Had to use a breaker bar to get all bolts loose and back on. And im not a weak dude lol
It definitely made a noticeable improvement in the car, minimal nvh

We appreciate your 5 Star Review, Tim!

Awesome install tips—definitely helpful for others tackling this upgrade. It’s great to hear the difference is noticeable with minimal NVH! Enjoy the improved performance!

2017 STI Whiteline Rear Differential Positive Power Kit Inserts

Definitely worth the money! Had access to a car lift so install was a breeze but still doable on jack stands in your driveway. Paper install instructions that came with it were moderate at best so do yourself a favor and just look it up on YouTube. Car feels "tighter" but also paired it with the other bushing insert kit so hard to tell which made a bigger difference. Still would recommend this inexpensive, easy upgrade!

K. Mathews,

Thank you for taking the time to leave your 5 Star Review! The rear diff power kit is a solid upgrade, and great call on checking YouTube for install guidance. Pairing it with the other bushing insert kit must make for a serious improvement! Enjoy the ride!
