What is the main benefit of installing these differential mount bushings?

These bushings help maintain the correct pinion angles in your differential, especially during acceleration. This reduces initial torque loss, leading to more efficient power transfer to the wheels and a more responsive feel.

What materials are used in the Whiteline KDT906 kit?

The bushings are made from a synthetic elastomer that is resistant to oil, grease, ozone, and weathering. The metal components are protected with plating and powder coating, and the kit includes special grease for lubrication.

Does this kit come with everything needed for installation?

The kit includes the differential mount bushings and specialized grease for lubrication. An installation guide is also provided to help with the process, but you may need additional tools depending on your vehicle's specific setup.

Product Details

If you're looking to get more of your engine's power to the wheels, Whiteline's Rear Differential Mount Bushing Kit (KDT906) is a solid option. This kit is designed to keep your differential's pinion angles correct, especially under load. By doing this, it helps reduce the initial loss of torque when you accelerate, meaning more of the power your engine makes actually gets to the ground, giving you a more responsive feel.

Whiteline builds these bushings with a specially bonded design for strength, which is important in high-load situations like spirited driving or hauling. The synthetic elastomer material used is resistant to common automotive fluids like oil and grease, as well as ozone and weathering, so they hold up well over time. They even have internal grease reservoirs that help keep things self-lubricated for better friction management and extended life, and they come with a special molybdenum disulfide grease to get you started. The metal components are protected with plating and powder coating to resist corrosion and tough conditions.

This kit fits a wide range of Subaru models, including the Impreza, WRX, STI, Forester, Legacy, Outback, and XV Crosstrek from various years. An installation guide is included to help you through the process.
