Fitment Notes

• Position: Rear differential mount, front/forward support location.
• Designed for the front bushings of the rear differential mounting system.
• Application-specific fitment varies by Subaru chassis and differential mounting configuration.
• One kit is required per vehicle.
• Designed for Subaru AWD drivetrains covered by Whiteline's application catalog.
• Does not represent fitment for every engine or trim available within a listed model; the specified chassis/differential configuration must match.
• 2026 fitment is not confirmed in Whiteline's current KDT905 application data.
• Professional installation is recommended because differential-support bushings require access to the rear drivetrain assembly.

Features

• Rear differential mount front/forward bushing kit.
• Positive differential retention helps limit unwanted differential movement.
• Helps maintain more consistent pinion angles under acceleration and load.
• Reduces differential movement during acceleration and gear changes.
• Helps reduce initial drivetrain torque loss.
• Improves power transfer from the differential to the wheels.
• Synthetic elastomer construction provides increased durability compared with conventional rubber.
• Resists oil, grease, ozone and weathering.
• Internal grease reservoirs provide continual self-lubrication for friction management.
• Application-specific bushing geometry is designed for Subaru rear differential mounting systems.
• Supplied sleeves/tubes support correct differential-mount installation.
• Designed to balance improved drivetrain control with acceptable NVH characteristics.
• Suitable for street, performance and motorsport-oriented Subaru applications.
• Serviceable replacement for compatible factory differential-mount bushings.

Product Description

The Whiteline KDT905 is a rear differential mount front/forward bushing kit designed for a broad range of Subaru AWD platforms. It replaces the applicable factory differential-support bushings with firmer synthetic elastomer components that help control differential movement, maintain more consistent pinion angles and improve drivetrain stability during acceleration and gear changes.

The KDT905 uses four Type 1 bushings measuring 55.4 mm in outside diameter, 25.4 mm in inside diameter and 27.1 mm in body length. The bushings incorporate Whiteline's synthetic elastomer formulation, which is designed to resist oil, grease, ozone and weathering, while internal grease reservoirs provide continual lubrication. Two supplied metal tubes/sleeves complete the mounting arrangement.

Documented applications span Subaru Forester, Impreza, WRX, WRX STI, Legacy, Liberty, Outback, Levorg and XV platforms from 1998 through 2025 depending on the model and chassis. Engine availability varies by platform and market, while all listed applications use AWD. One complete kit is required per vehicle, and installation should be performed by a qualified technician familiar with Subaru rear differential service.
