Fitment Notes

• Position: Rear differential mount in cradle.
• Designed for the rear differential cradle mounting points.
• Compatible with the listed Subaru AWD platforms using the specified 60 mm differential-mount configuration.
• Legacy, Liberty and Outback applications use platform-specific chassis codes and may vary by market.
• WRX and WRX STI applications are limited to the documented chassis and model-year ranges.
• Forester SK fitment is documented through 2025; no 2026 Forester application was confirmed for this part.
• One kit is required per vehicle.
• Rear wheel alignment is recommended after installation according to Whiteline's installation information.
• Professional suspension/drivetrain installation is recommended due to the differential cradle mounting location.

Features

• Rear differential cradle mounting bushing kit.
• Positive differential retention design reduces unwanted differential movement.
• Helps maintain more consistent pinion angles under acceleration and load.
• Reduces differential movement during hard acceleration and gear changes.
• Helps reduce initial drivetrain torque loss.
• Improves power transfer from the differential to the wheels.
• High-load synthetic elastomer construction provides controlled differential movement.
• Polyurethane construction resists oil, grease, ozone and weathering.
• Internal grease reservoirs provide continual self-lubrication for friction management.
• Specially bonded construction is designed for high-load applications.
• 60 mm outside diameter is engineered for the applicable Subaru differential cradle.
• Supplied with sleeves/tubes and washers for the applicable mounting locations.
• Designed to improve drivetrain stability without replacing the complete differential cradle.

Product Description

The Whiteline KDT906 is a rear differential mount-in-cradle bushing kit designed for a broad range of Subaru AWD platforms. The kit replaces the applicable factory differential cradle bushings with firmer polyurethane/synthetic elastomer components that provide positive differential retention. By limiting unwanted differential movement, the KDT906 helps maintain more consistent pinion angles and improves drivetrain stability under acceleration and gear changes.

The bushings feature a 60 mm outside diameter and 38.2 mm body length and use internal grease reservoirs for continual self-lubrication. The 85A synthetic elastomer construction is designed to resist oil, grease, ozone and weathering while providing the higher load resistance required at the differential mounting points. The supplied tubes and washers complete the mounting hardware configuration for the applicable Subaru cradle.

Documented applications include Subaru Forester, Impreza, WRX, WRX STI, Legacy, Outback, Levorg and XV platforms spanning multiple generations and chassis codes. Engine configurations vary by platform and market, including naturally aspirated and turbocharged H4 engines as well as H6 applications. The kit is supplied for one vehicle and should be installed by a qualified technician familiar with Subaru rear differential and cradle service.
