Product Details
This Whiteline Rear Differential Bushings - Mount In Cradle fits the 2009-2025 Subaru Forester X. Included: 2 shell bushings, 2 tubes, 4 washers, an install guide, and grease. The listing names the X trim. Position: rear. The chassis code on the listing is SH/SJ/SGP. Whiteline part number: KDT906.
The differential is hung from the chassis on bushings that are soft for comfort. Under hard acceleration and braking they let it rock, so power reaches the wheels a moment late and the rear end can feel loose. A firmer bushing holds the differential more steadily, which sharpens throttle response. Polyurethane resists deflection far better than the soft rubber it replaces.
Whiteline rates the install as difficult and lists about 4 hours. Get the car aligned once it is back on the ground. Other Whiteline parts we list for the Forester: Adjustable Rear Sway Bar Link, 14mm Adjustable Front Camber Bolts, and Adjustable Sway Bar Vehicle Link Kit.
Features
- Bushing material: The bushing material is polyurethane, a firmer choice than rubber.
- Self-lubricating: Grease reservoirs inside the bushing feed lubrication as it moves.
- Bushing compound: A synthetic elastomer compound resists oil, grease, ozone, and weathering.
- Corrosion protection: A protective plating covers the metal components to guard against corrosion.
- Install guide: Step-by-step installation instructions come with it.
- Bonded design: Bonding adds durability in high-load use.
