SuperPro Rear Crossmember Mount Insert Bushing Set Subaru Legacy 1994-1999 | SPF1978K

Product Fitment:

1994-1999 Subaru Legacy

Upgrade your rear suspension with the SuperPro SPF1978K Crossmember Supplement Washers Bush Kit, designed to firm up the subframe-to-body connection and reduce axle tramp or unwanted rear-end movement. Over time, factory crossmember bushings can compress or void out, allowing excessive subframe flex that undermines handling, traction, and chassis stability. SPF1978K fills those voids and replaces the soft rubber with durable polyurethane bushings, delivering a tighter, more stable mounting.

The polyurethane material resists oil, water, road contaminants, and temperature extremes—dramatically outlasting standard rubber mounts. Once installed, the kit improves handling precision, rear‑end stability under acceleration or braking, and helps maintain chassis alignment under load. It’s especially beneficial for performance driving, spirited cornering, or any situation where you want improved control and feedback from your rear suspension.

Kit Includes:

• Multiple polyurethane bushings (as required for the crossmember mounting points)

• Steel sleeves / internal tubes (if applicable)

• All necessary washers or mounting hardware

Fitment: Rear axle / subframe-to-body mounting points on compatible models (check fitment list per vehicle)
Installation Time: ~4 hours
Warranty: Lifetime

Used properly, the SPF1978K kit delivers a firmer, more precise chassis feel and reduces unwanted rear movement—enhancing both handling and driver confidence.
