Product Description

The SuperPro SPF3199K is a polyurethane gearbox crossmember isolator mount bushing kit designed to replace the worn OEM rubber bushings at the front position of the transmission crossmember on a range of Subaru AWD platforms. Over time, the factory rubber isolators soften and crack, allowing the gearbox to shift under load - leading to vague throttle response, imprecise shifting, and drivetrain vibration. SuperPro's polyurethane compound eliminates this movement while still retaining an acceptable level of NVH isolation, making it well-suited for both performance street builds and track use.

Installation is a direct OEM replacement - the bushings slot into the existing crossmember housing using the factory crush tubes, which must be retained from the original setup. The kit includes an instruction sheet and covers both naturally aspirated and turbocharged variants across Subaru's Legacy, Outback, Impreza, WRX, WRX STI, and Forester XT lineups on the GH/GR/BP/BL platforms. Backed by SuperPro's Lifetime Warranty with no exclusions for off-road or competition use.
