Product Description

The Whiteline KDT903 tightens up the rear differential mount on Subaru WRX/STI and related platforms by inserting a firmer synthetic elastomer bushing into the voids of the factory rubber mount. Rather than a full replacement, it works alongside the OE bushing to reduce differential movement and keep pinion angles consistent under load.

The result is more predictable power transfer to the wheels and a noticeably tighter gear shift feel, since less energy is lost to bushing flex during acceleration and deceleration. It's a low-cost, high-value upgrade for anyone looking to firm up rear-end response without a full differential mount swap.
