After a few hard launches, OE Corvette transmission mounts are prone to fail; often reducing traction and creating powertrain shake (sometimes mistaken as wheel hop). aFe PFADT Series transmission mounts upgrade soft factory transmission mounts to a complete differential brace improving vehicle launches and overall feel. These transmission brace sets are designed to replace OE mounts and bolt to the differential to keep your powertrain in place, reducing the loads on your half-shafts and other driveline components. PFADT Series mounts are CNC-machined, 6061 anodized T-6 aluminum mated to nickel plated chassis mounts with replaceable polyurethane bushings. They are a direct-fit and Grade 10.9 hardware. Replace your OE mounts with aFe PFADT Series transmission mounts and see how much performance you've been missing!
