Corvette differential mounts are made from chunks of rubber with 4 studs sticking out of them. Cheap and easy to make en-masse they do their job of minimizing NVH for street driving perfectly well. Unlike the stock oil filled motor mounts, they are not prone to failure and can last seemingly forever in a street car application. If you’re driving your Corvette to the grocery store and church, chances are you don’t need our mounts, and you can stop reading now and save some money.
However when it comes to performance driving you want to mitigate the pendulum effect of the drivetrain while flying thru turns at 1.5+Gs or accelerating like a bat out of hell on the dragstrip. In these cases you want the mounts to be as stiff as possible without inducing any more NVH to the driver than necessary. For that we proudly introduce our Double Barrel Diff Mount for the C5 Corvette.
Our design uses two pivot points with rubber and steel centers so that the transmission can’t twist from side to side or move front to back. The rubber center sections will dampen just enough vibration so that this mount isn’t “solid” and therefore noisy while trying to knock your teeth out. Most other designs on the market use a single pivot point with a much longer upper bar which requires rubber pads on the ends to keep the transmission from twisting. These rubber pads are prone to failure as the rubber vibrates and wears out, and the large upper bar make for a heavier design and increases the difficulty of installation. Our mount weighs 2.2 lbs while the factory rubber mount weighs 3.4 lbs and is truly one of the easiest parts to install on a C5.
All parts are made from 6061-T6 aluminum and are machined in our 5 Axis CNC. The parts feature our sunk in hex-design bolts to make installation as easy and as painless as possible. All hardware is Grade 10 and yellow chromate plated and nylon locking nuts are included, or you can reuse the factory hardware if you prefer. Parts are red and black anodized to resist oxidation and look sexy.

All of the machined parts are made at our facility in New York, USA and these mounts are guaranteed for life. If any part ever fails on them we will replace them free of charge, no questions asked.
