Did you lower your car and now have the dreaded axle wobble when you take off from a stop? These 3/8" spacers install on the studs of the stock 3800 series II and III engine and transmission mounts and will help get closer to the stock axle angle. They might not fix every car, but they sure help. However moving the engine and trans upwards will bring them closer to the hood, so make sure you have enough hood clearance to install them.
They raise the engine and trans 3/8".
Will not work in LS4 or H-Body applications.
