HRPartsNStuff Rear Swaybar
Product ID: 0450


 Our new swaybar / Anti-roll system transfers the force from one side to the other, doing a much more efficient job of equalizing the weight to each rear tire.  This in effect almost doubles the traction of a fast car with no air bags, because the passenger tire would have had very little weight on it.  With the added traction and the car being much closer to level, the car can now launch harder and straighter.  This reduces the chance of wandering out of the "groove" and further losing traction, while making it much safer to drive.  Not having to worry about the rear slicks getting cut or damaged from excessive body roll is an added bonus.

Poly Motor Mounts
Product ID: MM0101


HRPartsNStuff have designed and produced a new motor mount for GM G-Body vehicles from '78-'87, replacing GM part numbers: 25504647 left and 1258718 right. These are more commonly referred to as "Poly Motor Mounts", because they have Polyurethane bushings incorporated into their design. These new mounts have proven to be indestructible on engines making 1400+ HP, and are stronger than even the solid type mounts. The Poly mounts are designed to benefit the every-day driver as well as the full time racer, at any performance level.
