Pontiac G8 Suspension Upgrade Part 1- Pedders Track II Suspension
|
The aluminum three-point mount differential anchors the IRS. With the unit unbolted, the O.E. bushings are pressed out with a proprietary Pedders press plate and receiver and the new Pedders EP1167 differential bushings are slid in. This view is from the front of the vehicle looking toward the rear. (The male pilot that will insert into the female receiver on the driveshaft discussed in the previous caption is shown as well.) Pedders replaces the O.E. rubber bushing designed specifically to meet NVH standards with a urethane bushing designed for performance and comfort. Although traditionally we would compare hardness ratings through durometer readings, in this case the Pedders "bits" are superior to O.E. parts because of their design and the placement and size of NVH voids.
