THE PROBLEM
The stock center support bearing carriers hold the driveshaft in place with rubber so thin about 20 lbs of force moves them from center to the end of their travel. While that???s great for making sure no NVH makes it to the cabin, it doesn???t keep the bearing centered well under load, allows the bearing to sag over time and ruin driveshaft alignment, and creates slop in the driveline during shifts and throttle application. Over time the OEM bushing sags and becomes brittle, eventually dry rotting and cracking. Even on the best-kept cars, the stock bushing can start to from cracks in as little as 5-10 years. When the bushing lets go, it can lead to excessive vibration and clunking, and put more stress on the bearing. To make matters worse, the stock carrier is molded onto the center support bearing, so it???s not easy to replace without special tools.
THE SOLUTION
This upgraded units keep the driveshaft firmly in place at all times, and its solid construction ensures it will never wear out. The thick bushings ensure the driveshaft cannot move from center, maintaining driveshaft alignment at all times.
THE BUSHINGS
Two options are available for the bushings, both of which are many times over better than the stock bushing. We???ve paid close attention to the NVH levels associated with this upgrade. After extensive design iterations, we???ve come up with custom isolator bushings that separate the carrier from the body of the vehicle and mounting hardware. These carriers substantially reduce NVH levels.
The street bushings absorb most of the NVH from the drivetrain. Some light NVH is possible at some speeds in the form of a soft hum. With a modified exhaust or windows down you???ll probably never hear it.
The track bushings are for those who want no-compromise drivetrain performance. These may create a substantial amount of cabin noise. Not sure which is for you? They???re interchangeable so you can try them both.
INSTALLATION
Installation doesn???t require removal of the driveshaft. The 2-part design clamps around the OEM bearing. The old carrier must be removed, so a cutting tool is required.
FITMENT
Mitsubishi Evo 7/8/9 with OEM Driveshaft
We are currently looking into the DSS 2-piece driveshafts to see if one of the carriers will fit.
