3680-30 Specifications
Application: GM | Bore ID: 1.181" (30 mm) | Center to Base: 1.500" | Type: Rubber-isolated center support bearing
The 3680-30 sits at the 1.500" position in the GM 30 mm bore range, between the compact 1.375" units and the mid-height 1.750" versions. This height is used on GM platforms where the driveshaft routing and crossmember geometry require exactly this drop.
One GM-specific engineering note: the bonded rubber isolator on the 3680-30 uses a compression-dominant load path -- the rubber is designed to be loaded in compression (squeezed between inner and outer brackets as the shaft pushes down) rather than in shear. This design choice provides maximum isolator fatigue life. If the vehicle has been fitted with aftermarket low-profile tires that reduce wheel well clearance, the resulting changes to driveshaft phasing may introduce a shear component to the center bearing load, accelerating rubber deterioration. Inspect for tire modifications when diagnosing repeat center bearing failures on GM vehicles.
