What It Helps Address

• Driveline vibration from a worn center support bearing
• Noise from a deteriorated drive shaft support mount
• Excess movement in the center of the drive shaft assembly
• Fitment issues when replacing the original center support on Silverado and Sierra trucks

Installation Notes

Verify the bearing I.D. and vehicle application before installation. This part cross-references Anchor 6064 for the same application. For best results, compare the original mount and driveline configuration on your Chevrolet Silverado or GMC Sierra before replacement.

Quality Assurance

Pioneer Mounts use application testing on vehicle-specific fixtures through the Sure-Fit System. The housing is manufactured from durable metal or aluminum, and the bonded rubber is selected for the specific application to support vibration isolation.
