Moog EC679 Drive Shaft Flex Joint Coupler

The Moog EC679 is a premium replacement drive shaft flex joint coupler engineered to restore smooth, quiet driveline operation. Serving as the critical connection point between the transmission and differential, this driveline coupler functions similarly to a universal joint, absorbing driveline vibrations and isolating noise, vibration, and harshness (NVH) before they can transfer into the cabin.

Key Features:

• Restores Ride Quality – Isolates driveline vibrations to reduce NVH and bring back smooth, like-new performance
• High-Grade Construction – Reinforced nylon 66 wire embedded within a premium rubber body for optimal strength and extended coupler life
• OE-Quality Replacement – Engineered as a direct replacement for worn or deteriorated factory couplers
• Installation Ready – Includes premium hardware for straightforward installation where applicable
• Rigorously Tested – Validated through comprehensive engineering and development testing by Moog's design team
• Broad Coverage – Designed to serve a range of foreign and domestic applications

Moog has been the trusted name in chassis and driveline components for over 100 years, consistently engineering parts that meet or exceed OE standards. The EC679 upholds that tradition, delivering dependable, long-lasting driveline performance.
