Product Review

The SGF couplers are designed by SGF for the OEM's to their specific vehicle specifications. This is the exact coupler you would purchase from BMW, Mercedes or Cadillac. With drive shafts rotating in excess of 3,000 RPM's, do not risk installing a low quality flex coupler in any of your vehicles. Non-SGF flex couplers do not adhere to the quality requirements demanded by the Original Equipment Manufacturers (OEM).
