Featuring a 100mm bolt circle and 12mm bolt holes, it incorporates a unique internal fiber wrapping for enhanced strength and torsional stiffness, capable of handling rotational speeds above 3,000 RPM. Manufactured by SGF, a trusted name since 1946, this flex coupler guarantees authentic fit and durability, ensuring your vehicle performs at its best without compromise.

## Description

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). *** FLEX DISC ONLY! *** NOT A KIT ***

## Features

- SGF flex couplers have the part number formed into the flex coupler itself. By comparing the number on your flex coupler with the SGF part number, you insure the correct fit every time.
- SGF has manufactured over 90% of OEM flex couplers since 1946
- Many aftermarket couplers do not contain the internal fiber wrapping that characterize genuine SGF couplers. This internal wrapping determines strength, stiffness and the torsional requirements your vehicle requires
- 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.
