South Bend Clutch is a forth generation clutch rebuilder & designer. Three Brothers, Woody, Andy & Peter Pyfer carry on the Heritage of their Father and Grandfather. The business started out rebuilding clutches over 30 years ago and even added the Kevlar linings for higher performance and extended wear.


Then about 8 years ago they noticed that the stock clutches for the diesel trucks weren't holding up to the heavy towing or with the modifications being made to the trucks. They designed their own line of high performance clutches with many choices including double and triple disc pulling clutches.

The Pyfers' dedication to maintaining a small business attitude is remarkable. South Bend Clutch's business has more than quadrupled in size over the last several years with the first building expansion in 1995 and another in 2008. South Bend Clutch has also expanded into the field of Cryogenics. They have been using Cryogenic treatment to enhance their products as well as improve the performance and life of their machining tools. South Bend Clutch has had great success with Cryogenics and is now offering this amazing service to the public.

South Bend Clutch has an extensive list of distributors and resellers/installers which can be found on their website but they also sell directly to the public.
