These sprags and roller clutch kits from TCI are all-new OEM assemblies. Replacing the forward sprag assembly and low-reverse roller clutch is a must when building a high performance 700R4/4L60E. These forward sprags are 29-element, which makes them ideal upgrades for earlier 700R4 transmissions that were built with weaker sprags from the factory.
