Sonnax Smart-Tech Clutch Kit - SX77734-01K

Sonnax Smart-Tech clutch kit 77734-01K includes the eight .067" BorgWarner high energy frictions and seven .095" Lindered steels recommended for use with Sonnax Smart-Tech input housings. These patented 3-4 clutch upgrades make room for a taller clutch pack, allowing one additional OE thickness friction and steel plate. Combining the housing with this clutch kit is the best way to optimize clutch capacity and guard against burnup in GM 4L60, 4L60-E, 4L65-E and 4L70-E transmissions.
