Sonnax high capacity 3-5-R apply ring 104548-01 for GM 6L80 units is shorter than the OE apply ring. When the Sonnax apply ring is installed and the OE waved plate is eliminated, this allows for one additional OE thickness friction and steel plate to be installed increasing the 3-5-R clutch capacity by 25%. The extra clutch and steel also help dissipate heat resulting in a significantly more durable 3-5-R clutch pack that can handle modified engines with increased power output.
