The weak OE backing plate flexes during clutch apply, allowing heat to build up unevenly within the clutch pack’s limited space. Stop the flex and you stop 3-4 clutch failure.\u003c\/p\u003e\u003cp\u003eSonnax Smart-Tech input housing kit 77733-12KA makes room for a taller clutch pack anchored in place by a stronger backing plate — the most reliable way to increase clutch capacity and protect against destructive heat.\u003c\/p\u003e\u003cp\u003eTo avoid the problems found with older, OE housing designs, Sonnax starts with the latest production, new housings from GM. These improved housings have splines for the input shaft that are cut at minimum spec for reliable shaft retention and sealing. The housings also benefit from added material for a thicker, more consistent cross-section that protects against breakage.\u003c\/p\u003e\u003cp\u003eSmart-Tech input housing kit with heavy duty input shaft 77733-12KA fits 300mm reluctor-style units. The high-strength shaft features many unique refinements available only from Sonnax, including a unique design that protects against failure from stress cracks. Both the housing and shaft also are available separately.\u003c\/p\u003e\u003cp\u003ePhysically larger clutch pack area for increased 3-4 clutch capacity without sacrificing clutch durability.
