A clutch and damper assembly for a torque converter includes a clutch piston with a piston friction surface for engaging the clutch and an outer sealing diameter, and a damper. The piston friction surface is disposed radially inward of the damper and the outer sealing diameter is disposed radially outward of the damper. In an example embodiment, the clutch piston includes an inner sealing diameter disposed radially inward of the piston friction surface. In some example embodiments, the damper includes a resilient element and a drive plate. The drive plate is drivingly engaged with the resilient element and frictionally engageable with the clutch piston.
