Sonnax 76656-01K Smart-Tech Direct Clutch Drum & Shaft Kit

The Sonnax 76656-01K Smart-Tech direct clutch drum and shaft kit is a one-piece replacement for the two-piece direct drum and intermediate stub shaft assembly in an automatic transmission. It is built for heavy-duty and performance use, where the joint between the drum and the stub shaft is a common failure point. The kit fits all 2.84/1.55 gear sets.

Key Features:

• One-piece design removes the weak point where drum splines strip and shafts break
• Shaft is 50% thicker and twice as strong as OE
• Custom drum and piston give 17% more clutch capacity, with protection against burn-up
• Drum and shaft are precision-machined from hardened 8620 steel
• Forward sun gear is precision-machined from heat-treated 9310 steel

Kit Includes:

• Clutch drum with integrated stub shaft
• 31-tooth forward sun gear
• Piston
• Large outer seal
• Small inner seal
