Action Clutch ACR-3758 Ironman Unsprung Single Disc Clutch Kit

The Action Clutch ACR-3758 Ironman Unsprung Single Disc Clutch Kit is engineered specifically for dedicated high-powered race vehicles, delivering durability and reliable performance under extreme track conditions. Offering 250% increased holding capacity over the factory clutch kit, this is the ideal upgrade for drivers who want maximum torque handling without stepping up to a multi-disc system.

Built around Action Clutch's legendary American Sintered Iron friction material and a dual clamp load heavy-duty pressure plate, the Ironman Unsprung delivers an aggressive on/off clutch engagement with impressive holding capacity for a single-plate design. The unsprung (rigid) hub disc eliminates clutch chatter, though light engagement noise and some gear rattle are normal characteristics of this race-focused design.

• 250% increased holding capacity over the OEM factory clutch kit
• American Sintered Iron friction material for rapid heat dissipation and long durability
• Dual clamp load heavy-duty pressure plate for maximum torque transfer
• Full-face unsprung (rigid) sintered metallic clutch disc
• Ductile iron friction plate on all clutch covers

Important Notes:

• Track use only — this kit is not intended for street or daily driving
• Unsprung design results in harsher engagement; no drivetrain shock reduction
• Break-in required: 500 street miles keeping RPM under 4,500, no more than half-throttle, no boost (if applicable)
• Proper break-in is required to retain product warranty and ensure longevity
