Action Clutch ACR-1582 Ironman Unsprung Clutch Kit for Nissan Sentra QR25DE

The Action Clutch ACR-1582 Ironman Unsprung Clutch Kit is engineered specifically for high-powered race vehicles with Nissan Sentra 2.5L QR25DE engines. This dedicated track-use clutch features American sintered iron friction material paired with a dual clamp load heavy-duty pressure plate that ensures maximum torque holding capacity. Designed for track-use applications, this kit delivers a 250 percent increased holding capacity over factory specifications.

Key Features:

• Rigid unsprung hub-type disc with American-grade rivets and durable American sintered iron friction material
• Ductile iron friction plate with reinforced heavy-duty drive straps
• 4-stage heat-treated diaphragm spring, 100 percent dynamically spin balanced
• Aggressive clutch engagement with on/off feel without introducing clutch chatter, though some light engagement noise and gear rattle may occur
• Nearly double the clamping force with some slippage on takeoff for superior repeatability and endurance
• Multiple quality checks after assembly to ensure consistent performance

Important Application Notes:

• Not intended for street use and should only be used in race applications
• Using an unsprung clutch disc on stock or lightly modified engines in daily/street driven vehicles can break the rivets on the clutch disc hub
• Requires 500 street miles break-in: keep RPMs under 4500, no more than half-throttle, no boost if applicable

This complete clutch kit is ideal for racers seeking an affordable high-torque holding capacity solution without upgrading to a multi-disc setup. All Action Clutch products are hand-assembled in the USA and meet SFI Spec 1.1 certification standards for replacement flywheels and clutch assemblies.
