Spec Clutch SF361 Stage Performance Clutch Kit - 1

The Spec Clutch SF361 Stage 1 Clutch Kit is an entry-level performance clutch engineered for bolt-on naturally aspirated engines and mildly modified forced induction applications. It delivers stock-like daily drivability with significantly improved holding capacity and wear characteristics over the OEM clutch.

At the heart of the Stage 1 kit is an integrally molded carbon Kevlar-based, high-performance organic friction disc that provides smooth clutch engagement and excellent service life. The lining features a steel backing bonded directly to the disc for added strength under high clamp loads and elevated temperatures. The high-clamp pressure plate increases clamping force over stock, delivering more reliable power transfer without the harsh on/off engagement associated with race-only clutches.

Key Features:

• High-clamp performance pressure plate for increased torque holding capacity
• Carbon Kevlar-based multi-compound woven organic friction disc for smooth engagement and long life
• Steel-backed clutch disc for strength under high clamp loads and heat
• High-torque double-sprung hub with spring cover reliefs for driveline vibration absorption and flexibility
• Heat-treated hub components for strength and long-term durability
• Clutch alignment tool included for simplified installation

Recommended Driving Applications: Street, Drag, Drift, Road Race, Rallye, Pulling, Autocross

Installation Note: Unless installing a new SPEC flywheel, the existing flywheel must be resurfaced prior to installation to ensure proper friction surface integrity. A minimum 450-mile break-in period of primarily city and stop-and-go driving is required before full-throttle engagement, drag launching, or speed shifting.
