Spec Clutch SD741 Stage 1 Clutch Kit - Street & Performance

The SPEC SD741 Stage 1 Clutch Kit is engineered for bolt-on naturally aspirated engines and mildly modified forced induction applications. Designed to deliver stock-like daily drivability with significantly improved durability and torque capacity over the OEM clutch, the Stage 1 is SPEC's entry-level performance upgrade — ideal for street driving with occasional track use across disciplines including drag, drift, road race, rallye, pulling, and autocross.

Key Features:

• High-clamp pressure plate for increased clamping force over stock
• Multi-compound woven organic disc lining with integrally bonded steel backing for strength under high clamp loads and elevated temperatures
• Carbon Kevlar-based organic lining for smooth, progressive engagement and excellent service life
• High-torque sprung hub assembly — double sprung with spring cover reliefs for added flexibility; heat-treated components for long-term durability
• Complete kit includes pressure plate, clutch disc, release bearing, and alignment tool
• SFI Approved construction across the SPEC clutch lineup

Suitable driving applications include: Street, Drag, Drift, Road Race, Rallye, Pulling, and Autocross.

The SPEC Stage 1 delivers the performance and holding power of a purpose-built clutch while maintaining the pedal feel and engagement quality expected for daily-driven vehicles. Compatible with the original flywheel or a SPEC billet flywheel.
