Overview
STREET/TRACK APPLICATIONS (OCCASIONAL TRACK USE – CIRCUIT / TIME ATTACK / ROAD RACING)
The Super Copper Kit brings a new level of performance to the street and track. It’s built with the highest copper content you’ll find in any organic clutch on the market — giving you a better grip than OEM, better heat tolerance, and more consistent performance on and off the track. Backed by a reinforced steel plate and a copper-loaded organic facing, it’s designed to hold more power without giving up smooth street drivability.

Upgrade your vehicle’s drivability and performance with a premium single-disc clutch kit engineered for street enthusiasts, tuned daily drivers, and lightly-modified builds. This kit combines a reinforced steel-backed, copper-loaded organic disc with a heavy-duty single-diaphragm pressure plate, delivering smooth, predictable engagement and the increased holding power you need when you push your setup. Perfect for stock cars, street-tuned vehicles, and basic bolt-on applications, it offers superior grip without sacrificing OEM-like comfort.
Built with reliability in mind, this system features a patented fully enclosed spring-retainer design that protects against spring failures known to damage transmissions and engines — a critical advantage over many competing clutch brands. Every unit is hand-assembled in the USA using locally sourced materials, continuing a 60-year tradition of craftsmanship. Each kit undergoes multiple quality checks and is individually signed off by seasoned engineers with over 50 years of combined experience.
For drivers needing even more durability, our Stage 2 configuration delivers up to 110% increased holding capacity using steel-backed full-face Kevlar® friction material. This offers exceptional heat dissipation, long service life, and incredibly smooth engagement — ideal for daily driving, stop-and-go traffic, track-day beginners, off-road use, and naturally aspirated or low-boost builds with bolt-ons, cams, nitrous, or basic headwork. Despite the performance gains, pedal effort remains close to stock for unmatched drivability.
Each complete kit includes the clutch disc, pressure plate, throwout/release bearing, pilot bearing or bushing (when applicable), and an alignment tool — everything needed for a proper installation.
Break-in Procedure 500 street miles / Keep RPM’s under 4500, no more than half-throttle, no boost (if applicable)
