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.

This kit uses our reinforced steel-backed, copper-loaded organic disc paired with a heavy-duty single diaphragm pressure plate, delivering smooth engagement you can daily drive, and the grip you need when you push it. It’s the ideal setup for stock, tuned street cars and basic bolt-on builds that want more without giving up drivability.

Like all of our sprung kits, the Super Copper features our patented fully enclosed spring retainer system, protecting you from failures that can cause serious transmission or engine damage, a problem we guarantee you’ll see with other brands.

Every kit is hand-assembled and signed off after multiple quality checks by our senior engineering team (50+ years combined experience), making sure you’re getting real, tested performance, not guesswork.

Pressure Plate Features

  • Ductile Iron Friction Plate for heat control
  • Reinforced Heavy-Duty Drive Straps
  • 4-Stage Heat Treated Diaphragm Spring for durability
  • American-Grade Rivets
  • 100% Dynamically Spin Balanced for smooth operation

Clutch Disc Features

  • Steel-Backed, Super Copper-Loaded Organic Friction Material
  • Fully Enclosed Patented Spring Retainer System for long-term protection
  • Sprung Hub for easier, smoother engagement
  • American-Grade Rivets for maximum strength
Note:
The Super Copper Series is your go-to clutch for daily-driven, tuned, or bolt-on builds. It drives smooth, handles stock-mid power, and stays strong when it heats up.

High-performance racing component. May be used in dual-purpose vehicles. Not intended as OEM replacements. This part is built with performance characteristics.

Seems to be indestructible
Color: Blue
Quality toy that seems to be indestructible to my aggressive chewer. The down side is that it's not his favorite toy because he seems to know he can't destroy it.
