Introduction

4-PadSprung RaceDisc by ACT

4228205 is a 4-pad spring-centered race disc made with high quality, ceramic friction materials. The engagement is harsher, but shifting is faster. The heavy duty torsional dampening springs are stronger, in most cases, than standard springs and are provided in the best sizes and spring rates to suit the application. The race disc features a heat-treated spring steel drive plate and is well-suited for the smaller disc sizes in smaller engines.

Features

• Feel: Aggressive engagement, quick shifts, OE to mild gear rattle
• Life: Premium ceramic friction materials provide moderate wear rates and high heat tolerance
• Quality: Utilizes wraparound spring windows, thicker retainer stampings and a heat-treated, spring steel drive plate to provide support, reduce stress concentrations and increase strength and reliability
• Recommended Use: Recommended for race use only
• ACT Difference: High burst strength and holds 28% more torque than typical organic materials
