Rockstar Viper 1-4 Disc Clutch Friction Disk - 8-Tab, .123"-.130" - Go Kart Racing

Transferring maximum horsepower to the asphalt demands the fade-free engagement of the Rockstar Viper 8-Tab Clutch Friction Disk, a staple upgrade available at our kart store for serious competitors. Engineered as the original OEM standard for Viper One, Two, Three, and Four-disc clutches prior to mid-2020, this 8-tab friction disk delivers the aggressive bite demanded by high-output race engines.

Unlike softer aftermarket alternatives that glaze over during intense heat cycles, the Rockstar disk utilizes a slightly harder, wear-resistant friction compound. Measuring between .123" and .130" in thickness, it ensures optimal air gap tolerances within your clutch basket, preventing parasitic drag and unexpected power drops out of the apex. Whether you are tuning your engagement RPM for a tight sprint track or managing slip on a high-speed oval, this disk provides the consistent lock-up necessary to shave tenths off your lap times.

Drivetrain Synergy & Track-Proven Performance

Serious racers know that a winning chassis is a sum of its parts. Just as you wouldn't compromise on master cylinder brake parts or run subpar brake fuel, your clutch assembly requires authentic, track-proven materials. While you might be browsing our latest engine oil sale or even looking for a new go kart frame for sale, refreshing your clutch pack with OEM Rockstar disks is the most cost-effective way to restore peak drivetrain efficiency.
