Spec 61-81 MG MGA Stage 4 Clutch Kit

The SPEC Stage 4 clutch kit is built with a sprung, multi-plate design, meaning it uses multiple clutch discs to handle significantly increased power and torque. This setup is ideal for MGB owners who have modified their engines for higher performance and need a clutch that can reliably transfer that extra power to the drivetrain.

This kit is designed to be a direct replacement for your stock clutch, but it's engineered to handle more abuse. The multi-plate configuration helps dissipate heat more effectively than a single-plate clutch, which is crucial when you're putting down more power. It's a well-built option for those pushing their MGB's performance envelope.

When installing a Stage 4 clutch, it's important to ensure your entire drivetrain is up to the task. This kit is a significant upgrade, so consider other components like your flywheel and transmission to make sure they can handle the increased load.
