Product Details
This is the SPEC Stage 3+ Performance Clutch Kit, designed specifically for the GM F40 transmission. If you're looking to handle significantly more power than the stock clutch can manage, this kit is built for that purpose. It's a substantial upgrade for vehicles that have seen performance modifications or are intended for track use, offering a much higher torque capacity and a more direct engagement feel.
The Stage 3+ kit features a sprung, multi-plate design, which is key to its ability to handle extreme power levels. The sprung hub helps to absorb some of the shock and vibration that can come with a high-performance clutch, making it a bit more manageable for daily driving compared to a solid hub setup. The multi-plate configuration increases the surface area for engagement, allowing for better heat dissipation and a stronger grip. This clutch is built with robust materials to ensure it can withstand the demands of aggressive driving and higher horsepower applications, providing a solid connection between your engine and drivetrain.
When installing a performance clutch like this, it's important to have all the necessary components ready. This kit typically includes the clutch discs, pressure plate, and a pilot bearing, but always double-check the included parts list to ensure you have everything needed for the job. Proper break-in procedures are also crucial for the longevity and performance of any new clutch, so be sure to follow the manufacturer's recommendations closely after installation. This kit represents a significant step up in drivetrain capability for your GM F40 equipped vehicle.
