Spec 99-03 Ford F250/F350 Diesel 7.3L Stage 3+ Clutch Kit

SPEC is known for making well-built clutch components that can handle more power than stock. This Stage 3+ clutch kit, part number SF133F, is built for the 1999-2003 Ford F250 and F350 trucks with the 7.3L Power Stroke diesel engine. If you're looking to upgrade your truck's drivetrain to handle increased horsepower and torque from modifications, this clutch kit is a solid option.

This Stage 3+ kit features a high-performance sprung hub clutch disc with a carbon-ceramic friction material. This combination offers a significant increase in holding capacity compared to stock, making it suitable for towing heavy loads or for trucks with engine tuning that adds substantial power. The sprung hub design helps to absorb some of the drivetrain shock, which can be beneficial in a heavy-duty application. The kit includes a high-performance pressure plate that works with the disc to provide the clamping force needed to keep the clutch engaged under demanding conditions. SPEC also includes a pilot bearing and alignment tool to help ensure a smooth installation process.

When installing this clutch kit, it's important to resurface or replace your flywheel to ensure proper clutch engagement and longevity. This kit is designed as a direct replacement for the factory clutch assembly, but it's intended for modified vehicles that exceed the stock clutch's capabilities. Be aware that a performance clutch like this may have a firmer pedal feel and a more abrupt engagement compared to the original clutch.
