The Centerforce II Clutch Kit CFT500500 is designed for the 1999–2007 Chevy Silverado 1500 and GMC Sierra 1500 with the 4.8L or 5.3L LS-based V8 and NV3500 or M5 manual transmission. If you've swapped a manual into your GMT800 or your factory clutch is worn from towing, this kit brings back crisp, reliable engagement.

This 11-inch kit is rated at 350 ft-lbs of torque and uses Centerforce's centrifugal weight pressure plate to boost clamping by 50% at higher RPM without a heavy pedal at idle. The organic-metallic friction disc provides smooth daily driving engagement while holding firm under load. The complete set includes pressure plate, disc, release bearing, pilot bearing, and alignment tool. Pedal effort is about 20% heavier than stock.

The CFT500500 is particularly effective in LS-swapped GMT800 trucks where the factory dual-mass flywheel has been replaced with a solid conversion unit. The additional clamping force prevents shudder when a stock-style clutch can't fully engage the solid flywheel surface. The organic material provides enough give to prevent shock-loading the NV3500's input shaft.

Your Silverado manual transmission deserves a clutch that handles LS torque. Get the Centerforce II CFT500500 and enjoy every shift. Order now.

Frequently Asked Questions

What is the clamping load rating on this Centerforce clutch kit?

The Centerforce clutch kit uses patented centrifugal weights that increase clamping force by 30 to 60 percent over stock as engine RPM rises, while maintaining light pedal effort at low RPM. The dual-friction disc combines an organic material for smooth engagement on one side with a metallic compound on the other for high heat resistance and holding power. This clutch kit typically handles 400 to 600 foot-pounds of torque depending on the specific application, making it ideal for modified street and strip vehicles.

Will this Centerforce clutch kit fit my vehicle's stock flywheel and pressure plate?

The Centerforce clutch kit includes a pressure plate, clutch disc, and release bearing engineered as a matched set for your specific vehicle, transmission, and flywheel combination. It is designed to work with the factory flywheel surface as long as the flywheel is within specification for flatness and step height. For optimal performance, Centerforce recommends resurfacing or replacing the flywheel during installation to ensure proper break-in and full clamping surface contact.

How does the pedal feel compare between the Centerforce II and Dual Friction clutch kits?

The Centerforce II clutch kit offers a moderate 15 to 25 percent increase in clamping force over stock with a slightly firmer pedal feel, making it suitable for daily drivers and light performance use. The Centerforce Dual Friction kit provides a more significant 30 to 60 percent increase in holding power while maintaining a surprisingly manageable pedal effort thanks to the centrifugal weight system. Both kits use Centerforce's patented weight system that multiplies clamping force at higher RPM without requiring a heavy pedal at stoplights.

What type of disc material does the Centerforce clutch kit use?

The Centerforce clutch kit utilizes a dual-friction material combination that bonds a smooth-engaging organic compound to a high-coefficient metallic compound for superior heat dissipation and holding power. The disc hub is spring-cushioned to dampen drivetrain shock during engagement, reducing stress on the transmission input shaft and differential. This material formulation allows the disc to handle sustained high-RPM operation without glazing, making it suitable for track days and aggressive street driving.

Does the Centerforce clutch kit include a pilot bearing and alignment tool?

Most Centerforce clutch kits come with a new pilot bearing or bushing, release bearing, and sometimes a clutch alignment tool to simplify installation. The included release bearing is matched to the pressure plate's diaphragm spring height for proper throwout travel and clutch disengagement. Always verify the contents of your specific Centerforce part number because some kits are designed for vehicles with a bushing-type pilot rather than a bearing.

How long does a Centerforce clutch typically last in a daily-driven performance car?

A Centerforce clutch installed in a daily-driven performance car typically lasts 40,000 to 60,000 miles with normal driving habits, though aggressive launching and repeated hard shifts can reduce that range. The dual-friction disc is designed to resist glazing better than organic-only discs, so it handles occasional track use without immediate wear. Proper break-in of 300 to 500 miles of gentle driving is essential to maximize clutch life and ensure the flywheel and disc surfaces mate correctly.
