Ford F Series Diesel Pickups

You are at the point where the clutch on your Ford F Series Diesel pickup has worn out and you're looking at your options. You may have modified the engine/exhaust or added a chip to increase horsepower. Perhaps you tend to tow a lot of heavy loads and need something that won't slip in the higher gears? You've seen a lot of different options from several different companies and have gotten a lot of different advice from different sources. Get's a little confusing, doesn't it?

We created the following article with links to the different model years in hopes that it can help you make an informed decision. Please do not hesitate to call us if you would like us to make a recommendation based on your truck and its' intended use.?

Some of these vehicles came equipped from the factory with a Dual Mass Flywheel. The problem with the Dual Mass Flywheel in these pickups is that it is limited by the OE engine torque capacity (ETC) and would tend to wear out in a very short period of time - often less than 40K miles when hauling heavy or after installing engine upgrades. In a direct response to the failure rate of the Dual Mass Flywheel, Valeo, the original OE manufacturer, engineered a Solid Flywheel Conversion Kit. The Solid Flywheel Conversion kit quickly became very popular with truck owners and also allowed for flexibility in engineering clutch options with increased torque capacities.

Quick Note: The only downside to converting to a Solid Flywheel is that the engine vibration that diesels tend to produce no longer gets absorbed by the flywheel. The engine vibration is transferred to the transmission and causes "gear rattle". This is only noticeable when the truck is at a stop, in neutral, with the clutch pedal out. As soon as the clutch pedal is applied, the vibration goes away. This is a normal occurrence when doing a solid flywheel conversion. It does not increase gear wear and can be safely ignored. It can be minimized by using additives.

Woven Organic Disc Clutch Kits

Recommended Use: As a Daily Driver plus Hauling/Towing on asphalt.
Not intended as for racing applications where a high heat high friction ceramic material is required.

Woven organic is the friction material of choice when the goal is to maintain the smooth engagement of the original clutch. Woven Organic Clutch Kits are recommended if your truck is a daily driver and/or you are using your truck to tow on paved surfaces. The increase in torque is accomplished by using a higher clamp load pressure plate. The step up in clamp load only can increase pedal pressure in a range of 10-25%. High clamp kits are designated by a suffix number (i.e. .2, .3, .4, .5) without a letter included which indicates the disc has organic linings.

Kevlar Disc Clutch Kits

Recommended Use: As a Daily Driver plus Hauling/Towing on and off highway.
Not intended as for racing applications where a high heat high friction ceramic material is required.

Kevlar lining is the friction material of choice when the goal is to maintain the smooth engagement of the original clutch with a moderate increase in friction level while also having the ability to gain up to three times the life of the original lining. Kevlar Disc Clutch Kits are recommended if your truck is a daily driver and/or you are using your truck to tow lighter loads. Works well both on and off-road.

Ceramic Disc Clutch Kits

Recommended Use: Farming, Forestry/Logging, Construction Sites, Full-Time Snow Plows, and Light Racing.

Ceramic buttons are a high heat high-torque friction material which tends to, once broken in, have a short slip period when engaged. Ceramic disc clutch kits work well for pickups that are intended for off-road use where the dirt allows for tire slippage minimizing the quick engagement nature of the disc. When used on asphalt, a Ceramic button disc will tend to chatter upon engagement in first or reverse when getting started from a dead stop, and is most noticeable when under load or towing. This is caused by the driver feathering the clutch to try to control engagement. Due to the short slip period of this material, this feathering creates a constantly fluctuating engagement cycle with the flywheel and pressure plate. Our Ceramic button discs are engineered to minimize chatter, and are best used when the engagement is done normally. Several high clamp load pressure plate options providing a step up in torque are available for these model years. This step up in clamp load only applies a small 10-15% increase in peddle pressure from the previous stage. High clamp kits are designated by a suffix number (i.e. .4C, .5C) with the "C" indicating the disc is Ceramic.
