Did you know that about 97 percent of all diesel pickup trucks sold in the US for the last 20 years come with an automatic transmission? It’s clear that most truck drivers prefer vehicles with an automatic transmission over a manual one for various reasons. However, this doesn’t mean that there are no drivers left with a manual transmission. Some drivers are still using a manual transmission, and when it comes to this, picking the right clutch usually makes all the difference in their overall driving experience.

In this article, we will share what a clutch entails and which type to select for your manual transmission vehicle:

Three main factors impacting the clutch

In a nutshell, a clutch is a mechanical device that transfers the rotational power from the diesel engine to the wheels. It connects two or more rotating shafts—one coming from the engine and the other turning the wheel. Ultimately, it is a vital part of a truck’s machinery where the engine generates power all the time, with some parts constantly rotating and the wheels not continually spinning. 

When it comes to how much torque a clutch can transfer without slipping, here are three factors to consider:

• Surface area: This refers to how many square inches of friction materials are in contact with the flywheel.
• Clamping force: This pertains to how hard the pressure plate squeezes.
• Coefficient of friction: This identifies what it’s made out of and how strong the grip of the material is.

What clutch to look for

Let’s take a closer look at some of the most popular types of clutch for a manual transmission vehicle, as follows:

• Organic Clutch Kit: Most trucks leave the manufacturing factory with a woven organic part. This type has a smooth engagement, high resistance to wear, and mid-level torque rating. Should it become damaged or need a replacement, simply replace it with another kit.
• Ceramic Single Disc Clutch: It’s more likely that you will slip the Organic clutch once you’ve performed some basic performance upgrades, such as intake, high flow exhaust, and a tune. When confronted with this problem, having a Ceramic Single Disc Clutch can be your best option. This consists of copper, iron, bronze, and graphite that are considered effective for a higher coefficient of friction. It can also endure so much heat and hold more power than an organic part. However, just be wary of losing a smooth engagement that you’re used to with your organic disc.
• South Bend Full Ceramic Clutch: This part has a higher power capacity, which is perfect for those wanting to boost their vehicle’s horsepower. This type has a torque rating of 1,100 lb.ft. in a single disc application, and works great even when your truck performs towing and hauling functions.

Conclusion

At this point, you now know what types of clutches to choose from for your manual transmission truck. Apart from these three, there are other various types you can use in friction compounds, such as metallic blends, Kevlar, bronze, and even graphite. 

Ultimately, your selection all boils down to how the manufacturer employs balance engagement, heat resistance, longevity, and power capacity for your manual transmission. Be sure to choose the one that works perfectly for your manual transmission truck!
