Clutch Discs

What Is a Clutch Disc?

The clutch disk is part of the manual transmission, also known as the friction liner. It is between the pressure plate and the flywheel, consisting mainly of two things – the splined hub and the metal plate, where friction liners can be found. This aims to help the center splines work or engage the splines on the input shaft. Thus, the input shaft and the disk will be rotated together while the disk can still slide back and forth on the shaft.

You'll find small coil springs right between the friction disk and the splined hub of the disk clutch if you look closely. They are called a torsion spring or a damping spring. When the clutch's engagement occurs, these torsion springs absorb the vibrations or shocks that may be produced. On the other hand, the friction liner's flat coil springs are called the facing spring or the cushioning springs. They are responsible for smooth commitments and help the liner flex slightly during the initial engagement. 

The clutch disk has several protections to ensure that it is not damaged under stressful circumstances. The disk liner is made of cotton fibres, copper wires and heat-resistant asbestos.

Why Should I Upgrade My Clutch?

If your vehicle’s factory-supplied clutch starts slipping or wears out prematurely, chances are you’re not treating it right or it’s simply not up to the job you’ve assigned to it. In most cases, vehicle manufacturers equip four-wheel drives with a clutch that’s adequate for said vehicle’s intended function, such as day-to-day driving, some off-road driving and some towing.

But manufacturers rarely take into account that off-roading enthusiasts usually take things to the next level: fitting bigger tires, carrying accessories and gear, chipping the engine and fitting an exhaust, and dragging around a trailer that’s within a few grams of maximum stated towing capacity.

It is the same story when it comes to cars. Adding power and torque to your car means putting more pressure to the clutch. And the factory clutch is not rated for our desired power and torque. This is where heavy duty performance clutches pick up where the OE left off.
