Q. What’s wrong with a one-size fits all clutch option?

A. Choosing the right replacement clutch is critical because as RPMs have dropped in today’s engines, the torque spikes that result are much more likely to cause torsional vibration in the drivetrain.  Some aftermarket clutches are ineffective in absorbing these torsional vibrations. The result will be resonance that can show up as damage in many different places, from gears or synchronizer parts in the transmission, to U-joints, even the clutch itself, or the flywheel or engine thrust bearings.  There are aftermarket clutch brands that sell a standard design claiming to fit a variety of torque ratings, operating ranges and cruise RPMs. They often sell their line of replacement clutches to the fleet or distributor by claiming the customer can save inventory dollars because they won’t need to stock as many replacement clutches.
