What is an SMF?

SMF stands for Single Mass Flywheel as opposed to the popular two piece Dual Mass Flywheel designs that are fitted to many cars and light commercial vehicles as original equipment.

Dual mass technology is intended to give smooth tick over and drive characteristics for mainly turbo-diesel applications.  Unfortunately, these complex multi-component units have been plagued with reliability issues, often failing very early in their life expectancy.  Like for like replacements are very expensive and do not guarantee to be any more reliable than the original unit.

The SMF replacement reverts to the original solid flywheel technology that has stood the test of time over many decades.  With these replacement kits the damping system is included as part of the clutch plate design rather than in the flywheel as with dual mass units.

This will give reliable motoring at a much reduced cost to that of replacing the DMF unit.
