CSK Coil & Diaphragm Clutch Spring Kits:

Complete Engine sets of stack height controlled friction plates featuring the EBC unique alloy particle impregnated clutch facings that prevent burn up or slippage.

It is important to note that you cannot change the basic shape of these springs to gain any performance advantage but what you CAN do is buy an EBC Brakes CSK kit which has slightly thicker winding material and delivers 10 – 15% more clamp pressure.

• This can help reduce clutch slip or fast clutch wear on your machine.

Clutch springs fall into two basic types:-

Coil springs

These are spiral wound springs using four to eight pieces per set, made from heat treated high carbon steel and come in various shapes and sizes, delivering differing spring tensions depending on the size of the bike and the horsepower of your engine.

Diaphragm Springs

These are dish shaped flat steel pressure rings and there are normally only one or two in a bikes engine

Note:- All springs get tired and should be replaced at every engine rebuild or clutch overhaul
