S&S is providing clutch options for users of its own engines and where S&S or other tuning parts installs are leaving the stock Harley clutch in need of some help.
 |
| Variable pressure clutch |
The S&S Cycle variable pressure clutch is said to provide up to 40 percent more additional pressure, for stronger clutch engagement, than the stock part. Designed to work like a lock-up clutch, the new S&S variable pressure clutch, for use on ’98-onward Big Twins with a six-stud clutch hub, increases the strength of engagement as the rpm increases.
It fits behind a stock derby cover and primary cover, but does not fit ‘13 and later CVO and Tri-Glide, ‘15 and later Ultra Limited Low and Electra Glide Classic Low models with new H-D Assist and Slipper clutch (three-stud clutch hub). Non-stock derby cover (including any special or ‘03 Anniversary cover) and three-hole derby covers may require a derby cover spacer.

| Transmission mainshaft bearing race |
The new transmission mainshaft bearing race by S&S is said to not ‘walk’ on the transmission mainshaft under high torque loads preventing damage to its seal, output gear and output gear bearing.
It features an extra step on the inside diameter that acts as a stop on the transmission mainshaft. When the race is pressed onto the shaft, the step will not allow the race to move inward toward the mainshaft seal. The S&S bearing race is can be used on ’06-’07 and 2010-onward Big Twins.

| Heavy duty diaphragm spring |
Completing the clutch upgrade options from S&S Cycle is a new heavy duty diaphragm spring for ’98-and up Big Twins. With 380lbs of pressure it is said to be 25 percent stronger than stock, offering the same pressure as a Screamin’ Eagle heavy duty clutch spring. The new diaphragm spring is compatible with both S&S and stock VP clutches.
