|Item||Diaphragm spring, 480lbs|
'98 and later Big Twin models 6 Studs Style Clutch
(except '13 and later Big Twin Model with A&S Clutch, 3 Studs Style)
Note : The clutch spring pressure is directly related to the pressure spot of the retaining ring. There are at least 4 different type of springs in the market. The 480 lbs spring installed with an aftermarket aluminum retaining ring will not give you the full 480 lbs of clutch pressure for performance.
