THREE MOST POPULAR GRINDSA bolt-in cam for all RPM ranges.
Something for everyone.

S&S® set out to develop a new group of bolt in cams for 2007-up big twins. The three design targets were low end torque for touring, peak horsepower and a cam that would offer the best possible combination between torque and horsepower. The 551 emerged as the touring cam and the 583 is a great over all cam. The proven 585 posted the best results for peak horsepower.

551 Torque Cam

Optimized for a 2007-up 96 to 106 CID touring bike with slip-on mufflers and 9.0 to 10.0:1 compression
Best bolt-in cam available for dressers
Pulls hard from idle to 4000 rpm.

583 Midrange Cam

Optimized for use as a great over-all cam in the Softail®/ Dyna® lines, but can be used in any 2007-up big twin model.
Provides strong low end torque and horsepower that you can really feel.
Strongest from 1500-5000 in a Softail/Dyna application.

585 Horsepower Cam

Optimized for a 2007-up Softail or 2006-up Dyna 96 to 106 CID with slip-on mufflers, high flow air filter and 9.0 to 10.5:1 compression.
Great results from 3000-6000 rpm.

HERE’S HOW IT WORKS

ONE
Each of the two exhaust cam lobes are equipped with a spring loaded compression release lobe on the “heal” of the cam at the point where the valve would normally be fully closed.

TWO
The lobe holds the exhaust valve open slightly at cranking speed. This releases some of the compression, making the engine much easier to crank.

THREE
Once the engine starts, and rpm increases, the compression release lobe is centrifugally retracted and the engine runs normally, with full compression, and without any loss in performance. This allows a stock starter and battery to start nearly any engine.

Reduces cranking compression – easier on starting system!
