Three Most Popular Grinds

A 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!
