FAQ - How To Properly Measure An S-Cam?

With many different sizes of S-Cams for heavy duty trucks, how do you know which size is right for your truck? In order to find the right sized s-cam for your heavy duty truck, you’ll need to take three different measurements.

  1. First, you’ll need to measure the length of the camshaft by measuring from just below the cam head until the beginning of the lock ring groove.
  2. Next, determine the style of the head comparing it to the styles found here and determining the head width.
  3. Finally, measure the diameter of the spider and spline to solidify which s-cam you should get.

It’s very important to make sure your s-cam is properly serviced so you don’t experience a failure and put yourself, and others around you, in danger.
