History of Colt Cams Diesel Camshafts
Colt Cams has been in business making High-performance Camshafts for almost 30+ years now. After 30+ years in the camshaft grinding business you can imagine how many cams Colt Cams has worked with!
Colt Cams has extensive knowledge and expertise that was obtained through years of hard work and extensive testing. Colt Cams has a wide field of expertise in the research, development and testing of High Performance Camshafts. Colt Cams produces high performance camshafts for a wide variety of motors and has now developed and tested over 2,200 different profiles.
This extensive knowledge base of High Performance Diesel Camshafts is decades ahead of companies that merely copied a camshaft profile and called it their own.
Remember, it's far cheaper to do it right the first time so buy from the original manufacturer of Cummins High Performance Diesel Camshafts: Colt Cams.

Tech Tips for Colt Cams Diesel Camshafts
In this image, you can see the effects that a worn camshaft has on the lift if it is worn by 0.020" then it will have that much less total lift. To calculate the lift you measure the width of the lobe and subtract that from the height. By removing that same 0.020" from the entire perimeter of the lobe, keeping the same center-line, the entire lobe is smaller, but the effective lift machined to 0.400". That 0.020" now can be made up with the extra preload the factory gives hydraulic lifters, or on a solid lifter valvetrain you just reset your clearances.
This regrinding can process be performed upon camshafts that are not worn out, to achieve more lift for a performance application by removing a greater amount from the base circle. Keep in mind the tip of the lobe cannot exceed the height of the bearing journal on cams that slide through the block or head. So even when grinding blank billet stocks to a performance camshaft, the base circle quite often is smaller than stock. On cradle type bearing caps we still need to be cautious of too much lift and stock base circle for clearance reasons.
Because of slight variances in the different camshaft models, we find it is safer to use our customer's factory core. Using our customer's core will not only lower the costs but result in a better quality product for some applications. High-grade OEM camshafts contain extremely high-grade metal used in factory cams, especially with certain import cams like Honda and Acura camshafts.
