Welcome, and thank you for considering us for your performance diesel needs. There are quite a few changes for 2014. First we are offering free shipping on all web orders over $50. Also, we have added nine new profiles to improve airflow for your specific application, whether you are towing 30,000lbs in the mountains, drag racing or sled pulling. For all out competition engines check out our new three pattern cams with different profiles on cylinders one and six to fix the flow imbalance they have. With over 20 different Cummins cams in stock, and ready to ship, and many other competition grinds not listed, we have the widest selection of cams to meet your specific needs from 1,500-6500RPM! Feel free to call us if you have any questions about specifications, pricing and availability on any of our products. For international orders, please call the office.

Warning: not all 24valve springs are created equal…. recently we have started seeing other companies market products that are called 110lb 24 valve springs, when in reality they have 117-119lb of seat pressure and almost 250lb nose pressure at .320 lobe lift. Also, they are designed as an entry level spring for a dodge neon, but are re-boxed and sold to the diesel crowd. This spring can cause major lobe wear to anything over a stock lift cam. ALL of our cams have more than stock lift.

For comparison, our 103lb springs have 102-104lb seat pressure and 180lb nose pressure with the 188-220. By running anything other than our 103lb 24v springs with our cam, you nullify the warranty we offer. If you run a cam with more than .320″ lobe lift and anything other than the 103lb spring you run the chance of experiencing coil bind before maximum valve lift is achieved.
