Chevrolet Performance Stock Replacement Non-DOD Camshafts
If you're looking for a cost-effective camshaft solution to delete that pesky DOD—Chevrolet Performance stock replacement non-DOD camshafts are the answer. They're designed to work with OEM valve springs/pushrods in the DOD-equipped Gen 4 trucks. These OEM camshafts are standard equipment on non-DOD 5.3L trucks. Since they come as a single-bolt style, new timing gear won't be necessary. Just swap cams and additional DOD delete parts (sold separately) and you're ready to roll! A fairly stock truck shouldn't require dyno tuning; however, the DOD system must be disabled in ECU for proper functionality. It is advised to consult with your tuner for more information. Order the model recommended for your year/make and engine application. Additional features include: * Hydraulic roller tappet cam * Single-bolt camshaft gear attachment * Computer-controlled compatible * This is the camshaft only (other components sold separately)
