Longer lasting JS radiused cam – a drop in kit. We regrind your original flat lifters to a 1-1/8″ radius, use your original pushrods for Commando, Atlas/Domni

You must send us your lifters to be reground to 1-1/8″ radius (either late flat or early cut corner lifters are OK). Longer lasting than the stock flat lifter setup. Uses the same cams as our JS radiused cams for lightweight lifters as shown above but you use your original pushrods (more info). Available with asymmetric profiles.  Commando cams fit either 750 or 850.  Stage 3 and 4 cams require light weight lifters with a 7/8″ radius (see my complete cam kits).  Stock lifters will not radius to 7/8″.
