The Isky Racing Cams EZ-Roll™ lifter. You can see the small oil feed hole above the solid bearing. This assures plenty of lubrication for the wheel and pin. Side of the lifter body has been milled out to lighten the lifter. The less weight your cam lifts, the better.

This cutaway picture shows the EZ-Roll lifter and the "no-needle" construction. The special bushing distributes the load much better than the needle-bearings do and the most important thing is that you cannot send needle-bearing debris through your engine if an Isky E-Z Roll lifter should fail.

Get rid of the needle bearings, get rid of the problem
Isky Racing Cams has come up with a breakthrough roller lifter that eliminates the weakest part of the lifter, the needle bearings that the wheel rides on. The new EZ-Roll lifters are manufactured using a proprietary solid bearing that eliminates the needle bearings. With EZ-Roll lifters the load is spread out evenly on the needle-free axle and wheel area, and this means a 350% higher load rating with ZERO chance of needle bearings being involved.

There are two endurance grades of these new lifters: the EZ-Roll and EZ-Roll-X. EZ-Roll is designed for spring pressures up to 850 psi. EZ-Roll-X is designed for the radical camshafts and 900 to 1200 psi valve springs in use today. For drag racing with the big cubic inch engines the EZ-Roll-X was my choice for the Ohio Crankshaft 620” Chevy in the DRO dragster.

When I remove the Curtisbilt rockers so I can remove the pushrods and lifter I turn the engine over until that pair of rockers has lash. Doing it that way I can set the lash pretty close and move to the next pair. Occasionally you will find new lifters are a bit taller or shorter where the pushrod sits. I have found this method has never failed me. If you are a Chevy guy, you will notice these Curtisbilt rocker arms are different. No adjuster to break and two mini-main caps hold the shaft to the mount. These are without a doubt the best rocker arms I have ever used. Overkill is a good description of them, and that's a good thing on big block Chevy valve train components.
