Aluminum Roller Rockers/shafts - 1.5 Ratio - New

Our brand new aftermarket aluminum roller rockers are an unbelievable value! Made out of aircraft quality certified 2024 aluminum alloy, these arms are formed using a hydraulic extrusion process under 1500 tons of pressure, giving these arms an incredible 60,000 PSI tensile strength! They are fully CNC machined, and finally anodized for additional durability and corrosion protection. These sets come complete with 16 arms, 2 shafts, 16 adjusters and 16 locknuts, and are available in 1.5 and 1.6 ratios.

Our rockers use extra heavy duty NSK licensed large fulcrum needle bearings between the arm and the shaft (shown in the "view additional images" button) so friction is reduced (and therefore additional horsepower is gained) between the arm and the shaft, as well as between the valve and the the roller tip. These bearings are rated up to valve spring loads of 600 pounds open pressure (which includes most cams in the .500-.600" lift range.) Be careful not to confuse these with some other rockers on the market which offer a much cheaper and easier to manufacture design of a solid aluminum rocker which offers the roller tip, but runs the aluminum of the rocker body directly against the shaft, a setup which produces much more friction and wears the arms out extremely quickly. Since these feature the roller bearing, and a super hard roller tip hardened to 60 on the Rockwell C scale, these will work just as well on a high mileage street car as they do on a drag only setup. They also feature pressurized oiling of the pushrod ball/cup area, and a generous valve spring clearance relief in the underside of the body (shown in the "view additional images" button)

When purchasing these rocker arms, we strongly recommend using our .650" spacers listed separately (part #113-1018) to locate the arms on the shafts, and our shim package (part #105-1018) to center each arm exactly over each valve tip, and set the endplay, which should be about .015"-.030". For shaft holddowns, we recommend using our aftermarket billet aluminum holddowns listed separately (part #200-1032.) These are what is shown in the above pictures. Please note again they ARE NOT INCLUDED automatically with these sets.

Rocker Shaft .650 Spacers (Set of 8) - New
As a compliment to our aluminum roller rocker sets, we recommend these .650 wide spacers which fit between each pair of intake and exhaust rockers and keep the rockers located where they are supposed to be on the shafts.

Rocker Shaft .015 Shims (approx 36) - New
With any performance type aftermarket roller rockers, it is necessary to "set up" the valvetrain. Because of different cylinder heads/tolerances/past machine work, etc, the exact positioning of the valves can vary slightly. A large part of setting up a performance valvetrain involves using shims to position the rocker arms at the correct point on the shaft so that the roller tip is exactly centered or aligned over the valve stem tip. We offer these packages of special .015" thick rocker shaft shims for this purpose. They are supplied in packages of approx. 36 per package. We have found some engines to use only one package, but many engines will require two packages, depending on how much "free space" the washers must fill and how tight you wish to adjust the rockers (we recommend .015"-.030" of play.) Use these in conjunction with the correct spacers and shaft holddowns to position the rockers where they need to be. We recommend using these with all of our aftermarket roller rockers, as well as rockers from other aftermarket companies. Not needed with stock stamped type rockers.

Rocker Shaft Shims (pkg. of 30)
A large part of setting up a performance valvetrain involves using these shims to check and adjust the wear pattern of the rocker tip. This can be thought of as how the rocker "wipes" across the valve face and back. Adding, and/or subtracting these shims underneath the rocker shafts allows you to setup this spec. the way you want it. We offer these shim packages for this purpose.

Trick Flow Rocker Holddown Conversion Kit
We offer this 12 point performance bolt upgrade kit for using TRICK FLOW heads with our 200-1032 Billet Aluminum Rocker Holddown kit. Normally rocker hold downs will use 6 short bolts and 4 long ones, however Trick Flow heads were re-designed to use all 10 short bolts. So, we have sourced the additional four 12 point bolts required, and we offer them as a separate kit which can be purchased to use our 200-1032 rocker holddowns with Trick Flow heads. Includes 4 bolts, use one package per engine. Washers are not included, they are supplied with the 200-1032.

Aluminum Roller Rocker - Single Left Hand - 1.5 Ratio
We also offer our rocker arms as individual pieces for service replacement purposes. These include replacement adjusters and locknuts. These can also be used to allow you the flexibility to run mixed ratios, such as 1.6 on the intake and 1.5 on the exhaust (or vice versa.) This is the left hand rocker, which means as you are looking at the two rockers of a specific cylinder, this rocker would be on the left side, which means the pushrod on this rocker would be offset to the RIGHT. See picture for example.

These are also a good option which will allow you the flexibility to run mixed ratios, such as 1.6 on the intake and 1.5 on the exhaust (or vice versa.)

Replacement 4340 Super Heavy Duty Rocker Shafts (pair) - New
Super heavy duty .165" wall thickness rocker shafts that are INCLUDED with (and developed specifically for) our roller rocker arms. Thinwall, light duty rocker shafts supplied with "the competitions" roller rocker sets are shown on the left for comparison. In addition to the much heavier wall thickness, our HD shafts are made from solid 4340 steel. This helps the shafts to maintain perfect roundness under extreme loads, and allows the holddowns to be tightened to the proper torque without distorting or "ovaling," which is a common problem with the thinner shafts. We sell these heavy duty shafts separately as a service replacement part for our roller rockers. Diameter is the same as a standard factory shaft, however due to the position of the oiling holes, these WILL NOT work with factory stamped rocker arms. One package includes TWO shafts.

Freeze Plugs - Rocker shaft - Package of 4 - New

Sold in a package of 4. Use one package per engine. Cheap insurance. Works with stock (factory type) shafts only. Will not work with aftermarket (thick wall) shafts.
