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.

Our billet aluminum rocker holddown sets are fully machined from 6061 T-6 aluminum, blue anodized for good looks, and include genuine ARP 12 point hardware (bolts and washers.)
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.
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.
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.
Finally, a reasonably priced quality rocker arm setup for Edelbrock Victor, and other Big Block wedge heads which use .650" offset intake rocker arms!
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 rocker arms (8 intake arms in special .650" offset and 8 exhaust arms in standard offset) 2 4340 hardened thick wall shafts, 16 adjusters and 16 12 point locknuts. This version is supplied in a 1.5 ratio. 1.6 ratio is available as a separate part number.

These rocker arms DO NOT require using our .650" thick spacers (part #113-1018) because the extra thickness of the special offset rockers takes the place of the thick spacers. We DO recommend 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.

We also offer our .650" offset rockers as one pair. Can be used for service replacement purposes, or order 4 pair to convert a standard set of rockers to .650" offset intakes. 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.)

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 rockers, or as an upgrade for use with other companies rocker arms. Diameter is the same a standard factory shaft.
Shown here are our Rocker Shaft Spacer Rings, used in between each pair of rocker arms. These are approx. .200" thick, and should be used only with stock (stamped steel type) rockers. These are refinished original factory pieces. Sold in a package of 4. For a stock application, this is enough for one head, so use 2 packages per engine. (8 rings total.)
We also offer our rocker arms in pairs (one left hand and one right hand) for service replacement purposes. These sets include 2 replacement adjusters and locknuts also. 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.)

These are the 12 point rocker adjuster jam nuts supplied in our roller rocker kits. Offered as a convienance for lost originals, service replacement purposes, etc. Sold 1 per package. Use 16 for a complete engine set.
These are the rocker adjusting screws supplied in our roller rocker kits. Offered as a convienance for lost originals, service replacement purposes, etc. Sold 1 per package. Use 16 for a complete engine set.
Limited availability WHILE SUPPLIES LAST only!! Offered here is a package of cleaned and refinished original factory Chrysler bolts and retainer plates to bolt ONE rocker shaft down to ONE cylinder head. Fits all big block applications which use cast in rocker stand (1964 and later). For a factory application, this is enough for one head, so use 2 packages per engine. These normally come with the original factory bolts, but in some cases we may subsitute new grade 8 bolts instead, which will be stronger than the originals.
