This 1.6:1 ratio rocker kit is designed for the IND I-E-H1-1K Indy/Edelbrock heads.
CNC'd Aluminum Rockers. Includes Spacers, Shims & chamfered Shafts.
We designed these rockers for Chrysler engines specifically. They are not something that was "close and changed slightly to fit. They were not just "good enough for Dodges", as others are. We have developed our rockers after years of putting up with other rockers and their various shortcomings. They are made in the USA, exclusively for Hughes Engines. There are several important features that distinguish our premium rockers from the garden-variety rocker you find from everyone else.
These rockers are CNC machined. This means that once the correct dimensions are determined and programmed in, all parts are identical.
Our rockers have a revised oil system that gives a positive oil flow to the pushrod cup at all angles.
Our rollers and axle shafts are larger (i.e. stronger) and reduce rolling friction
They do not use needle rollers on the shaft. Mopars® have a full pressure oil supply to the rocker and shaft interface area, and do not need the rollers. On the other hand, stud mounted rockers are not positively lubricated with pressurized oil and must have rollers to live. Magnum rockers are not pressure lubricated and will require rollers on the shaft. Yes, just like the Chevy's!
Our big block rockers will clear 1.625" diameter valve springs without cutting or grinding. (When the geometry is correct)
We do not anodize the rockers for a reason. If anodizing material is left in the bore, the wear surface is compromised when in contact with the hardened rocker shaft. Honing out anodized material is a machining operation that would add cost and leaves a finish no better than a straight bored finish.
We tumble finish our rockers which is not as flashy as the "pretty ones" like the "tuner guys" on TV. The appearance is more compatible with those you would see on Pro-stock and NASCAR engines. That's good enough for us.
The roller position and rocker design are unique features. The rollers travel in the center of the valve stem tip and the path is narrower than other "will fit" rockers. Most other rocker arms do not properly position the roller on the valve tip.
Our rocker kits come with our popular, modified oiling shafts, spacers and shims. Properly assembled and shimmed, each pair of rocker will have less than 0.015" total side clearance. This provides exceptional oil control and a valve train that is much quieter than all other systems.
For those customers requiring severe duty rockers, we can supply these rockers cryogenically treated. This process will increase the strength and durability of the rockers 2 to 3 times. For additional information about cryogenic treatment refer to our tech article.
Kits come shipped with complete, detailed installation instructions.
Compatible with hydraulic, mechanical, or roller camshafts.
Machined to clear larger diameter valve springs.
