Rocker shaft - 1.1 - CB Performance

After almost Thirty years of offering our OEM forging 1.25 Rockers, we've decided to renew our tooling and forging dies. Over the years, metallurgy has improved so we contacted the Foundry Metallurgist's to see what they had to say. After much research and comparing notes, we made prototypes and performed our usual extensive testing on the dyno and in employee's vehicles, as well as a couple of well known race cars. After testing several different materials, we decided to use the same 4340 chromoly heat treat and QPQ Anti-wear coating as our 1.3 & 1.4 forged racing rocker arms. They have been in the Winner's Circle since introduction with a perfect score.

During the development of our all new 1.25 Rocker Arms, we learned that there was a demand for New High Quality Stock Standard 1.1:1 Ratio Rocker Arms as well. It's becoming difficult to find good used Rockers as most are over thirty years old and have seen better days.

Being only a slight machine change, we decided to manufacture them from the same material and finish as our 1.25:1 Rocker Arms, creating a superior part to OEM Rockers.

You now can have them in Standard 1.1:1 Ratio or the Original CB 1.25:1 Ratio! Available as Rocker Arms only, or in our complete Super Stock Rocker Arm Kits.
