Full Line of Options
Whatever your goals are, Elgin has a rocker arm to fit your needs. We manufacture stamped steel stock or long slot rocker arms with stock or higher ratios. Guide rail options are available for Small Block Chevy Applications and roller tip versions as well. In-house heat treat operations allow us to offer these in a hardened “Nitro” version. For the best in durability and wear resistance, “Black Ice” cryogenically frozen rockers are the choice for most racers. Both offer the “stock appearance” in classes where rules dictate.
Elgin’s stainless steel full roller rockers with upgraded roller trunnions have proven themselves to be the preferred option for high performance engines that demand extreme reliability.
Select the Best
Selecting the correct rocker arm for your specific application and performance expectations is a critical
decision to achieve your goals.
If you are doing a stock rebuild, a stock rocker arm is the best choice. Choosing a rocker arm with a long slot
and increased ratio can be detrimental and possibly cause engine damage due to excessive valve lift. Valve to piston contact, valve spring coil bind, retainer to valve stem seal or guide and retainer to rocker arm contact are also other common issues that will lead to premature failure and engine damage.
In a performance build with a higher lift camshaft, there are several options available. A rocker arm with a long slot is recommended to avoid stud to arm contact. To reduce wear and fatigue on the valve stem, a roller tip rocker arm is the correct choice. For increased horsepower and faster response while simultaneously reducing valve tip wear and deflection, a full roller rocker arm is recommended.
