SBC Long Slot Rocker Arm 3/8 Stud 1.5 Ratio Steel

The SBC Long Slot Rocker Arm 3/8 Stud 1.5 Ratio Steel from ELGIN is a precision-engineered valve train component designed for small-block Chevrolet engines. This rocker arm is essential for enhancing performance in modified engines or restoring stock configurations. It serves as a critical link between the cam follower and pushrods, converting rotational motion into the linear lift that opens and closes cylinder head valves.

The long slot design of this rocker arm accommodates pushrods with extended geometry, which is beneficial when using certain cylinder heads or camshafts that require additional clearance. The 1.5 ratio designation indicates that for every 1 degree of camshaft rotation, the rocker arm provides 1.5 units of valve lift, making it suitable for naturally aspirated small-block applications. Constructed from durable steel, this rocker arm offers superior wear resistance at the hardened tip contact point where it meets the valve stem.

This rocker arm is ideal for enthusiasts building street machines or drag racers, as it directly influences valve timing accuracy and engine breathing efficiency. Its robust design ensures reliability under elevated engine speeds or sustained loads. The 3/8 stud diameter guarantees secure mounting to your cylinder head, making it a dependable choice for various SBC applications.
