Description
A properly engineered rocker arm is critical to maximizing valve lift and duration in your small block Chevy engine. The Elgin RK-401 delivers a solid 1.5 ratio that increases valve motion efficiency without requiring extensive head work, making it an ideal upgrade for street and racing builds seeking better top-end response. This bolt-on design includes everything needed for installation, so you can focus on tuning rather than sourcing components.
