Aluminum Rocker Arm Kit 1.50 Ratio

The Aluminum Rocker Arm Kit 1.50 Ratio by CHEVROLET PERFORMANCE is designed for builders looking to enhance valve lift and duration in small-block Chevrolet engines. This direct bolt-on solution allows for improved performance without the need for extensive modifications to the cylinder heads. Whether you're working on a street performance engine or restoring a classic Chevy, this kit provides a cost-effective upgrade for better airflow.

With a rocker arm ratio of 1.50:1, this kit effectively increases the camshaft lift, translating a 0.400-inch cam lift to 0.600-inch valve lift at the seat. The aluminum construction reduces weight compared to traditional cast-iron rocker arms, allowing for higher RPM capabilities and quicker valve closing. This is particularly beneficial for aggressive cam profiles and high-RPM applications.

Ideal for small-block Chevrolet engines ranging from 262 to 427 cubic inches, this rocker arm kit is compatible with both hydraulic and mechanical lifters. Each arm is precision-manufactured to meet Chevrolet Performance specifications, ensuring consistent lift across all eight cylinders. This upgrade is perfect for enthusiasts looking to maximize their engine's performance potential.
