SBC Sport Comp Shaft R/A Kit 1.60/1.50 Ratio

The SBC Sport Comp Shaft R/A Kit 1.60/1.50 Ratio from T AND D MACHINE is a precision rocker arm assembly designed specifically for small-block Chevrolet engines. This kit is ideal for performance builders and engine rebuilders who are looking to enhance valve lift and optimize valve timing geometry. It is suitable for various applications, including street performance engines, weekend track cars, and competition platforms.

The 1.60/1.50 ratio specification indicates the leverage ratios for the intake and exhaust rocker arms, respectively. This means that the intake rocker arm multiplies the camshaft lift by 1.6, while the exhaust rocker arm has a ratio of 1.5, balancing scavenging efficiency without excessive valve spring loads. T AND D MACHINE rocker shafts are crafted from high-quality materials and undergo precision machining to ensure uniform bearing surfaces and minimize wear.

This rocker arm kit is particularly beneficial for those looking to upgrade their valvetrain components to support higher RPM operation and aggressive cam profiles. It is designed to enhance horsepower delivery, fuel efficiency, and overall engine reliability, whether under boost or naturally aspirated conditions. Builders can trust this assembly to meet the demands of performance and racing applications.
