LS Engine 3-Piece Push Rods Stock Length 7.400

The LS Engine 3-Piece Push Rods Stock Length 7.400 by PROFORM delivers OEM-spec valve train geometry for enthusiasts building or refreshing LS-platform engines. These push rods are essential valve train components that transmit camshaft lift through the rocker arms to open and close intake and exhaust valves with precise timing and lift characteristics. Built for street, strip, and track applications, this three-piece design provides the durability and dimensional accuracy required for high-rpm operation on LS1, LS2, LS3, and other Gen III/IV small-block LS variants.

PROFORM engineered these push rods to maintain factory tolerances while delivering consistent performance across the full rpm range. The 7.400-inch stock length specification ensures drop-in compatibility with standard LS cylinder heads and factory rocker arm geometry, eliminating the need for shims or geometry modifications. The three-piece construction—featuring hardened steel construction throughout—resists flex under load and minimizes deflection that can cause valve timing drift or excessive clearance variation. This design is particularly critical at sustained high-rpm operation, where inferior push rods can induce harmonics that degrade valve control and compromise reliability.

Mechanics and engine builders routinely specify PROFORM push rods for stock restoration, performance upgrades, and race engine assembly where valve train integrity is non-negotiable. Whether you are refreshing a tired LS engine block, transitioning from carbureted to fuel-injected LS power, or validating your existing valve train components, this stock-length set delivers the precision fit and durability needed for thousands of reliable miles. Installation is straightforward on any LS platform; simply drop them into the factory push rod tunnels during top-end assembly and torque rocker arms to spec. For serious LS enthusiasts demanding OEM-correct performance without compromise, PROFORM's three-piece push rods remain the industry standard.
