GPI 5/16? Hardened Pushrods for LS1 / LS2 / LS6 / L92 / LS3 / L99 - 7.400" Length - T740805
Durable Chromemoly Pushrods for High-RPM LS Valvetrain Upgrades
Upgrading the valvetrain on any LS-based engine demands components that can withstand serious RPM and cylinder pressure. GPI's 7.400" 5/16? hardened chromemoly pushrods deliver the rigidity and reliability required for performance builds, thanks to their stout .080? wall thickness and precision-engineered one-piece design.
These pushrods are heat-treated for increased strength and feature chamfered oil holes that help prevent cracking or stress fractures - making them a dependable choice for everything from mild cam upgrades to aggressive valvetrain combinations.
The Standard LS Pushrod Length
This 7.400" length is the standard size used in most LS1, LS2, LS6, L92, LS3, and L99 engines. While this fits many factory-style setups, every LS build is different, and even small changes in components can shift the required pushrod length. For custom builds, it's recommended to measure carefully to ensure correct lifter preload and rocker geometry.
GPI suggests using the Comp Cams adjustable pushrod length checker - a low-cost but essential tool that helps ensure you select the precise length required for your unique engine setup.
What Affects Pushrod Length?
Several component variables influence the pushrod length your LS engine may require, including:
- Block deck height
- Head deck height
- Head stud boss height
- Rocker arm design and geometry
- Camshaft base circle dimensions
- Lifter brand and pushrod seat height
- Valve stem length
Because no two LS builds are exactly alike, never assume a pushrod that worked in one engine will automatically fit another. Accurately measuring ensures ideal performance and valvetrain longevity.

FAQs
Is 7.400? the correct pushrod length for my LS engine?
7.400? is the most common OEM length for LS1, LS2, LS6, L92, LS3, and L99 engines. However, modifications such as head milling, lifter changes, or camshaft base circle variations may require a different length.
Are these pushrods strong enough for high-RPM cam upgrades?
Yes. The chromemoly material and .080? wall thickness make them ideal for high-RPM applications, aggressive camshafts, and performance valvetrain demands.
