GPI 5/16? Hardened Pushrods for LS1 / LS2 / LS6 / L92 / LS3 / L99 - 7.350" Length - T735805
High-Strength Chromemoly Pushrods for Precision LS Valvetrain Control
When upgrading the valvetrain on any LS platform, hardened pushrods are essential to maintaining stability and durability - especially with aftermarket cams or high-RPM use. GPI's 7.350" 5/16? hardened chromemoly pushrods offer exceptional rigidity thanks to their .080? wall thickness and robust one-piece construction.
These pushrods are heat-treated for added strength and built with drilled, chamfered oil holes to reduce stress concentrations that can lead to cracks or failures. They're engineered for performance builds where factory pushrods simply don't provide enough strength or consistency.
Shorter Length for Custom LS Applications
While most LS1, LS2, LS6, L92, LS3, and L99 engines use a 7.400" pushrod from the factory, certain combinations require a shorter length. The 7.350" size accommodates setups with altered preload requirements due to upgraded lifters, head milling, camshaft base circle changes, or rocker geometry differences.
To achieve ideal valvetrain geometry, GPI strongly recommends using the Comp Cams adjustable pushrod length checker. At around $20, it's an inexpensive tool that eliminates guesswork and helps ensure perfect fitment for your build.
Factors That Influence Proper Pushrod Length
Small changes in your engine build can significantly alter the pushrod length required. Common variables include:
- Block deck height
- Head deck height
- Head stud boss height
- Rocker arm design or brand
- Camshaft base circle size
- Lifter brand, type, or pushrod seat height
- Valve stem length
Because each of these factors can vary from one engine to the next, never assume one-length-fits-all. Measuring ensures proper preload, optimal valvetrain motion, and long-term reliability.

FAQs
Why would I choose a 7.350? pushrod over the standard 7.400? LS length?
Custom valvetrain setups often alter preload or geometry. Machining, lifter design, or camshaft base circle changes may require a shorter pushrod to maintain correct valvetrain alignment.
Can these pushrods support high-RPM or aggressive camshaft combinations?
Absolutely. The chromemoly material and .080? wall thickness provide the stiffness needed for high-RPM operation and demanding performance builds.
