GPI 5/16? Hardened Pushrods for LS1 / LS2 / LS6 / L92 / LS3 / L99 - 7.425" Length - T7425805
High-Strength Chromemoly Pushrods for LS Performance Builds
When you're upgrading the valvetrain on your LS platform, hardened pushrods are an absolute must. GPI's 7.425" 5/16? chromemoly pushrods deliver the durability, stiffness, and oiling reliability needed for high RPM stability in both street and race applications. Built with a robust .080? wall thickness, these pushrods ensure consistent performance where weaker factory components fall short.
Each GPI pushrod is manufactured as a one-piece, heat-treated design with chamfered oil holes to reduce stress points and prevent cracking. Whether you're refreshing a worn engine or assembling a custom valvetrain, these pushrods provide the confidence and durability required for aggressive camshaft profiles and demanding LS builds.
Precision Length for LS Applications
The 7.425? length option supports many common LS combinations, though measuring for correct valvetrain geometry is always recommended. Standard LS1, LS2, LS6, L92, LS3, and L99 engines typically use 7.400? pushrods, but custom builds may require alternative lengths depending on your specific components.
If you're assembling a unique setup, GPI recommends using the Comp Cams adjustable pushrod length checker - an inexpensive tool that ensures you dial in the exact measurement needed for your engine. With so many variables at play, correct length selection is essential for peak performance and long-term reliability.
What Determines Proper Pushrod Length?
Pushrod length can vary significantly based on component selection and machining tolerances. Factors that influence length include:
- Block deck height
- Head deck height
- Head stud boss height
- Rocker arm brand/design
- Camshaft base circle size
- Lifter design and pushrod seat height
- Valve stem length
Because no two builds are identical, always verify length rather than assuming factory dimensions will apply. A pushrod that works for one engine may not be correct for another - even with similar parts.

FAQs
Do I need to measure pushrod length even if my engine is mostly stock?
Yes. Even small changes such as head milling, lifter brand, rocker geometry, or gasket thickness can affect required pushrod length. Measuring ensures proper preload and valvetrain operation.
Are these pushrods suitable for high-RPM or aggressive camshafts?
Absolutely. The chromemoly construction and .080? wall thickness provide the rigidity needed to maintain stability at high RPM and under aggressive camshaft profiles.
