GPI 5/16? Hardened Pushrods for LS1 / LS2 / LS6 / L92 / LS3 / L99 - 7.375" Length - T7375805
Premium Chromemoly Pushrods for Custom LS Valvetrain Builds
For any LS-based performance build, hardened pushrods are essential to maintaining valvetrain stability - especially at elevated RPM. GPI's 7.375" 5/16? chromemoly pushrods provide exceptional stiffness and durability, thanks to their reinforced .080? wall thickness and precision-crafted one-piece construction.
These pushrods undergo a full heat-treating process and use chamfered, drilled oil holes that reduce stress points and help prevent premature wear or cracking. They are engineered for aggressive camshafts, aftermarket valvetrain components, and high-RPM performance where factory pushrods fall short.
Ideal for Custom LS Geometry Adjustments
While the standard LS pushrod length is 7.400", unique engine builds often require shorter or longer pushrods to achieve correct valvetrain geometry. The 7.375" length is commonly used in setups where machining, lifter design, or cam base circle changes necessitate a slight reduction in length.
For maximum accuracy, GPI recommends using the Comp Cams adjustable pushrod length checker. At around $20, it's one of the smartest tools you can add to your engine-building arsenal, ensuring proper preload and roller sweep across your specific combination.
What Changes Pushrod Length Requirements?
Many factors influence the ideal pushrod length for an LS engine. Variations may come from:
- Block deck height
- Head deck height
- Head stud boss height
- Rocker arm design and geometry
- Camshaft base circle diameter
- Lifter brand, style, or pushrod seat height
- Valve stem length
Because these tolerances vary across engines and component brands, never assume a standard pushrod length will work. Measuring the exact length ensures proper valvetrain operation, reduced wear, and improved performance.

FAQs
Why would I need a 7.375? pushrod instead of the standard 7.400??
Machining changes, aftermarket lifters, camshaft base circle differences, or rocker arm variations may require a slightly shorter pushrod to achieve correct lifter preload and valvetrain geometry.
Are these pushrods suitable for high-RPM or performance camshafts?
Definitely. The chromemoly construction and reinforced .080? wall make them ideal for high-RPM stability and demanding camshaft profiles.
