GPI 3/8? Hardened Pushrods for Gen 5 LT - 7.700" Length - T770803
High-Strength Chromemoly Pushrods for Custom Gen 5 LT Valvetrain Builds
Any time you upgrade the valvetrain on a Gen 5 LT engine, hardened pushrods become a must-have component. GPI's 7.700" 3/8? chromemoly pushrods are engineered to withstand the increased demands of aftermarket cams, high-RPM operation, and stiffer spring loads. Built with a stout .080? wall thickness and a one-piece construction, these pushrods deliver exceptional rigidity and reliability.
Each pushrod is fully heat-treated for durability and features drilled, chamfered oil holes that eliminate stress risers and help prevent cracking. These enhancements make them a dependable upgrade for any LT performance build.
Shorter Pushrod Length for Precision LT Geometry
The stock Gen 5 LT pushrod length is 7.850", but performance combinations often require a shorter length to achieve correct lifter preload and rocker arm geometry. The 7.700" length is ideal for builds affected by head milling, different lifter designs, altered camshaft base circles, or custom gasket stack variations.
To ensure accuracy, GPI recommends verifying pushrod length with the Comp Cams adjustable pushrod measuring tool - a low-cost but essential tool for proper LT valvetrain setup.
What Determines Pushrod Length?
Several engine factors impact the required pushrod length, including:
- Block deck height
- Head deck height
- Head stud boss height
- Rocker arm brand/design
- Camshaft base circle size
- Lifter brand, design, or pushrod seat height
- Valve stem length
With so many variances, never assume the standard 7.850? length will work. Proper measurement ensures ideal preload, valvetrain stability, and long-term component life.

FAQs
Why would my Gen 5 LT engine need 7.700? pushrods?
Modified builds such as those with milled heads, aftermarket lifters, changed cam base circles, or altered gasket stack heights often require shorter pushrods to maintain proper preload and rocker geometry.
Are these pushrods suitable for high-RPM or heavy valve spring applications?
Yes. With chromemoly steel construction and a .080? wall thickness, these pushrods are engineered to handle high RPM, aggressive camshafts, and increased spring pressure.
