GPI 3/8? Hardened Pushrods for Gen 5 LT - 7.850" Length - T785803
Heavy-Duty Chromemoly Pushrods for Gen 5 LT Valvetrain Stability
When upgrading the valvetrain on your Gen 5 LT engine, hardened pushrods are one of the most critical components you can install. GPI's 7.850" 3/8? chromemoly pushrods deliver exceptional durability and valvetrain stability thanks to their thick .080? wall construction and rigid one-piece design - perfect for high-RPM and performance-oriented applications.
Each pushrod is fully heat-treated for maximum strength and features drilled, chamfered oil holes designed to reduce stress points and prevent cracking. Whether you're upgrading to a performance camshaft or dialing in a custom valvetrain geometry, these pushrods ensure consistent, reliable operation.
Standard-Length Upgrade for Gen 5 LT Engines
The 7.850" length is the standard pushrod size for most Gen 5 LT engines, making these hardened chromemoly pieces a direct and durable upgrade over factory components. With more aggressive cams and stiffer valvesprings becoming common in LT builds, stepping up to a stronger pushrod is essential for long-term reliability.
If your build uses aftermarket lifters, milled heads, or a camshaft with a modified base circle, GPI recommends verifying pushrod length using a Comp Cams adjustable length checker. For around $20, it ensures precise measurement and proper valvetrain geometry.
Factors That Influence Proper Pushrod Length
Pushrod length in LT engines can vary widely due to changes in components or machining. Some of the biggest factors include:
- Block deck height
- Head deck height
- Head stud boss height
- Rocker arm design and geometry
- Camshaft base circle size
- Lifter design, brand, or seat height
- Valve stem length
With so many variables in play, never assume the stock length will work - even if the combination looks similar. Measuring ensures correct preload, optimum sweep, and reliable valvetrain operation.
