GPI 3/8? Hardened Pushrods for Gen 5 LT - 7.725" Length - T7725803
Heavy-Duty Chromemoly Pushrods for High-RPM Gen 5 LT Engines
When building or upgrading a Gen 5 LT engine, hardened pushrods are critical for ensuring proper valvetrain control - especially with performance camshafts, stiffer valve springs, or extended high-RPM operation. GPI's 7.725" 3/8? chromemoly pushrods are engineered with a robust .080? wall thickness and a durable one-piece construction to deliver superior strength and stability.
Each pushrod is heat-treated for maximum durability and features drilled, chamfered oil holes designed to eliminate stress risers and prevent cracking. These improvements make them an excellent choice for LT engines experiencing increased valvetrain loads.
Shorter Pushrod Length for Custom LT Geometry
Although most factory Gen 5 LT engines use a 7.850" pushrod, many performance combinations require a shorter length. The 7.725" option is ideal for builds where valvetrain preload must be reduced due to head milling, lifter variations, camshaft base circle changes, or different gasket stack heights.
For the most accurate and reliable results, GPI recommends measuring with the Comp Cams adjustable pushrod length checker. At roughly $20, it ensures proper preload and rocker sweep for your specific combination.
What Influences LT Pushrod Length?
Several mechanical and machining variables affect the correct pushrod length for your LT engine, including:
- Block deck height
- Head deck height
- Head stud boss height
- Rocker arm design and geometry
- Camshaft base circle size
- Lifter design, brand, or pushrod seat height
- Valve stem length
With so many variables in play, never rely on the factory 7.850? length without measuring. Proper preload and valvetrain geometry are essential for performance and component longevity.

FAQs
Why would my LT build need 7.725? pushrods?
Changes such as head milling, aftermarket lifters, altered cam base circles, or non-standard gasket thicknesses may require a shorter pushrod to achieve proper preload and rocker geometry.
Are these pushrods suitable for high-RPM or heavy spring pressure applications?
Yes. These chromemoly, .080? wall pushrods are designed to handle the demands of aggressive LT camshafts, stiff springs, and elevated RPM ranges.
