GPI 3/8? Hardened Pushrods for Gen 5 LT - 7.775" Length - T7775803
High-RPM Chromemoly Pushrods for Precision LT Valvetrain Control
Upgrading your Gen 5 LT valvetrain requires components that can withstand high RPM, increased spring pressures, and aggressive cam profiles. GPI's 7.775" 3/8? hardened chromemoly pushrods are engineered for superior rigidity and durability, featuring a stout .080? wall thickness and a dependable one-piece construction.
Each pushrod is heat-treated for strength and designed with drilled and chamfered oil holes to prevent cracking and eliminate stress risers - ensuring reliable lubrication and consistent valvetrain operation even under extreme conditions.
Shorter Length for Custom Gen 5 LT Geometry
While standard LT engines use a 7.850" pushrod, many modified setups require a shorter length to achieve proper lifter preload and rocker geometry. The 7.775" length is ideal for builds that incorporate head milling, altered camshaft base circles, lifter changes, or custom gasket thicknesses.
For the most accurate results, GPI recommends verifying pushrod length using the Comp Cams adjustable pushrod measuring tool. At roughly $20, it's an essential tool for properly setting up any LT valvetrain.
What Determines Pushrod Length?
Several engine variables can influence the required pushrod length, including:
- Block deck height
- Head deck height
- Head stud boss height
- Rocker arm design and geometry
- Camshaft base circle size
- Lifter design, pushrod seat height, or brand differences
- Valve stem length
Because these dimensions vary from engine to engine, never assume the factory 7.850? length will provide proper preload. Correct measurement ensures optimum sweep, durability, and valvetrain stability.

FAQs
Why would my LT engine need a 7.775? pushrod?
Modified valvetrain setups - such as head milling, lifter swaps, altered cam base circles, or different gasket thicknesses - often require shorter pushrods to achieve the correct preload and rocker sweep.
Are these pushrods strong enough for high-RPM or aggressive cam profiles?
Yes. With their chromemoly steel construction and .080? wall, these pushrods are designed to handle high RPM, heavy spring pressures, and aggressive camshafts with excellent durability.
