GPI 3/8? Hardened Pushrods for LS7 - 7.750" Length - T775803-1
High-Performance Chromemoly Pushrods for LS7 Valvetrain Upgrades
The LS7's high-RPM capability and aggressive factory valvetrain demand components built for strength and precision. GPI's 7.750" 3/8? hardened chromemoly pushrods offer exceptional rigidity and durability, delivering the stability needed for upgraded cams, stiffer valve springs, and performance-minded LS7 builds. A robust .080? wall thickness and one-piece construction provide outstanding resistance to flex and fatigue.
Each pushrod is fully heat-treated and features drilled, chamfered oil holes that eliminate stress risers and help prevent cracking - ensuring reliable lubrication and long-term endurance in demanding RPM conditions.
Shorter Pushrod Length for Custom LS7 Geometry
The standard LS7 pushrod length is 7.800", but many modified setups require a shorter length to achieve proper lifter preload and rocker geometry. The 7.750" option is ideal for LS7 engines with head milling, aftermarket lifters, altered camshaft base circles, or non-stock gasket thicknesses.
To ensure pinpoint accuracy, GPI recommends verifying valvetrain geometry with the Comp Cams adjustable pushrod length checker - a simple, inexpensive tool that eliminates guesswork.
What Affects LS7 Pushrod Length?
LS7 builds vary widely, and correct pushrod length can be influenced by many factors, including:
- Block deck height
- Head deck height
- Head stud boss height
- Rocker arm brand and geometry
- Camshaft base circle size
- Lifter design, brand, or pushrod seat height
- Valve stem length
Because small variances have a big impact on preload, never assume the stock 7.800? length is correct for a modified LS7 build. Proper measurement ensures precision, performance, and reliability.

FAQs
Why does an LS7 engine need 7.750? pushrods instead of the standard 7.800??
Head milling, aftermarket lifters, camshaft changes, or gasket thickness variations often require a shorter pushrod to achieve proper preload and rocker sweep.
Are these pushrods suited for high-RPM or aggressive camshaft applications?
Yes. With their chromemoly construction and .080? wall, these pushrods provide exceptional durability and stiffness for high-RPM and high-spring-pressure LS7 builds.
