GPI 3/8? Hardened Pushrods for LS7 - 7.725" Length - T7725803-1
Heavy-Duty Chromemoly Pushrods for High-Performance LS7 Engines
For LS7 engines running upgraded cams, stiffer valve springs, or higher RPM than stock, hardened pushrods are essential for maintaining valvetrain stability and preventing flex. GPI's 7.725" 3/8? chromemoly pushrods deliver exceptional rigidity thanks to their precision-built one-piece construction and durable .080? wall thickness.
Each pushrod is fully heat-treated for maximum strength, with drilled and chamfered oil holes to prevent stress fractures and improve oiling - critical for reliable valvetrain operation under demanding conditions.
Shorter Pushrod Length for Custom LS7 Valvetrain Geometry
The factory LS7 pushrod length is 7.800", but many modified setups require a shorter length to achieve the correct lifter preload and rocker geometry. The 7.725" length is ideal for LS7 builds with changes such as head milling, altered cam base circles, non-OEM lifters, or varying gasket stack height.
To ensure perfect valvetrain geometry, GPI recommends using the Comp Cams adjustable pushrod length checker. At about $20, it's one of the smartest and cheapest tools you can use during any LS7 build.
What Affects LS7 Pushrod Length?
Several machining and component variables determine correct pushrod length for an LS7 engine, including:
- Block deck height
- Head deck height
- Head stud boss height
- Rocker arm brand/design
- Camshaft base circle size
- Lifter design, brand, or pushrod seat height
- Valve stem length
Because each build is unique, never assume the stock 7.800? length will provide correct preload - measurement is always required when any component differs from OEM specs.

FAQs
Why would an LS7 engine require 7.725? pushrods?
Head milling, aftermarket lifters, changes in camshaft base circle, or gasket stack variations often reduce preload requirements - necessitating a shorter pushrod like 7.725?.
Are these pushrods strong enough for high-RPM LS7 performance builds?
Yes. With chromemoly steel, .080? wall thickness, and heat-treated construction, these pushrods deliver the durability and stiffness needed for aggressive camshafts and sustained high RPM.
