Hardened pushrods are a must for any valvetrain upgrade on your LS based engine. These pushrods feature .080" wall thickness & are designed for stability under high rpm use.
These one-piece pushrods are heat-treated and feature oil holes that are drilled and chamfered to prevent stress fractures and cracks. These 5/16" pushrods are available in many lengths. Standard LS1/LS2/LS6/L92/LS3/L99 length is 7.400"
If your building a custom valvetrain setup you might consider purchasing the TSP adjustable pushrod measuring tool. It's a perfect tool for making sure you get exactly the right pushrod length for your application. A large number of variables are involved in determining the correct length pushrod for your application.
Pushrod length is affected by any of the following:
Block deck height
Head deck height
Head stud boss height
Rocker arm brand/design
Cam base circle size
Lifter design/brand/pushrod seat height
Valve stem length
Don't assume anything when determining the right pushrod for your new engine. A pushrod that fits one engine may not necessarily work in another. Any number of items can be different on your engine, requiring you to use a different pushrod length.
