Hardened pushrods are a must for any valvetrain upgrade on your LS based engine. These TSP chromemoly 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 Comp Cams adjustable pushrod measuring tool. At only about $20 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 fi ts 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.
