BRIAN TOOLEY 5/16" 7.400" CHROME-MOLY PUSHRODS SET OF 16 

Hardened pushrods are a must for any valvetrain upgrade on your LS based engine.  These BTR 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. 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 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.
