BTR 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

ARP LS CAM BOLTS 

End your camshaft timing worries! High-quality cam sprocket bolts have increased preload clamping force to ensure positive timing gear register. Their increased material strength overcomes valvetrain harmonics and stress. These cam bolts have a reduced head size that makes installation and removal easier.
