Description

GPI Chromemoly Hardened Pushrods In Your Choice Of Lengths – Set of 16!

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

COMP Cams- Hi-Tech Pushrod Length Checking Tool (7702-1)

$33.95
Add to cart

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.

    Asked by Rich on February 8, 2022 9:40 pm
    A Honestly that's all factory stuff, you could use a 7.400 and be perfectly fine. Realistically you want to measure zero lash then add the length for your desired preload if you want to fine tune length.
