The Texas Speed 5/16" Chromoly Pushrod is sold individually for Gen III and Gen IV LS engines, which makes it easy to replace one damaged pushrod, fine-tune lengths across a valvetrain or buy sixteen to build a full set. Each pushrod is one-piece heat-treated chromoly with a .080" wall, and Texas Speed designs them for stability under high rpm and the heavier valve spring loads that come with an aftermarket camshaft.
Oil holes are drilled and chamfered so there are no sharp edges to start a crack. Lengths from 7.175" to 7.575" are available in .025" steps, and Texas Speed lists 7.400" as the standard length for LS1, LS2, LS6, L92, LS3 and L99 engines. Since block and head deck height, head stud boss height, rocker arm design, cam base circle, lifter seat height and valve stem length all affect the required length, Texas Speed recommends measuring with an adjustable pushrod length checker before ordering.

Ordering Options
Select the pushrod length from the Length option when ordering. This listing is for one pushrod; order a quantity of 16 for a complete set. Texas Speed also sells the same 5/16" pushrods as a set of 16 under part number TSP-7xxx-16.
Note: Never assume pushrod length carries over from one engine to another. Verify the length on the assembled engine before ordering.
FAQ
What engines does the Texas Speed 5/16" single pushrod fit?
It fits Gen III and Gen IV LS engines that use 5/16" pushrods, including the LS1, LS2, LS6, L92, LS3 and L99 and the 4.8L, 5.3L, 6.0L and 6.2L truck engines, in the length selected at ordering.
Is this a single pushrod or a set?
This listing is for one pushrod. A V8 needs sixteen, so order a quantity of 16 for a complete set, or buy individual pushrods to replace a damaged one or to try a different length.
What length pushrod does a stock LS use?
Texas Speed lists 7.400" as the standard length for LS1, LS2, LS6, L92, LS3 and L99 engines. Aftermarket cams, lifters, heads and rockers can change that, so the length should be verified with an adjustable pushrod checker.
What are these pushrods made of?
They are one-piece heat-treated chromoly pushrods with a .080" wall thickness and drilled, chamfered oil holes, built by Texas Speed to stay stable under high rpm and stiffer valve springs.
Why does Texas Speed recommend hardened pushrods for a cam swap?
Stiffer valve springs and higher rpm put more load on the pushrods, and factory pushrods can flex or fail under those conditions. Hardened chromoly pushrods keep the valvetrain stable and are considered a must for any LS valvetrain upgrade.
