Hardened pushrods are a must for any valve train upgrade on your LS based engine. These meticulously formed 5/16" chrome-moly pushrods feature .080" wall thickness & are designed for stability under high rpm use. Heat treated and finished in a black oxide finish.
7.400" is the factory length used in standard LS1, LS2, LS3, LS6, LSA, L76, L77, L99 engines, but the following few variables all have an effect on pushrod length:
Lifters - Brand, design etc.
Cam - Base circle
Heads - Deck height, rockers, valve stem height
Please be aware of this when ordering, pushrod length should be measured to determine the correct length required as incorrect pushrod length can cause engine damage.
