Set of sixteen one-piece 6.300 × 5/16 in. chromoly pushrods with 0.080 in. walls for guideplate valvetrains.
Speedmaster 1-254-003 is a set of one-piece, heat-treated 4130 chromoly pushrods. The 6.300 in. length, 5/16 in. diameter and 0.080 in. wall are intended for measurement-based performance valvetrain combinations, including guideplate applications.
Application / fitment
The product does not have one universal engine application. Pushrod length must be selected after accounting for block and head height, lifter design, camshaft, rocker arms, machining and required lifter preload.
- V8 engines requiring sixteen 6.300 in. pushrods
- valvetrains using guideplates
- performance and rebuilt engines with non-standard geometry
Do not order solely by engine make or displacement. Required length can change after head/block machining or changes to the camshaft, lifters and rocker arms.
