Heavy Duty Chromoly Pushrods
These are our Heavy Duty Pushrods made from 1/4" Diameter 4130 Chromoly.
The stock pushrods flex at higher RPM causing loss of valve lift. These are a great upgrade for anyone with HD springs running without a governor. They are a MUST for those with cams and/or 1.3:1 rockers.
Achieving correct Valvetrain geometry is necessary to a reliable performance engine.
There are 3 Length options:
Cut-To-Length - You will need to measure your required pushrod length (depends on deck height or block and head, rocker arms, cam, etc) and cut it to size. They are 8" Long and ready to be cut down to the size you need and have the ends pressed in.
6.74" - These are the OEM 440/460 pushrods and they will fit most engines with an unmilled head and shaft rockers.
6.50" - These are the OEM length GX390/420 Clone pushrods and they will fit most engines with a stock to .100" milled head and standard stud rockers.
