BUGPACK HD Chromoly Pushrods | 3/8" Cut-To-Length, .080" Wall

Achieve perfect valvetrain geometry in your high-performance air-cooled build. These BUGPACK heavy-duty chromoly pushrods are designed for custom engine configurations where standard lengths won't suffice. With a substantial .080" wall thickness, they provide the rigidity needed to eliminate pushrod whip at high RPM, especially when running aggressive cams and dual valve springs.

Crafted from 4130 chromoly tubing, each rod comes with one 60 Rockwell hardened tip pre-installed and the second tip left separate. This lets you trim the tube to the exact length required before seating the final tip, ensuring a custom fit for your specific deck height and rocker setup.

Vehicle & Engine Fitment

Frequently Asked Questions

• Why are these cut-to-length? They ship at 11.600" OAL so you can trim them to the exact length your deck height and rocker setup require, then seat the second tip.
• How much can I shorten them? They can be shortened by up to 1" to meet your specific geometry needs.
• Do both tips come installed? One 60 Rockwell tip is pre-installed; the second is left loose so you can cut to length before pressing it in.

Installation

Tech Note: A pushrod length-checking tool is highly recommended when using these. Once you have determined your optimal length, the tubing can be cut and the second tip should be pressed in (typically using a light interference fit or a specialized installation tool).
