Description

When you’re rebuilding a disc gang or replacing worn axle shafts, you need parts that’ll hold up to the torque and side loads that come with cutting through heavy residue and hard ground. This 1-1/8 inch square axle shaft measures 40.25 inches in usable length and gives you the precision fit your Case IH disc needs to keep cutting straight and true.

What You’re Getting

Precision-machined 1-1/8 inch square shaft that eliminates wobble and blade chatter
40.25-inch usable length with 2-3/4 inch threaded section for secure nut engagement
Heat-treated steel construction that handles the constant flexing of field work
Direct replacement design—no modifications needed for proper fit

Built for Real Farm Work

This axle fits Case IH disc harrows including models 122, 132, 350, 370, 3800, 3850, 475, 480, 485, 496, 501, 596, 760, 770, and RMX790. Whether you’re running a compact utility disc for food plots or a heavy tandem for primary tillage, this axle provides the backbone that keeps your disc blades properly aligned and cutting efficiently.

Made to Last

Disc axles take a beating from rocks, stumps, and the constant vibration of cutting through varying soil conditions. This shaft is manufactured from quality steel with proper heat treatment to resist bending and wear at critical stress points. The square profile provides maximum surface contact with bearings and eliminates the play that causes premature blade wear.

Good to Know

When replacing axle shafts, it’s a good time to inspect your disc bearings and spacers for wear. The threaded end uses a 1-1/8-7 nut—make sure to torque it properly to prevent loosening during operation. A light coat of anti-seize on the threads makes future maintenance much easier.
