GPM Racing 40CR Steel Main Gear 41T (M1.5) for CrossRC 1/6 EMO Xxl 6x6 (CRXXL041TS)

Precision 41-tooth main spur for EMO platforms

This 41-tooth main spur is supplied as an aftermarket replacement for CROSSRC EMO models. Manufactured from 40Cr steel with a hardened black finish, the component retains the original M1.5 metric pitch and is designed for installation without modifying gearbox geometry.

Use this spur when the factory gear shows wear or when increased durability is required for heavy loads and demanding terrain on EMO 4x4 and 6x6 configurations. The 40Cr steel construction provides improved strength while preserving the standard tooth profile for correct meshing with M1.5 pinion gears.

What material and finish are used on this spur?

The spur is made from 40Cr steel with a hardened black surface treatment to enhance wear resistance and service life under load.

Does the part change gearbox geometry?

No, it retains the original M1.5 pitch and tooth profile so gearbox geometry and mounting remain compatible with the factory layout.

How should installers verify correct mesh?

Set backlash according to the chassis manual, rotate the drivetrain to check for binding, and perform a short run to allow final settling before full power use. Write Product Review Please sign in your account before you can write any review. Sign In Close
