TRX4M Centre Driveshaft Set Front and Rear Medium Carbon Steel TRX4M037S by GPM  [TRX4M037S]

Front and rear centre shaft upgrade

An aftermarket centre driveshaft set for 1/18 TRX4M models, supplied as non-OEM replacement parts. Manufactured from medium carbon steel to increase torsional strength and to better cope with heavier motors and longer suspension throws commonly used on scaled trail rigs.

Application: these shafts transfer power through the chassis centre to the front and rear differentials, influencing drivetrain durability and transmission of torque under high articulation. They are ideal when you need greater load capacity or the stock shafts are showing signs of fatigue.

Installation tips: the package contains the small screw pins for mounting and only basic tools such as hex drivers are required. Always confirm correct spline engagement and coupling fit on your TRX4M transfer case before final tightening to avoid binding at full articulation.

A practical centre driveshaft option for TRX4M 1/18 enthusiasts looking to strengthen the driveline without extensive modification.
