This Arrowmax am-931021 drive shaft is a direct replacement option for Pancar-style geardiff assemblies fitted to 1/10 and 1/12 on-road cars. Manufactured from steel as stated in the item title, the part is intended to provide a strong connection between the geardiff output and the downstream drivetrain while keeping alignment and torsional stiffness suited to tuned differential setups.
Functionally, the shaft transfers torque from the geardiff output to the gearbox or hub assemblies depending on your chassis layout, so correct fit and concentric engagement are essential. When swapping a bent or fatigued shaft, inspect the diff output splines and mating coupling surfaces for wear and ensure the shaft seats fully without side loading to avoid premature bearing or gear damage.
Installation notes: follow your chassis service instructions to remove the differential, confirm the shaft meshes cleanly with the diff output and downstream coupler, and check for free rotation before finalising assembly. Apply the recommended threadlocker grade and torque for any retaining screws, and verify there is no binding through the suspension travel specific to your model.
For workshop use, this steel V2 drive shaft is a straightforward, rugged replacement that suits builders and tuners running Pancar geardiff setups on 1/10 and 1/12 scale on-road vehicles.
