Front, Center and Rear Outdrive Replacement

This aftermarket outdrive is a direct-fit RC replacement for ARRMA platforms, machined from 4140 medium carbon steel to resist wear in high-load drivetrain positions. It installs in front, center, or rear differential housings and keeps CVD or dogbone shafts engaged while transmitting torque reliably.

One end of the outdrive is extended by 2mm to reduce the chance of dogbones slipping out under hard driving, and the 4140 steel balances toughness with dimensional stability to help maintain smoother rotation under load. This part is focused on durability and drivetrain consistency rather than altering gear ratios or handling.

Fitment follows the vehicle's stock differential procedure, using the same mounting points and retaining hardware as the factory outdrive. Check mating CVDs, bearings, and retaining clips for wear during replacement to ensure proper fit and rotation.

Packing includes

Will this replace the stock ARRMA outdrive directly?

Yes, this MAK039SA outdrive fits the same differential positions and uses the factory retaining hardware on the listed ARRMA models.

Does the 2mm extension need extra shims or spacers?

No additional spacers are required; the extra 2mm helps keep dogbones or CVDs seated under aggressive loads without added hardware.

What should I inspect after installation?

After fitting, check mating CVDs, bearings and retaining clips for wear, then run the drivetrain at low speed to confirm smooth rotation.
