Front, Centre and Rear Differential Outdrive

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

The outdrive has a 2mm extended end to reduce the chance of dogbones disengaging during aggressive driving, and the material choice balances toughness with dimensional stability to promote smoother rotation under heavy load. This upgrade is aimed at improving drivetrain durability and consistency rather than altering gear ratios or handling characteristics.

Installation follows the vehicle's standard differential procedure and uses the same mounting points and retaining hardware as the factory component. Inspect mating CVDs, bearings and retaining clips for wear during replacement to ensure correct fit and rotation.

Packing includes

  • Diff Outdrive - 2pcs

Will this improve durability over stock parts?

Yes, the 4140 medium carbon steel construction of MAK039SA is chosen to better resist wear in high-load drivetrain positions compared with typical stock materials.

Is any extra tooling needed for installation?

No special tooling is required beyond standard diff service tools; the part mounts using the same retaining hardware as the original outdrive.

How often should I inspect these under heavy use?

Under hard running, inspect mating CVDs, bearings and washers regularly and check for any signs of wear or play after each session.
