Metal axles and clamping wheel hexes

Arrma Typhon Grom MEGA 380 · ARA2106

This package replaces the front driveshafts and rear stub axles while adding metal hexes that clamp onto the wheel axles. It retains the separate rear dogbones, so it is a wheel-end rebuild rather than a complete metal drivetrain.

Exact brushed-edition manufacturer offering; retained bearing, hub and rear-dogbone condition still matters. No measured service-life improvement verified.

Installation notes

  • Use ARA311198 for this ARA2106 target. The Mojave Type B package and the Granite/Typhon package are separate identities; similar kit inventories do not establish cross-fitment.
  • One pack includes two preassembled front universal joint driveshafts, two rear stub axles, four wheel hexes, four locking grub screws, four drive pins and four M4 nuts.
  • Retain the serviceable original wheel bearings, steering hubs, rear hubs, suspension hinge hardware, separate rear dogbones, differential assemblies and center driveline. The kit does not include a new rear dogbone pair.
  • Fit the supplied wheel-end pins, hexes, grub screws and nuts in place of the removed wheel-end hardware. Confirm free rotation, full steering and suspension travel after assembly. Installation torque and threadlocking directions are not specified on the product page.
  • Keep the original supported brushed 2S electronics, radio, battery/charger, motor, spur/pinion and wheels. A 12mm hex does not by itself verify every aftermarket wheel offset, diameter or clearance.
  • The tradeoff is parts cost and wheel-end disassembly. Replace worn parts as needed; metal material alone does not establish a measured durability gain.
