X-Maxx Heavy Duty 55T Steel Spur TXM055TS replacement by GPM  [TXM055TS]

Durable 55T steel spur for X-Maxx gearboxes

The TXM055TS is a 55-tooth steel spur offered as an aftermarket replacement for TRAXXAS 1/8 X-Maxx models. Its hardened construction is aimed at improving resistance to tooth chipping and wear in demanding, high-torque running conditions.

As the primary spur meshing with the pinion, correct backlash and secure fastening are vital. After fitting, manually rotate the drivetrain to ensure gears engage smoothly and recheck torque on the mounting hardware before powered testing.

Practical notes: switching to steel can make the drivetrain feel a touch heavier and louder compared with plastic, but it greatly enhances tooth durability under aggressive use. Consider revisiting pinion size and ESC cooling strategies after the change to keep components running safely.

Use this steel 55T spur for a robust replacement that preserves original fitment on the X-Maxx, and always confirm gear mesh and mounting torque when installing.
