Technical overview of the aluminium adapter and 55T steel spur

The MJ1555T upgrade pairs a precision aluminium spur adapter with a 55T steel spur intended for AXIAL SMT10 based drivetrains. It is written for hobbyists seeking a mechanically rigid, lower mass adapter combined with a durable steel gear to reduce tooth wear under higher loads.

The set supplies the mounting screws, 4mm lock nut, Pelrin collar and steel posts required to install the adapter and spur into the existing assembly, maintaining stock shaft spacing and mounting geometry for direct fitment on compatible chassis.

From an engineering viewpoint the aluminium adapter provides a concentric interface and reduced rotational inertia, while the 55T steel spur offers improved abrasion resistance. Careful pinion-to-spur backlash adjustment and clearance checks with the gearbox and suspension are recommended during installation.

Packing includes

  • 3X6 Stainless Steel Button Head Screw - 3pcs
  • 4MM Stainless Steel Lock Nut - 1pc
  • Pelrin Collars - 1pc
  • Steel Posts - 1pc

Compatible Models

  • SCX10 II AX90047
  • SMT10 Monster Jam AX90055
  • AX90057
  • SSCX271555T

Install MJ1555T where improved spur durability and a rigid, well-centred adapter are required to keep consistent mesh and reduce wear on AXIAL SMT10 derived drivetrains.

Which chassis layouts are confirmed compatible

Refer to the compatible models list in the product box; the adapter is designed to match the mounting patterns indicated for SCX10 II and SMT10 variants listed.

Recommended mesh procedure

Set a fine, even backlash across the tooth face, secure the adapter hardware incrementally, then recheck mesh under static and suspension-loaded positions to avoid dynamic binding.

Material benefits and maintenance

The aluminium adapter reduces rotating mass and maintains concentricity while the steel spur provides greater wear resistance; keep the assembly clean and inspect for tooth wear periodically.
