Precision CNC aluminium internal shocks for SMT10

This MJ125 aluminium internal shock assembly is engineered for AXIAL SMT10 Monster Jam platforms as an upgrade hop-up. Designed for hobbyists and modifiers, the unit provides adjustable damper length and serviceable internals to tune damping characteristics for scale off-road performance.

The assembly includes three ball-end length options to set the finished shock to 130mm, 125mm or 123mm. Oval-profile internal springs reduce sidewall friction and the Delrin spring collars offer precision locating with minimal wear. The shaft is stainless steel for corrosion resistance and straightness under load.

Shocks are supplied fully oil-filled and assembled for immediate installation. Service-accessible design allows oil weight changes, seal replacement and ball-end swaps to optimise rebound and compression for specific vehicle mass and tyre configuration.

Installation note: intended to replace internal shocks in compatible SMT10 Monster Jam units. During setup check mounting geometry, articulation limits and ball-end orientation to ensure correct kinematics for your application.

Packing includes

  • 3X16 Stainless Steel Button Head Screw - 2pcs
  • 3X14 Stainless Steel Button Head Screw - 2pcs
  • Aluminium Collars - 2pcs
  • Pelrin Shim - 2pcs
  • 3MM Lock Nut - 2pcs
  • Middle Point 22MM Ball Ends Installed with 5.8X7.4 Balls - 2pcs
  • Middle Point 12.5MM Ball Ends Installed with 5.8X7.4Balls - 2pcs

Compatible Models

  • Smt10 Monster Jam AX90055
  • AX90057

Use the MJ125 shocks when precision damping and repeatable setup are required for SMT10 Monster Jam applications; confirm part orientation and clearances before full-power runs.

What tolerances should I check during installation?

Verify ball-end seating and mount spacing for lateral play, check shaft runout visually, and ensure the assembled length matches your suspension geometry to avoid binding.

How do I service the damping internals?

Disassemble by removing the cap and shaft assembly, drain existing oil, inspect seals and springs, then refill with the chosen oil weight and reassemble using the supplied hardware to factory torque values.

Which ball-end is recommended for heavy setups?

For heavier vehicle setups the longer 130mm option may be appropriate to preserve suspension travel and avoid over-compression; validate with static sag and articulation tests.
