Aluminium internal dampers for SMT10 Monster Jam

These aluminium internal shocks are designed for AXIAL SMT10 Monster Jam platforms and carry the model number MJ125. Built as an aftermarket hop-up, they fit the SMT10 variants listed in the compatibility box and provide tunable damping for scale off-road and rock-crawling use.

The kit includes three interchangeable ball-end lengths to alter assembled damper length: 130mm (long), 125mm (medium), and 123mm (short). Springs are oval-profile to reduce bearing contact with the shock cylinder, and the collars that retain those springs are machined Delrin for low friction and consistent positioning.

Key parts include a stainless steel shock shaft and a fully oil-filled assembly provided assembled for immediate installation. Correct setup will help reduce sharp rebound on rough tracks when matched to your chassis weight and tyre choice.

Installation notes: these internal shocks replace stock units in compatible SMT10 Monster Jam setups and require simple disassembly to swap ball-end lengths or change spring rates. Verify mounting geometry and clearances before full running.

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 these units to refine ride height and damping balance on SMT10 Monster Jam kits, checking ball-end selection and clearance during setup to suit your preferred terrain.

Do MJ125 shocks fit AX90055 and AX90057 without modification?

They are made for SMT10 Monster Jam models listed as AX90055 and AX90057, but you should confirm ball-end selection and shock length against your chassis mounts before final fitment.

How do I change the assembled shock length?

Disassemble the shock and swap the supplied ball-end options to the desired length, then reassemble with the original spacers and screws to retain seal integrity.

Are the shocks delivered filled with oil?

Yes, the shocks are supplied oil-filled and assembled for immediate use, though you can service them later to change oil weight or replace seals.

What routine maintenance is recommended?

Inspect Delrin collars and shaft for wear, refresh oil after heavy running, and retorque fasteners to preserve consistent damping performance.
