AXIAL SMT10 Aluminium Front/Rear Internal Shocks by GPM MJ125  [MJ125]

Aluminium Internal Shocks for SMT10

These aluminium internal shocks are made for the AXIAL SMT10 Monster Jam platform and supplied by GPM as model MJ125. They are an RC-scale replacement hop-up intended to fit SMT10 variants listed for compatibility and to serve as a tunable damping element for off-road and rock-crawling practice.

The design includes three interchangeable ball-end lengths to change the assembled damper length: 130mm (long), 125mm (medium), and 123mm (short). Internal springs use an oval profile to limit direct contact with the shock cylinder wall, and the collars that locate those springs are machined from Delrin for a smooth surface finish.

Key components described by the manufacturer include a stainless steel shock shaft and fully oil-filled assembly supplied ready to install. The shocks arrive assembled and are intended to reduce harsh rebound on rough terrain when set up appropriately for the chassis.

Installation notes: these shocks replace internal units on compatible SMT10 Monster Jam assemblies and require basic shock disassembly to change ball-end length or spring tuning; they are RC-scale parts only and should be checked for proper mounting geometry during setup.

Use these shocks to tune ride height and damping response on SMT10 Monster Jam models, verifying clearance and ball-end selection for your preferred setup before full runs.
