Technical overview of the 7075 alloy rear shock

This rear shock is a scale replacement designed specifically for LOSI Promoto-MX platforms and is delivered as a fully pre-assembled unit to minimise installation time. The shock body is precision machined from 7075 alloy and finished with anodizing choices to provide a durable metal surface and consistent fitment for focused suspension upgrades.

Supplied valving and hardware enable immediate installation and baseline tuning. The unit ships with shock oil pre-installed and includes multiple spring options to adjust ride height and damping response. It is advisable to secure mounting screws with thread locker to prevent fastener loosening during use.

Packing includes

  • Rear Shock Absorbers - 1pcs
  • Gold Spring - 1pcs
  • Black Spring - 1pcs

Original Name / Part No:

LOS263007

Compatible Models

  • LOSI 1/4 PROMOTO-MX MOTORCYCLE RTR,FXR-LOS06000

  • LOSI 1/4 PROMOTO-SM FXR SUPERMOTO MOTORCYCLE RTR (LOS-2272,LOS-2310)

For LOSI Promoto-MX platforms the MX112 offers a high-strength 7075 alloy option to improve suspension durability and to speed iterative tuning with pre-filled oil and selectable springs.

What mounting geometry is required for MX112?

MX112 uses the stock rear shock mounting points specified for the listed PROMOTO-MX and PROMOTO-SM models; confirm mount spacing against the Compatible Models list before fitting.

How should I approach spring selection and preload?

Begin with the middle spring supplied and set sag to manufacturer guidelines, then iterate with firmer or softer springs to fine tune midstroke support and rebound according to surface and rider mass.

Are the shocks serviceable or sealed units?

The shocks are serviceable for oil changes and seal replacement. They are shipped pre-filled to enable immediate testing, but periodic service will maintain consistent damping characteristics.

Why select 7075 alloy for suspension components?

7075 alloy provides high tensile strength and wear resistance compared with many common aluminium alloys, yielding improved dimensional stability and longevity under repeated suspension loads.
