LOSI PROMOTO-MX 1/4 Aluminum 7075 Fork Tube Set by GPM MX142  [MX142]

LOSI PROMOTO-MX Fork Tube Set

This aluminum fork tube set is an RC-scale replacement designed for the LOSI PROMOTO-MX 1/4 dirt bike platform. Constructed from 7075 aluminum, the tubes serve as direct front fork replacements for the listed LOSI PROMOTO-MX models and are intended for maintenance, repair, or basic tuning tasks on the front suspension assembly.

The kit positions at the front wheel assembly and is supplied as a pair to replace both fork legs. Installation involves disassembly of the front fork housings, removal of the original tubes, and reassembly using the included rubber sealing rings to maintain axle-side sealing. Use of the correct model-specific parts and careful measurement during reassembly ensures alignment and predictable handling behavior on the RC bike chassis.

As an aftermarket hop-up, the 7075 aluminum tubes provide a stiffer, machined replacement compared with common stock materials, making them suitable where rigidity and consistent geometry are desired during setup changes or routine service. Confirm compatibility with the exact model codes listed below before proceeding with installation.

Use this GPM MX142 fork tube set when replacing worn or damaged front fork tubes on the listed LOSI PROMOTO-MX 1/4 models, and inspect seals and alignment during reassembly to maintain handling consistency.
