3Racing MST-17/LB Performance Aluminium Upper Suspension Arm for Team Losi Mini LST  [MST-17/LB]

Race-Oriented Aluminium Upper Arm for Mini LST

Engineered to support competitive setups, the 3Racing MST-17/LB aluminium upper suspension arm provides a low-deflection replacement for stock components on the Team Losi Mini LST. Its machined profile helps retain alignment under lateral loads and aids precise roll centre behaviour.

Tuned Fit and Consistent Geometry

The 3Racing MST-17/LB is shaped to match OEM mounting points so shock and hub alignment remain consistent. The stiffer aluminium construction reduces compliance in the suspension link, enabling finer adjustments to camber and toe without masking suspension response.

Installation and Setup Notes

Installation follows standard upper arm replacement steps and is suitable for experienced tuners and club-level racers. After fitting, expect improved repeatability during setup changes and more direct feedback from the front end when refining handling balance.
