The Arrowmax AM-930001 is a front differential one-way unit made for MUGEN MRX5 and MRX6 platforms. It provides a drag-assist engagement profile aimed at modifying front traction and steering characteristics while leaving the chassis architecture intact.
Focused on setup refinement, this one-way changes how power is transferred through the front diff under cornering loads, allowing drivers to adjust front-end behaviour and turn-in balance. It is supplied as a drop-in replacement for the front one-way assembly on qualifying MUGEN models and suits 1/8-scale electric on-road or touring applications that use these chassis.
Fitting the unit requires normal diff access and everyday RC workshop tools; inspect the donor bearings and seals during service and torque fasteners to specification to prevent unwanted play or binding. Fine-tuning results from selecting matching diff oils and complementary diff settings elsewhere rather than from the one-way alone.
Fit this one-way as a tuning element to fine-tune front traction and steering balance on MRX5/MRX6 cars, using appropriate oils and chassis settings for consistent lap-to-lap behaviour.
