GPM Racing Stainless Steel+ Aluminium Supporting Mount with Front / Rear Upper Arms - 14pcs Set for Traxxas 1/10 MAXX W/Widemaxx 2.0 Monster Truck-89086-4 (TXMW054F/RS)

Precision upper arm support set for TRAXXAS MAXX

This 14pcs supporting mount and upper arm assembly is an aftermarket engineering upgrade for TRAXXAS MAXX platforms. Machined stainless steel and aluminium components replace the front or rear upper arm mounts to improve mounting strength while maintaining low mass, and the design provides an adjustable length mechanism to control suspension geometry and wheel angle for tuning applications.

The adjustable arms allow indexed changes: loosen the mounting screws and use a pin or Allen key to rotate the internal adjustment, altering effective arm length to change toe and camber. This enables repeatable, serviceable setup changes without permanent chassis modification.

Fitment and installation: the kit is intended for direct replacement on compatible MAXX chassis configurations and includes stainless steel pins, screws, and washers. Assembly is performed with standard hand tools and a hex driver for incremental tuning and adjustment verification.
