Serpent Project 4X Rear Topdeck 2.0mm - Arrowmax AM-920034  [AM-920034]

Rear Brace Plate for Serpent 4X FWD

This Arrowmax AM-920034 rear topdeck is a direct replacement for the rear topdeck position on Serpent 4X FWD cars. It works as a chassis brace that alters torsional stiffness and changes how the rear suspension reacts to driver inputs, providing a predictable handling delta when used as part of a setup cycle.

Fitting is straightforward for anyone familiar with 1/10 on-road assembly and requires common tools like hex drivers. Remove the original rear topdeck, clean mating surfaces of burrs or paint, position the Arrowmax unit in the rear location, and tighten fasteners snugly without over-torquing to avoid stressing mounting points. After installation re-check alignment and run suspension through full travel.

In practical tuning the 2.0mm rear topdeck is used to dial chassis flex, typically combined with swaybar, damper and shock mount adjustments to balance rear grip and turn-in behavior. Consider it one tuning element within the whole setup rather than a standalone fix.
