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

Rear Topdeck Replacement for Serpent 4X FWD

This Arrowmax AM-920034 rear topdeck is supplied as a replacement for the rear topdeck position on Serpent 4X FWD models. It acts as a chassis brace, altering torsional stiffness and the rear suspension response, which produces a controllable change to handling when introduced into a setup routine.

Installation is straightforward for those used to 1/10 on-road assembly and calls for basic hex drivers. Remove the existing rear topdeck, clean mating surfaces to remove any paint or burrs, fit the Arrowmax topdeck into the rear position and tighten fastenings evenly without over-torquing to protect the mounting points. Re-check wheel alignment and suspension travel after fitting.

For tuning the 2.0mm topdeck helps refine chassis flex characteristics and is typically paired with anti-roll bar, damper and shock mount adjustments to balance rear grip and turn-in behaviour. Use it as part of an overall setup plan rather than expecting it to solve every handling issue.
