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

Rear Topdeck Upgrade for Serpent 4X

The Arrowmax AM-920034 rear topdeck is an RC replacement part for the rear topdeck location on Serpent 4X FWD vehicles. Acting as a brace, it changes chassis torsional stiffness and influences how the rear suspension reacts to steering and throttle inputs, delivering a measurable handling shift when used as part of setup adjustments.

Installation is simple for experienced 1/10 on-road builders and only needs basic hex tools. Remove the stock rear topdeck, ensure mating surfaces are clean and free of paint or burrs, mount the Arrowmax topdeck at the rear, and tighten screws until secure but not over-torqued to avoid stressing mount points. After fitment double-check wheel alignment and full suspension travel.

In tuning this 2.0mm rear plate is commonly used to adjust chassis flex, usually in combination with anti-roll bar, shock and shock mount changes to balance rear grip and turn-in behaviour. Treat it as a component of a broader setup strategy.
