The Serpent SER401797 Topdeck Post adds reinforcement to the Project 4X PRO EP chassis, helping control upper deck movement. At 15.5mm this post is aimed at keeping the chassis rigid during demanding driving and quick direction changes.
Specifically manufactured for the Serpent Project 4X PRO EP (SER400032), the topdeck post provides a reliable fit that reduces flex and helps maintain predictable handling through a range of track conditions.
Tighten the post to a secure setting without overstressing the threads, and inspect the mounting after initial runs. Regular checks after impacts will help avoid slack or wear-related handling issues.
