The Serpent Project 4X PRO 1/10th scale touring car is the evolution of the 4X EVO. A part of the Project 4x series, this kit shares all features of the 4x Evo, including the same easy to install shock system and fixed-length pull-rods. The vertical top-deck has been replaced by a horizontal topdeck, giving a more aggressive steering on high grip surfaces. The rear suspension is heavily modified with much longer arms and updated geometry to create better steering and a wider set up on medium to high grip asphalt. For maximum rear stability and steering precision there is a fixed-toe rear wheel carrier included with the kit. The Project 4X Pro provides more flexibility and improved performance on any surface!


  • Updated rear suspension. 
  • Race proofed with multiple ETS A final results and Podium at the IFMAR World Championship.
  • Fixed-toe rear for stock racing with maximum rear stability and precision, both fixed and adjustable link options included in the kit.
  • Horizontal topdeck for more steering on high grip surfaces.
  • Keyed topdeck for reduced risk of chassis tweak
  • 2MM carbon fiber chassis with additional holes for more flex options
  • Separate roll and heave motion in the car to make set-up easier and more precise

  • Durable and smooth gear differential
  • One screw ride-height adjustment from chassis side
  • Lightweight front aluminum spool with hardened steel outdrives, bladeless.
