Chassis Kits (3-sizes)

In stock

Standard VEX chassis kits include (2) bumpers and (4) rails apiece. The flexibility and variety of design options makes these a great starting point for any mobile robot project.


Note: Chassis sizes are listed by number of VEX holes, (i.e. a 15 x 25 chassis is 15-holes wide x 25-holes long).
  • Rail mounting locations allow for variable chassis width
  • Space between rails is ideal for a protected chain run or gear reduction
  • Wheels may be mounted outboard or between the rails for extra support
  • "Super" chassis is taller with more vertical mounting locations
  • Rails sold separately for additional versatility
