In stock
Compatible with products and accessories.
VRC, VEX U, VAIC, FTC legal.

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.

  • 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
  • Rails sold separately for additional versatility

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).
