The AM14U4 and AM14U5 support a multitude of wheel upgrade options. The six-wheel-drive drop center with six-inch HiGrip wheels that comes standard is a phenomenal start point. If you want something different though, this page can help visualize what you might want to change to!

Four-wheel drives are used solely with omnidirectional Mecanum drives. We recommend not choosing a four-wheel drive with traction-style wheels. Mecanum drive is available in 4"and 6" flavors.
All mecanum upgrade kits are used in conjunction with a frame only am-14U4 or am-14U5. You do not need an entire KoP chassis to use this upgrade kit.
For six-wheel drive, the center axle is lowered 0.140 inches on long frames and 0.07 inches on wide frames. This center drop allows for a better turning radius and helps to prevent "scrub" as you turn.
The six-wheel drop center is a tried and true drivetrain proven to be capable of Einstein level play.
The eight-wheel drive expands on the success of the six-wheel drop center drive. The eight-wheel drive has an even smaller wheelbase and the inner four wheels are dropped 0.129 inches compared the outer four wheels.
This creates a more stable chassis with less rocking than a six-wheel drive. This also allows for better obstruction traversing with less chance for a high-center scenario.
Deciding which drive to go with sometimes can be inspired by a specific wheel type, rather than by how many wheels you wish to use. Check out the various benefits for each wheel type below.
Want to traverse in any direction at any time? Mecanum. Want to avoid wasting time to turn when you could just strafe to the side? Mecanum.
Available in four and six inch diameter options, the best omnidirectional drive wheels are here.
All three mecanum upgrade kits are used in conjunction with a frame only am-14U4 or am-14U5. You do not need an entire KoP chassis to use this upgrade kit.
When dropping from heights is a concern and you want to avoid plastic cored wheels, Performance Wheels are the superior choice. These wheels are made from strong extruded aluminum and can handle impressive shock loads.
Performance wheel upgrade kits are to be used with a full am-14U5 chassis. A frame only will not provide enough components to support these upgrade kits.
More traction means more better! These performance wheels feature everything we love about our performance wheels but pack an extra punch. These wheels are wider, allowing additional surface area with the ground for exceptional grip to the ground. When you need a heavy-duty wheel with lots of replaceable grips, XL performance is hard to beat.
Pneumatic wheels give a slight suspension to your robot, allowing varying levels of movement from acceleration. These wheels function just like your car wheels and have a changeable tire with an inflatable inner tube. These wheels feature a plastic core and are available in eight and six inch diameters.
All the benefits of pneumatic wheels, but with an all metal core. If you need to allow for some compliance in how your robot handles Pneumatic wheels are the way to go. If you anticipate heave drops or hard hitting surfaces in your way, these metal cored wheels will give you the best of all worlds.
Pneumatic HD upgrade kits are designed to work with am am-14U5 Frame Only, however, you will also need two gearboxes of your choosing.
When absolutely zero scrub is desired "Corner Omnis" has proven hard to top. With a DuraOmni upgrade package, the four corner wheels in a drop-center six-wheel-drive are replaced with DuraOmnis. This means when you attempt clockwise and counter-clockwise rotations, there is very little resistance as the rollers of the corner omni wheels spin and allow a rapid swivel of your robot.
This kit is used in conjunction with a full am-14U4 or am-14U5 bundle.
HiGrip wheels are TPU treaded, plastic cored, wheels. The tread pattern of these wheels is aggressive and will bite into carpeted surfaces exceptionally well. These wheels are so reliable they're featured in the Kit of Parts chassis. These can be configured in the stock six-wheel, up to eight-wheel, or with varying durometers. The softer the wheel the more grip and higher wear.
If you want lower durometer HiGrip wheels and have a full am-14U5 already, simple pick up six or more new six inch diameter HiGrip Wheels.
