Fixed Axle
A fixed axle is a solid axle that is fixed or welded to the frame. So, the wheels have the bearings in them and that is what lets the wheels spin at high speeds. Usually a fixed axle means the go cart is one wheel drive. With a fixed axle, the sprocket is fixed directly to one wheel that is on the fixed axle by bearings allowing it to spin. This is the worst possible choice for off road go carts. Although it isn’t impossible to do some light off roading with a one wheel drive but we do not advise it.

Pose Rear Axle
A pose rear axle is a solid axle where the axle bearings are attached to the frame and the wheels are fixed to the axle. So, when the axle turns so do the wheels. This set up has no slip so if turns are taken too hard and to fast the go cart will hop or jump because both tires are moving at the same speed. This is one of the best options for off road because is cost effective, performs excellent and most off roading does not require high speed turns.

Rear Differential
A rear differential is not meant for off road. The reason a rear differential was made was to allow high speed turns without allowing the cart to hop. So, how it works is when one wheel loses traction it stops moving allowing the other to spin. When you’re stuck in the mud or going through dirt you to not want one wheel drive and this is what ultimately happens with a rear differential. If you are planning to use the go cart some light off road driving and then use it on road as well, then a rear differential may be the way to go.

CV Joined Axle “Front”
A CV joined axle is usually found in front wheel drive cars the CV joint allows the axle to bend while spinning allowing the wheels to be turned while driving. This is the only type of non-fixed axle available for the front. So if 4 wheel drive is available or desired, you will need a CV joined axle for the front.
