Durable and Thick Wheels 76mm x 30mm for Shift [V1+]/Crazy Cart [V7+] and Crazy Cart XL [V3+] - Set of 2 Premium Replacement Wheels，parts W25143401048-Replace reliable parts for Krazy Kart.

We go through a lot of these wheels with a few crazy carts in out possession. The durability and dimensions are about the same as those we have sources directly from the manufacturer. These wheels are always a significant wear item when it comes to crazy carts and especially if your riding on rough concrete or asphalt. The installation was simple and the wheels come with bearings and spacers just like all of the rest. A great price for something we have replaced about 10 times in a few years of cart ownership.

I am liking these PU wheels as they met the challenge. The wheels are thicker and hold up to weight and downward forces. I used these PU wheels to replace my plow skid roller skate wheels that help with inconsistent surfaces and getting my tractor plow JD 42” to float over the street and driveway. The positioning of the wheels also helps preserve the rubber blade. The photo shows the mounting. These PU wheels by virtue of size, high quality sealed bearings, bearing spacers and the ability to handle loads similar to that of a crazy cart with an adult on board. After three uses the wheels are not indicating much wear. Install was easy!

I would give 5 stars BUT.... there is a collar or sleeve between the two bearing races. The photo shows how the it is misaligned with the races. It doesn't matter much but it is annoying when you install. In the two wheels one collar was free to move when inserting a bolt you might have some problems, the other the collar was misaligned but not free to move. In that case I had to use a small screw driver to line it up. The collar doesn't affect the wheel's usage just makes it harder to install. The collar is designed as a spacer to make sure the bearings are not pushed into the middle of the wheel. The design could be better. However, the design is still 100% functional, at least in my case.

We got these wheels to use on a kitchen cart that we are building. They work just fine, although you do need to get everything lined up in order to install them.

This is the best quality replacement wheel I have ever used
