I've always been a fan of these wheels since I go my first Rampage TT back in 2008 so thought it'd look cool if a slapped a set on my Chimera EP Pro.
As you can see from the pictures, these wheels do fit on the Chimera but the wheel nuts will only thread about half way on so you'll want to use some threadloc to make sure they do not fall off
For the XT and XB, you have to swap out your front and rear axles as well as the hubs to the Chimera units, then you'll be able to install the wheels. Here's a quick parts list:
1 x 07427 Wheel Mount Set (4)
1 x 07409 Rear Axles (2)
1 x 07428 Universal Drive Joint (2)
