These are for the ProCross/ProClimb chassis with 1/2" or 1" (please specify) rail slots that originally had 8" wheels.  Runs 4 wheels and eliminates the plastic hub.  Measure your sled for fitment. Sleds with coupled rear suspensions should check for clearance between the wheels and the cross bar for the rear suspension arm stop.  The kit comes with the billet offset axle that allows the use of these larger than original wheels and 2 billet powder coated wheels (in your choice of colors and 2 styles) for the outers and 2 black plastic wheels for the inners.
 
Add a custom look while addiing performance by reducing rolling resistance.  
 
The rubber on our billet wheels isn't glued on like some of the other guys, that simply just doesn't last. Our rubber fits into a machined groove in the wheels kind of like a car tire.  The rubber allows your wheels to be run with a studded track, provides protection in low-snow conditions and  will not get ice build up, which can happen if you don't have rubber on your wheels. Our supplier has been making billet wheels with rubber since 2008 and has had great results, having many customers that have over 10,000 km on the wheels with no issues with the rubber failing.
 
The billet wheels are offered in 4 powder coated colors and kits are built to order so please allow 3-4 weeks delivery time.
