Three different designs for the Gen 4/5 front bumpers are available, depending on which factory skid plate option you are running on your sled:

The one piece design is for use with the wider Full Body poly skid plate. There are two different 2 piece designs – one being for use with the skinny Deep Snow poly skid plate and one for use with no factory skid plate.

The 2 piece design, is as states, two pieces, which incorporates a lower aluminum skid plate portion which bolts to bottom casting in 6 locations. The main front then bolts to this lower aluminum skid plate making for the more solid front bumper of the two designs, as the full body skid plate front bumper design we offer mounts to the factory poly skid plate on the lower portion of our bumper.

The Gen 4 and 5 rear bumpers are one solid piece, fully tig welded handle design. The tunnels on the Gen 4 are the same as the Gen 5’s, so no need to worry if it will fit or not. The only info we need to know accurately is the tunnel length, not the track length.

For the new Gen 5’s, the experts and the Free Ride have the next size shorter tunnels. For example. 165 summit X with expert package has a 154 tunnel. This applies to some of the Gen 4’s, but not all.. An easy way to tell is looking at the machine from the side, if the tunnel is as long or slightly longer than the track its a regular model and the track length is the tunnel length info we need. If the track is noticeably longer than the tunnel your have the next size shorter tunnel than the track length.
