    X2 Portal Build

    The accessories keep piling on, but I my have reached the summit! I found very little info. regarding portals for an X2, so I will share what I have learned. I was disappointed in the lack of ground clearance and lift options for the X2, so I went all out and ended up with a small Jeep!

    The machine is a 2019 X2 that was sitting on 30" Blackwater tires and then it transformed by installing 4" GDP portals with 30% gear reduction on 33" tires. The install was pretty straight forward. I have no other lift at the moment. The front shock preload is currently set 1/4" past the max. suggested in the manual, while the other adjustments are in the middle of the range. Rear shock preload is set at max. soft.

    I thought I would try 15" wheels to gain more clearance between the portals, brake caliper, and the wheels. Apparently, rocks can get caught between the wheel and caliper and break things, not common, but can happen. You can run 14" wheels, but nothing smaller. I went witih System 3 XT300 tires in 33x10-15 on 15" System 3 beadlock wheels with a 5+2 offset. Folks say you can run 6+1 offset to keep the stance narrower and less fatigue on steering, but SuperAtv said you could not, so I went with the more commonly used 5+2. I also added 1" Superatv wheel spacers in the rear to help even the width front/rear. It's about 70" wide now. I also went with the more common and larger Polaris bolt pattern on the wheels. You can choose any bolt pattern with the portal hubs - you install the wheel studs in whatever holes that you choose.

    The tires rubbed on the front inner fender badly with that setup, so I installed the new 1.5" Superatv forward arched A-arms in the front suspension. That moves the front hubs/wheels forward 1.5" to deal with rubbing. It worked. We rode about 50 miles yesterday and I don't think it rubbed all day. The tires will rub with this setup, but only if you stuff the tires pretty hard while turning. Of course I wish that they did not rub at all, but I think it will be fine. All kinds of clearance in the rear fender openings with this setup. It has about 17.5" of ground clearance with 10 psi in the tires, which gives them a slight bulge at the bottom.

    It looks and drives a little more like a lifted pickup. It's geared low! I have also installed the Hunterwork machined sheave and 18g weights. The machine hits the rev limiter at 52 mph just like before, and the actual speed was clocked at about 45-46 mph when the speedo reads 52 mph. If I did the math correctly, that is about 13% lower geared than the factory setup with 26" tires. In low gear it turns the tires very slow almost like a "crawler" rig. I have only had it out for 1 good ride and that was in snow and ice, not challenging conditions. I suspect that it will crawl through mud holes and rough terrain really well, but that will have to wait for a few months here in AK.

    Other mods include: Warn 4500, Inferno heater witih Ice-crusher T-stat, fender flares made from trucker mud flaps, etc. I am going to consider making a new bed for the machine for more storage for hunting/camping.

    Awesome pics! How did the stability change after the build. Less tippy?

    Hmm, not much time riding yet. It certanily sits higher, but it's also wider, and with the extra weight of the portals and big tires/wheels down low, maybe the center of gravity won't be any worse - dunno? I am not as inclined to spin donuts in the snow/ice with the current setup as compared to stock! Time will tell. Obviously this isn't a "racey", haul ass setup, but rather a lifted crawler to get through deep mud, over obstacles, etc., kind of rig, which is what I was looking for. I have a good feeling it will do well crawling around AK trails - at least it better!

    AK, do you think 32's would have fit better (no rub) without the SA arms? Or would they still have made contact? And how do those tires work plowing?? What's the top rear of the cab measure now?

    Pretty cool build btw!

    Looks real good, thanks for the info.
    SuperATV recommended shock preload settings?
    How's the steering feel? I hear a few say that it made the steering very heavy, but they were RZR's.

    Adapt your machine to how you intend to use it.
    Every mod you do to a machine will have gains somewhere and losses in other areas.
    Decide what you want and what you can live with or without.

    Another guy on this Forum built an X2 with 4" portals, installed 32x10-14 XT300 tires, 5+2 offset, no other lift, and he said that he rubs, but not enough to worry about. I kind of wanted to try 15" wheels so I went with 33's. Mine rubbed really bad w/o the offset A-arms and so I am surprised that 32's work as well as he stated. I have only plowed once with those tires and it wasn't much of a test for them. There are probably better options for snow. I wanted the wide/square profile for muskeg type mud - more surface area. The XT300 tires are relatively light for an 8 ply tire, both of which were factors for me choosing them. I'll try and remeber to get a cab height the next time it's in the garage. We went for another ride today and I am liking it so far.

    No recommendations on shock settings. I was just playing with settings to see what works best and to help deal with tires rubbing. I've ridden about 90 miles so far and have only rubbed a few times. I'll probably reduce the front pre-load as much as I can until it starts rubbing again. I've only driven on snow and ice so far and steering seems fine. The square profile tires are supposed to steer much heavier then the round profile tires. The other forum member has nearly the same setup with 32"s and he had nothing bad to say about it. The Slickrock guys have a Youtube video about square vs round profile tires - they praise the round profile because they are easier on steering components, BUT they ride on slickrock/bedrock. I think and hope that the square profile will work well in AK trail condtions.

    Cool and thanks.
    Yeah I tend to lean towards a round profile as for higher speed driving & lighter steering, but in a crawler I'd think square would be better.
    Thanks again for the pics
