I have the 1.5" forward A-arms. They A-arms themselves are nice and they hold up well, but the bushings they send with them don't hold up worth a darn. I had 2 rides on a set of bushings and they pinched/deformed so bad that I couldn't drive the Viking without replacing them. I could literally grab the front wheels and shake the wheels about 1/8 - 3/16" inch in and out at the top of the wheel.
In my opinion, SuperATV customer service sucks. I told them about the problem and all they had to say was "you'll have to pay $80 for new bushings as they are a wear and tear item". Let me be clear. That's $80 for HALF a set of bushings. All my bushings were deformed and needed to be replaced, not just half. And these things are literally just plastic. You need 2 sets to switch them out so your looking at $160.
Look closely on the 1.5" forward A-Arm notes on their website (pic below taken moments ago). It explicitly mentions ball Joints, and Tie rods, but not bushings. When I talked to Kristen Smith about the cheap bushings they sent me, all they could say is "yeah, but the website doesn't say bushings 'are' covered by the warranty." Finally, they agreed to send me a set of bushings to replace the ones I was only able to get 2 rides out of and when I opened the package, there was only enough to do one side of the Viking! I was pissed. After all the discussions we had and how all the bushings failed, and how they said I had to take the old bushings off and send photos before they would send me new bushings, they only sent me enough to do one side. So my Viking was up on jack stands for an additional week taking up space in the shop. Some people are just plane dumb.
Are the A-arms good quality? Yes. Can I recommend paying the extra money for something that is going to cost you $160 for 16 pieces of plastic after a few rides? No, I cannot recommend them. Maybe if SuperATV wasn't into charging such outlandish prices for a replacement set of bushings I could recommend them. Your going to be replacing a lot more than just the A-arms on your Viking if you don't stay on top of their bushings.
Also, they say you can clear a 30" tire with no rubbing but I have 28" tires and my tires still rub. Others claim they get now rub, but they have the 2in lift kits installed, which really just limit the top 2" of suspension travel in your suspension. There are lots of discussions on here about these lift kits. All I can say is do you homework before you buy.
