Hefty A-Arms for Aggressive Riding Taking your rig out to play and race with your buddies is only fun if you don™t end up as the joke's punch line. By adding SuperATV™s Polaris RZR XP 1000 Atlas Pro A-Arms to your machine, you can clear stumps, keeping your suspension safe and your ego intact. They're high clearance, beefy, and super strong. They make your already badass RZR even more badass, making it look like a colossal machine. We've perfected our design and made it larger by taking our standard A-arms and increasing them to 1.5" in diameter. That makes them 0.5" larger than your OEM A-arms. Size Up”Atlas Pro Tubing These Atlas Pro A-arms are bigger and better than your stock A-arms. They™re the biggest A-arms we™ve ever designed, measuring 1.5" in diameter and packing insane strength. How big is big? Our design has increased their size to be 0.5" larger than your stock A-arms and a quarter inch larger than our standard A-arms. We didn™t stop there, our heavy-duty 0.138 wall thickness delivers more strength than your stock A-arms any day. Plus, we™ve finished them with UV-resistant powder coating to defend against corrosion and rust for added durability. You haven™t seen anything until you add a set of these bad boys to your rig”they™re beefy and mean business. Optional Adjustable Pivot Blocks Our RZR XP 1000 control arms are available with adjustable pivot blocks, allowing you to change your camber. Adjustable camber is important when you make heavy-duty upgrades (like a lift kit). Tailoring camber to your new setup will improve the life of your tires. We™ve done the hard part and pre-adjusted the pivot blocks to match your machine's stock specifications. You™ll be ready to ride ASAP unless you want to make changes yourself.
