A-Arms That Are Built for Battle If you™re still running stock arms, you don™t know what you™re missing out on. Stock arms bang on every low-lying obstacle and the weak construction can buckle if you push them too hard. Upgrade to SuperATV™s Polaris RZR Trail S 900 2" Forward Offset Boxed A-Arms to get smoother, more reliable rides. The 2 forward offset boosts stability and gives you room to fit up to 30 tires. Combine that with the high-clearance bends and you can cruise right over obstacles and take massive hits without breaking. Room to Fit up to 30 Tires These boxed control arms are designed to get over stuff thanks to the 2 forward offset and high-clearance bend design. You get room for up 30 tires without a lift and 1.5 of extra ground clearance. That makes it harder to get hung up on branches and rocks and makes the whole ride feel smoother. Boxed Strength for Hard Rides Our boxed design maximizes strength from end to end. We make it with TIG-welded 1/8 heavy-duty steel plating and beefy internal gussets. They™re finished with a UV-resistant powder coating to protect from corrosion. Altogether, they™re super strong and have the bold, burly look to match. Plus, they come with UHMW bushings preinstalled for years of smooth riding. And if you somehow manage to break them, we™ve got you covered with a lifetime warranty. Adjustable Pivot Blocks When you add a lift or a bunch of weight to your RZR, you screw up your camber. With messed up camber comes poorer ride quality and shorter tire life. These A-arms come with adjustable pivot blocks set to factory specs so you can always have perfect camber. Let SuperATV Do the Work”Preassembly Available!
