The Boxed Strength You Need
Whether you're cruising through rocky desert terrain or bogging through peanut butter mud, your A-arms take a beating. That’s why you need to get rid of stock and upgrade to SuperATV’s Polaris RZR 4 900 High-Clearance Boxed A-Arms.
Ground Clearance for Tougher Trails
When you need to get over a log or a rock, the 1.5” of extra ground clearance these boxed controls arms give you make a huge difference. They make rough trails feel smooth and keep you rolling forward without getting hung up. What makes boxed arms the best you can get? They’re made with 1/8” steel plating and use internal gussets to boost their strength even further. The UV-resistant powder coating protects from corrosion and they come with preinstalled UHMW bushings. With end-to-end durability, you can take them on hard rides for years. 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. Want to spend more time on the trails and less time in the garage? Purchase a set of SuperATV ball joints with your A-arms and we’ll install them for you for free! We save you money and time so you can get back to doing what you love.
