Polaris RZR 4 900 High-Clearance Front A-Arms

When you're tackling rough terrain, your front A-arms take a beating. Stock arms sit low and can hang up on rocks, logs, and trail obstacles—that's where these high-clearance units come in. They lift your suspension 2" higher, so you clear more without needing a full lift kit. The tubing is also noticeably thicker than what comes from the factory, so it shrugs off the kind of impacts that would bend or crack weaker arms.

Ground Clearance That Matters

The 2" of extra ground clearance comes from a precision bend design that doesn't compromise suspension geometry. You'll roll over bigger stuff more easily, and that extra height translates to a smoother ride when you're picking your way through nasty terrain. All that clearance without needing to add weight or complexity to your machine.

Built Heavy, Built Right

These arms use 1.25" diameter tubing—25% thicker than stock. That means real durability when trail debris or rocks find your undercarriage. They ship with self-lubricating UHMW bushings already installed, so you're ready to bolt them on. SuperATV backs them with a lifetime warranty because they know these things can take a hit.

Tune Your Camber If You Need To

Out of the box, they're set to stock specs. But if you add weight, gear, or decide to run a lift down the road, the adjustable pivot blocks let you dial in your camber to keep tire wear even and handling dialed. No guessing, no trial and error.

Ball Joint Options

You'll need to pick a ball joint setup—or reuse your stock ones if you're keeping costs down. Three choices are available:

Super Duty 300M: Made from 300M grade steel, these are the strongest option. They're 2.25× tougher than stock, come with grease zerks for easy maintenance, and use an adjustable steel-on-steel design that stays reliable mile after mile.

Heavy Duty: Built from hardened 4340 VAR steel with zinc plating, these handle double the stress of OEM joints. Also feature accessible grease zerks and an adjustable design for flexibility in the field.

Standard Duty: Hardened chromoly steel construction with zinc plating gives you OEM-level strength at a lower price point. Solid, proven design that matches or beats stock durability.

If you want SuperATV to install ball joints for you when you order, they'll do it free—saves you time and money getting back on the trail faster.
