The teeth on your armature plate can bend when you have a rough engagement. If the 4WD on your Polaris starts becoming unreliable, your armature plate is the first thing you should check. Our armature plates fit tons of front diffs, including our SwifTrac front differential for Can-Am machines. Our armature plates are made from hardened steel to make them as tough as possible so you can avoid damaging them like you did with stock. Plus, they cost a fraction of OEM—we’ll get your front differential back in perfect condition without blowing your budget.
