SuperATV builds and backs the line. Nothing here is disposable — the joints grease, adjust and rebuild, so a hard season means a service rather than a new set.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eFinish Your Heavy-Duty RZR Pro XP Front End\u003c\/h2\u003e\n\u003cp\u003eBefore ordering, confirm two things: your model year is 2020 or later, and your A-arms are modified or will be. If they are not, order the standard Keller joint instead. Riders going this route are usually replacing A-arms at the same time, and the Keller rebuild kit for Polaris services these joints when they eventually need attention rather than replacement.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eInstallation Video\u003c\/h2\u003e\n\u003cp\u003eOfficial SuperATV installation walkthrough with Todd Keller: \u003ca href=\"https:\/\/www.youtube.com\/watch?v=Mbt4iX4DWRA\" target=\"_blank\" rel=\"noopener\"\u003eHow To Install Keller Ball Joints\u003c\/a\u003e\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"FAQPage\",\"mainEntity\":[{\"@type\":\"Question\",\"name\":\"Do Mega Keller ball joints really require A-arm modification?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes, and it is not optional - SuperATV states it on the product itself.
