Order the XP 1000 listing for that machine — fitting the wrong one is the most common mistake on this platform.\u003c\/p\u003e\n\u003ch3\u003eDo Keller ball joints require A-arm modification?\u003c\/h3\u003e\n\u003cp\u003eStandard Keller joints do not — they thread into the factory arm as supplied.

Replacing a single failure is fine, but on a high-hour machine most riders do all four at once so the front end is consistent and they are not back under it in a month.\u003c\/p\u003e\n\u003ch3\u003eCan these be rebuilt instead of replaced?\u003c\/h3\u003e\n\u003cp\u003eYes.

The design has barely changed because it does not need to: thread the housing in like a nut and bolt, use a chromoly stud, and make the whole assembly serviceable so a worn joint gets rebuilt rather than binned.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eComplete Your RZR S 1000 Front End Rebuild\u003c\/h2\u003e\n\u003cp\u003eBefore ordering, confirm you are on the S 1000 rather than an XP car, then decide whether you are replacing a single failure or refreshing all four corners — the set of four covers a complete front end. If the boots are torn but the joints are sound, the Keller boot replacement kit is the cheaper fix. If the joints are worn but the housings are good, the Keller rebuild kit for Polaris services them. Tie rods and A-arm bushings are worth inspecting while everything is apart.\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\":\"Why do RZR S 1000 ball joints pull out of the A-arm?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The factory joint is retained by a snap ring seated in a groove.
