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\u003eUpgrade Your New RZR XP Before The First Failure\u003c\/h2\u003e\n\u003cp\u003eOn a current machine the usual question is whether to do this now or wait. If bigger tires or a lift are already on the list, the joints are the part that notices first, and the set of four covers a complete front end. Confirm you are on the 2024-or-newer XP rather than an XP 1000, then decide between one, two or all four. The Keller rebuild kit for Polaris services these later rather than replacing them.\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\":\"Is this for the new RZR XP or the older XP 1000?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"This listing is the current RZR XP, 2024 and newer.
