Order one kit per joint you intend to rebuild. If a boot has split but the joint is still tight, the Keller boot replacement kit is the right part instead.

Order one kit per joint you plan to rebuild. If the boot is the only problem, the Keller boot replacement kit is the right part instead.

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 900 Front End Rebuild\u003c\/h2\u003e\n\u003cp\u003eBefore ordering, confirm your exact 900 variant and year, 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 900 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. Landings and the extra leverage of bigger tires can deform or shear that ring, and once it goes the joint has nothing holding it. Keller joints thread into the A-arm instead, so there is no clip to fail.\"}},{\"@type\":\"Question\",\"name\":\"Do these fit the RZR S 900 and the four-seat cars?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes. The RZR 900 and RZR S 900 are covered 2015-2020, the RZR 4 900 2015-2018, the RZR S4 900 in 2018 and the RZR XC 900 2015-2017. Match your own year to the list before ordering.\"}},{\"@type\":\"Question\",\"name\":\"Do I need different joints for the upper and lower positions?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"No. On the 900 the same Keller joint serves both positions, which is why this product is sold by quantity rather than by upper and lower. Choose one, two, or a set of four for a complete front end.\"}},{\"@type\":\"Question\",\"name\":\"How many do I need for a full front end?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Four - two per side. The four-joint option covers a complete front end, which is what most owners order when they are rebuilding rather than chasing a single failure.\"}},{\"@type\":\"Question\",\"name\":\"Do Keller ball joints require A-arm modification?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Standard Keller joints do not - they thread into the factory arm as supplied. The Mega version uses an oversized housing and does require machined A-arms, which is the main reason to pick one over the other.\"}},{\"@type\":\"Question\",\"name\":\"Can these be rebuilt instead of replaced?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes. They grease and adjust, and the Keller ball joint rebuild kit for Polaris services them with a new cup, boot and pin when the internals eventually wear.\"}}]},{\"@type\":\"VideoObject\",\"name\":\"How To Install Keller Ball Joints With Todd Keller\",\"description\":\"Official SuperATV walkthrough showing how Keller two-piece threaded ball joints install into the A-arm without a snap ring.\",\"thumbnailUrl\":\"https:\/\/i.ytimg.com\/vi\/Mbt4iX4DWRA\/hqdefault.jpg\",\"uploadDate\":\"2022-08-03\",\"embedUrl\":\"https:\/\/www.youtube.com\/embed\/Mbt4iX4DWRA\",\"contentUrl\":\"https:\/\/www.youtube.com\/watch?v=Mbt4iX4DWRA\"}]}\u003c\/script\u003e","brand":"Keller","offers":[{"title":"1 joint","offer_id":67590745915428,"sku":"BJK-P-RG#AO","price":153.95,"currency_code":"USD","in_stock":true},{"title":"2 joints","offer_id":67590745948196,"sku":"BJK-P-RG-K-2#AO","price":307.9,"currency_code":"USD","in_stock":true},{"title":"Full front end — 4 joints","offer_id":67590745980964,"sku":"BJK-P-RG-K-4#AO","price":615.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0694\/6488\/3236\/files\/bjk-p-tspr-k-4_2_2_1_1_1_1_0331be05-a93a-4b2a-b61e-2ef70f770a53.jpg?v=1790927821"}],"url":"https:\/\/dunes2dezertsxs.com\/collections\/keller-ball-joints.oembed?page=2","provider":"Dunes 2 Dezert SXS","version":"1.0","type":"link"}
