Keller does not publish a step-by-step rebuild procedure on this product, so if you have not done one before, allow time and work carefully rather than assuming it matches another brand's process.\u003c\/p\u003e\n\u003ch3\u003eIs rebuilding actually worth it versus buying a new joint?\u003c\/h3\u003e\n\u003cp\u003eKeller puts the kit at roughly half the price of a new ball joint, and the housing — the expensive, precisely threaded part — is reused. On a machine with several worn joints the saving is significant.\u003c\/p\u003e\n\u003ch3\u003eMy boot tore but the joint feels fine. Do I need this?\u003c\/h3\u003e\n\u003cp\u003eProbably not. If there is no play and the stud still moves smoothly, the Keller boot replacement kit reseals it for less. Use this rebuild kit when the internals have actually worn.\u003c\/p\u003e\n\u003ch3\u003eDoes this fit Mega Keller joints too?\u003c\/h3\u003e\n\u003cp\u003eYes. Three of the ten kits service Mega joints — the RZR XP 1000 Mega, the RZR Turbo S Mega and the Ranger Mega. That matters if your A-arms were machined for Mega housings, because rebuilding avoids disturbing that work.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eWhy Keller\u003c\/h2\u003e\n\u003cp\u003eThe rebuildable design is the whole argument for Keller. A joint that threads into the A-arm and comes apart for service is one you fix rather than replace, and this kit is what makes that promise real — the same cup, boot and pin the joint was assembled with, sold on their own.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003eService Your Polaris Keller Joints Before They Let Go\u003c\/h2\u003e\n\u003cp\u003eBefore ordering, read the part number off the joint and match it against the list above — the HCR-arm and mud pin versions have their own kits and are easy to get wrong. 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. Riders who ride hard often keep a rebuild kit in the trailer, since a joint that starts to feel gritty on day one of a trip is repairable rather than trip-ending.\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\":\"What is in the rebuild kit?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"A new cup, a new boot, and a 4340 steel heat-treated pin - the same three parts your Keller joint was built with.
