Polaris General 1000 ball joints fail at the snap ring, not the joint itself. The General is a crossover — it works like a Ranger and gets ridden like a RZR — and that thin retaining clip is the part that notices. It deforms or shears under hard landings and the extra leverage of bigger tires, and once it goes the joint has nothing holding it in the A-arm. Keller ball joints remove it entirely — the two-piece housing threads into the arm like a nut and bolt. Hardened 4340 chromoly, greaseable, adjustable and rebuildable.
Todd Keller's original threaded design, covering the General from 2016 onward and the four-seat General 4 from 2017. On this machine the same joint serves both positions, so you simply choose how many you need.

Built To Solve: General 1000 Ball Joint Pull-Out and Snap Ring Failure
- Snap ring shearing and letting the joint separate from the A-arm
- Clunking or knocking from the front end over rough ground and whoops
- Play in the wheel when rocked top-to-bottom on a jack
- Repeat OEM joint failures on a machine that both works and plays
- Torn boots admitting water, mud and grit so the joint wears from the inside
- Replacing the same joint often enough that it has become routine maintenance
Best For: General 1000 Builds That Work Hard And Ride Hard
- General and General 4 owners running larger tires or added lift
- Riders who tow or haul during the week and hit trail on the weekend
- Owners who have already replaced a factory joint more than once
- General 4 owners carrying more weight through the front end
- Anyone rebuilding a front end who wants to do it once
Check your model carefully — the General 1000 and the General XP 1000 use different Keller joints and have separate listings.

FAQ
Why do General 1000 ball joints pull out of the A-arm?
The factory joint is retained by a snap ring seated in a groove. Hard 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.
Will these fit my General XP 1000?
No. The General 1000 and the General XP 1000 use different Keller joints. Order the General XP 1000 listing for that machine — confirming which one you have before ordering saves a return.
Do these fit the four-seat General 4?
Yes, from 2017 onward. The two-seat General is covered from 2016, so the four-seat machine starts a year later.
Do I need different joints for the upper and lower positions?
No. On the General 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.
Do Keller ball joints require A-arm modification?
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.
Can these be rebuilt instead of replaced?
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.
Why Keller
Todd Keller designed the two-piece threaded ball joint to fix the one part of a stock front end that keeps failing, and SuperATV now builds and backs the line. 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.
Complete Your General 1000 Front End Rebuild
Before ordering, confirm you are on the General rather than the General XP, 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.
