After enough years, the internals of a Keller ball joint wear out — but the threaded housing in your A-arm usually does not. This kit replaces the parts that actually go: a new cup, a new boot and a 4340 steel heat-treated pin, identical to the ones your joint was built with. Your rebuilt joint goes back together good as new, at roughly half the cost of replacing it.
Seven versions cover the Honda Keller range across Pioneer and Talon 1000 machines, in upper, lower and Mega form. Match the kit to your joint's part number.
Key Features
- Includes a new cup, new boot and 4340 steel heat-treated pin
- The same high-quality parts that came with your original Keller ball joint
- Roughly half the price of buying a new joint
- Seven kits covering Pioneer and Talon 1000 Keller joints, standard and Mega
- Keeps the threaded housing in the A-arm
- Made in USA
Built To Solve: Worn Keller Ball Joints on Honda Pioneer and Talon Machines
- Play developing in a joint after years of trail and work miles
- A gritty or notchy feel when the stud is articulated by hand
- A joint contaminated after a torn boot let water and dirt in
- Front-end noise returning on a machine whose joints were fine last season
- Facing the price of new joints when only the internals are worn
- Wanting a service pack on the shelf before a long trip or a work season
Best For: Pioneer and Talon Owners Servicing Keller Joints They Already Run
- Pioneer owners running Keller uppers or lowers
- Talon 1000 owners running Keller joints in either position
- Riders running the Pioneer 1000 Mega upper joint
- Work and trail machines with sound housings and worn internals
- Owners who chose Keller because the joints come apart for service
If a boot has split but the joint is still tight, the Keller boot replacement kit reseals it for less. If the housing itself is damaged, you need a new joint.

FAQ
What is in the rebuild kit?
A new cup, a new boot and a 4340 steel heat-treated pin — the same parts your Keller joint was built with. Keller's own description is that the rebuilt joint will be good as new.
How do I know which of the seven kits I need?
By the part number stamped on the joint. Position matters here — uppers and lowers take different kits — and the Pioneer 1000 lower changed part number in 2022, so the model year matters too.
Which machines does the Pioneer upper kit cover?
Keller uses the same upper joint across the Pioneer 500, 520, 700 and 1000. Because one part serves several machines, the reliable way to order the right kit is the joint's part number rather than your model.
Do I have to take the joint out of the A-arm?
The threaded housing stays in the arm; you are replacing what sits inside it. Keller does not publish a step-by-step rebuild procedure on this product, so allow time and work carefully if it is your first.
Is rebuilding worth it against a new joint?
Keller prices the kit at roughly half a new joint and you keep the housing, which is the precisely threaded and expensive part. Across a front end that adds up.
My boot tore but the joint feels tight. Do I need this?
Probably not. With no play and smooth stud movement, the Keller boot replacement kit is the correct and cheaper repair. Use a rebuild kit when the internals have genuinely worn.
Why Keller
The 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 real — the same cup, boot and pin the joint was assembled with, sold on their own.
Service Your Pioneer or Talon Keller Joints Before They Let Go
Before ordering, read the part number off the joint and match it to the list above — uppers, lowers, Mega and the two Pioneer 1000 lower generations all take their own kit. 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. On a work machine, keeping a kit on the shelf turns a worn joint into an evening in the shop rather than downtime waiting on parts.
