Product Description
A Smarter Kind of Ball Joint
Keller ball joints were designed to address the shortcomings of the standard ball joint design. Instead of using a snap ring, Keller’s reimagined ball joint uses a threaded housing to make it virtually impossible to pull out. When you combine that with a hardened chromoly steel construction throughout, it’s easy to see why you need SuperATV’s Honda Pioneer 520 Keller Ball Joints on your machine ASAP—they have the strength to go the extra mile.
Long-Lasting Durability
Your Pioneer 520 puts in plenty of hard work, so it’s only fitting to have ball joints that can work hard too. With a two-piece ball joint, one side gets pressed in and the other threads onto the back like a nut and bolt, giving you the most secure installation possible. And it’s made even more robust thanks to the all-chromoly construction. Plus, it’s greaseable and adjustable so you can have optimal stud stiffness for years of riding.
Time to Go Big
With Keller Ball Joints on your Pioneer 520, you can make the biggest, meanest rig out there. Put huge tires on and lift it sky high—with these ball joints installed, you can push it ride after ride without breaking a ball joint.
