What’s the Difference between JBA Max 90 Ball Joint vs Uni-Ball?
When it comes to off-road adventures, every component of your vehicle matters, especially the ball joints that connect your upper control arms. Two of the most popular choices for lifted vehicles, like yours, are the JBA Max 90 Ball Joint and the Uni Ball. But which one truly delivers better performance and reliability for the weekend warrior, off-road enthusiast, or DIY mechanic? Let's break it down.
Why the JBA Max 90 Ball Joint Stands Out
The JBA Max 90 Ball Joint isn’t just another component; it’s a game-changer for off-road performance. Designed specifically for vehicles that need to handle rough terrains while staying reliable during everyday commutes, here’s why it’s the superior choice:
1. Unmatched Range of Motion
With a 90-degree range of motion, the JBA Max 90 Ball Joint outperforms the Uni Ball, which only offers 66 degrees. That extra articulation comes in handy when navigating difficult trails and steep inclines, giving your suspension the flexibility it needs to tackle rugged terrain.
2. Easy Maintenance
Unlike a Uni Ball, which can demand tedious disassembling for maintenance, the JBA Max 90 is built with convenience in mind:
- Grease Fittings: Simply add 3–4 pumps of grease during regular servicing (every 3,000–5,000 miles) without removing the control arms.
- Rebuildable: If repairs are needed, you can rebuild the ball joint easily with a spanner tool in under 30 minutes.
3. Sealed for Maximum Durability
One of the biggest weaknesses of Uni Balls is their open design, which makes them vulnerable to dust, dirt, water, and salt. These elements can lead to faster wear and tear. The JBA Max 90 Ball Joint, however, is 100% sealed with a silicone rubber boot, keeping debris out and making it long-lasting—even during harsh weather or muddy trails.
4. Strength and Reliability
The JBA Max 90 is CNC-machined in-house from 4140 domestic chromoly steel, an industry-grade material prized for its durability under stress. Whether you’re climbing boulders or hitting potholes, this ball joint is built to handle it all without fail.
5. Quick and Simple Installation
Forget about wrestling with your upper control arms. The JBA Max 90 installs with just four bolts and doesn’t require you to remove the A-arms during replacement. Total replacement time? An easy 15 minutes.
6. Made for Offroad and Daily Driving
Most Uni Balls were originally designed for off-road racing vehicles, which are constantly rebuilt after each race. That’s not practical for the weekend adventurer who uses their vehicle both on trails and for regular commutes. The JBA Max 90 is made with the dual-purpose driver in mind, delivering trail-ready performance with minimal upkeep required.

“Replacing my ball joints used to be a headache, but the JBA Max 90 makes it simple. I love the 90-degree range of motion. It’s been a game-changer for tackling steep, uneven trails.” – Mike W., Denver, CO
Why the Uni Ball Falls Short
While Uni Balls are common in certain off-road applications, they come with notable drawbacks:
- Limited Motion: With only 66 degrees of motion, the Uni Ball restricts articulation compared to the JBA Max 90.
- Maintenance Hassles: To maintain a Uni Ball, you’ll need to completely disassemble the control arms, press out the worn Uni Ball, clean it, re-grease it manually, and reinstall the entire assembly. A time-consuming and inconvenient process.
- Vulnerability to Debris: The open design allows dirt and contaminants to get inside, often leading to premature wear and replacement needs.
For vehicles that double as daily drivers, this excessive maintenance and lack of durability don’t provide the practical balance that most owners need.
