OUO Dealers can source these non OUO items from wholesale distrubuters.

Track Rod Joint Options

You can simply adjust the OUO track bar fully istalled. You don't need to remove the track rod to get the axle straight under the truck. We include an OUO wrench so you can torque the jam nuts. There is also a set screw lock on the joint threads.

Joint Description Replacement Cost Mile Zone Service Needed?
OE Bushing OUO Joint has a cushion to adsorb harsh road impacts Low 100K No
Teflon FK Joint is the aftermarket industry standard. It has no cushion to adsorb harsh road impacts. We add a seal to keep the water out. Water and grease will ruin the Teflon liner in these joints. Do not grease a Teflon Joint. High 25K No
Chromoly OUO Joint will last a very long time. It is nearly indestructible, but it will need to be greased and tightened at the spanner ring every 20k. It has no cushion to adsorb harsh road impacts. Rebuild for Low Cost 200K Yes
Isoball OUO Joint gives you the smooth movement of the Teflon joint but with a cushion to keep the Teflon liner in the joint from pounding out High 100K No


At the axle end of the OUO track bar we keep the factory Ford joint in the axle housing. We do this for many reasons. They are strong, the same joint is used in the F550s and millions of Ford trucks since 2005. Yes, they are a wear item, all joints are, but they are robust and last a long time. They do not need maintenance. They can be replaced correctly, at a very low cost by any shop in the country with no special instructions. Might not seem like a big deal, until it is a big deal.

One Up Offroad's Steady Axis™ Steering with OUO's Steady Track™ Stabilizer

  • OUO's Steady Axis™ Steering refines the geometry of the front suspension components. Taking into account all of the factors of the radius arms, drag link, track rod, shock travel, three-dimensional axle housing, and knuckle paths to get the lowest bump steer possible. Going beyond "good enough" and optimizing the system to get it perfected.
  • OUO's Steady Track™ Stabilizer moves the high mount steering stabilizer off of the drag link and onto the pitman arm. This design change gives a higher level of confidence in the steering performance.
  • This 2.5in Lift System has been optimally designed to give the best possible steering geometry. We don't even call this a level kit because it is much more than a level kit.


There is more to the front suspension of solid axle trucks than trying to make the bars the same length and the same angle. No matter how many magazines say it, or internet experts repeat it, the "same length / same angle" is not the correct mathematical equation to make these trucks not have bump steer. "Same length / same angle" is an overly simplified answer to a complicated equation. Also, we know you can't just move the track rod location over an inch to make the factory track rod work and not suffer negative consequences of increased bump steer by changing that geometry. Just like putting on a 2" dropped pitman arm with no other matching components is a horrible idea. Usually the lowest cost is not the best way to get a top of the line truck to drive well. One Up Offroad has never set out to build anything lowest cost, instead we have always strived to make the best product possible and let the cost be where it may.

When a truck is not lifted, having the steering stabilizer attached to the drag link is some-what functional because the angles between the two are closer to horizontal. As you raise the suspension you increase the angle of the drag link. When the suspension cycles, that increased angle is trying the be held straight by steering stabilizer that's moving on a completely opposing arc. These opposing arcs cause the steering stabilizer to induce bump steer by forcing the drag link to follow the arc that it is mounted on and not the arc of the track rod. The Fox ATS Adjustable Steering Stabilizer is an amazing design. The pass thru shaft design works really well, is effective and the adjustability makes this an excellent unit. However, if it is put on a lifted or leveled truck it will amplify the bump steer. To fix this problem we invented the Steady Track System. Our patent pending and trademarked Steady Track System™ moves the mounting of the steering stabilizer off the drag link onto a bracket on the pitman arm. This eliminates the suspension movements from affecting the steering stabilizers directional control. Refining these details gives a more stable feel to the steering wheel.

The steering geometry is refined and optimized by OUO's Steady Axis™ Steering: Longer than stock track rod mounting pushes it outside of the frame rail and into the path of the sway bar. Relocating the sway bar forward gave room for the new track rod location and for larger tires to go into the clearance area of the sway bar. It's all the fine details put together to make big improvements. Years of development and testing went into this design to make your trucks drivability better.

Trucks with solid front axles have the highest un-sprung weight in any automotive class. When you take off the 20 inch factory wheel and put on a 26 inch wheel you increase that un-sprung weight. When you take an 8 in sidewall height and reduce it to 3 inches it removes a tremendous amount of ride quality. When you run 60 pounds of air in your tires it makes the truck right very harsh. Large wheels and short tires will make it so you feel every bump in the road like it's twice as big even if you have the absolute best tuned suspension. It's unrealistic to think anyone can tune a shock to make a heavy-roller with metal wheels drive like a luxury car.
