2025+ Ram RHO Adjustable Rear Suspension Kit

• 2 adjustable fabricated FMI lower trailing arms, with 1.5" uniballs at the front and 1.25" rod ends at the axle
• 2 adjustable fabricated FMI upper trailing arms, with 1" uniballs at the front and 1" rod ends at the axle
• 1 fabricated adjustable panhard bar, with a 1" uniball at the frame and a 1" rod end at the axle
• 1 kit of hardware and spacers needed for installation

The RHO's rear axle is located by four trailing arms and a panhard bar. The lower arms carry acceleration and braking load, the upper arms control axle wrap, and the panhard bar holds the axle centered side to side.

From the factory, those parts mount through rubber bushings. Rubber is soft on purpose, so under hard load it gives, and the axle moves around more than it should. That flex is what shows up as wheel hop.

This kit replaces all five parts with fabricated chromoly links on uniballs and rod ends, which do not deflect the way rubber does. The result is a rear end that feels more predictable when it is working hard.

• 4130 chromoly fabricated arms and panhard bar.
• Uniballs at the front of each trailing arm and at the frame end of the panhard bar.
• Rod ends at the axle end of every link, which makes each part adjustable.
• Larger 1.5" uniballs and 1.25" rod ends on the lower arms, where the most load goes through.

Fits the 2025 and newer Ram 1500 RHO. It works with the stock rear shocks and springs.

The kit can be installed in only a few hours. Hardware and spacers for the install are included.

These FMI parts can be added to the rear of the RHO with this kit:

• Rear bump stop kit, to help handle the big bumps
• Shock guards
• Rear spring spacers, to add some lift in the rear

What does this kit replace?

Both upper trailing arms, both lower trailing arms and the panhard bar.

Do I need different shocks or springs?

No. The kit works with the stock shocks and springs.

Will it help with wheel hop?

Replacing the rubber-bushed factory parts with rigid uniballs and rod ends limits the flex that turns into wheel hop.

Are the links adjustable?

Yes. Each trailing arm and the panhard bar has a rod end at the axle, so the lengths can be set.

How long does it take to install?

It can be installed in only a few hours, with the included hardware and spacers.
