2025+ Ram RHO Rear Suspension Arm Kit - Billet Aluminum
Description
Description
A billet aluminum rear suspension arm kit for the 2025 and newer Ram 1500 RHO: both upper and both lower arms, built to fit the factory mount locations. Every arm runs 1" FK uniballs with custom machined 17-4 stainless steel spacers.
Doing the uppers and lowers together replaces all four trailing arms in one order. The lowers carry acceleration and braking load, the uppers control axle wrap, and a urethane wobble stopper at the front mounts keeps the arms in alignment.
What Is In The Kit
- 2 FMI billet aluminum rear upper arms with spacers and hardware
- 2 FMI billet aluminum rear lower arms with spacers and hardware
This kit does not include a panhard bar upgrade.
Why Replace The Upper And Lower Arms
The RHO's rear axle is located by four trailing arms. The lower arms push the truck forward and hold the axle under braking. The upper arms stop the axle from twisting and hold pinion angle.
A rubber-bushed link deflects a little every time load goes through it. A uniball pivot does not, so the axle stays where the arms put it. Replacing all four at once means none of the trailing arms are left as the soft point.
How It Is Built
- Billet aluminum upper and lower arms.
- 1" FK uniballs at the pivots.
- 17-4 stainless steel heim spacers, custom machined to fit the stock mount locations.
- Urethane wobble stopper at the front mounts to keep the arms in alignment.
- Aluminum ball post on the upper arm for the suspension travel sensor, so the truck continues to work correctly.
