Description
These billet aluminum upper control arms bolt onto the 2021-2024 Ram TRX and replace the factory arms and their rubber frame bushings with adjustable FK rod ends and a 1.25" FK uniball. The result is tighter, more predictable handling and wear parts you can replace without buying a whole new arm.
Each arm is CNC machined in-house at our Mesa, Arizona shop and works with the stock spindle.
Why Upgrade the TRX Upper Control Arms
- Tighter handling. Rod ends replace the rubber bushings at the frame side of the arm, so the front end feels tighter and more predictable.
- Adjustable caster and camber. The 7/8" FK rod ends at the frame let your alignment shop dial in the front end, including after a leveling kit.
- Serviceable. When the 1.25" uniball or 7/8" rod ends wear, replace just those parts instead of the entire arm, the way you would with stock arms.
- Direct bolt-on. Works with your stock spindle.

FAQ
Do I need upper control arms on a leveled Ram TRX?
Adjustable upper control arms let your alignment shop set caster and camber after the truck is leveled, and they replace the rubber frame bushings with rod ends. Pair them with a TRX front leveling kit or run them at stock height.
Are these TRX upper control arms bolt-on?
Yes. They are a direct bolt-on upgrade that works with the stock spindle. Have the front end aligned after installation.
What ball joint do these arms use?
A 1.25" FK uniball at the spindle and 7/8" FK rod ends at the frame, all with 17-4 stainless steel spacers.
Can I replace the uniball or rod ends later?
Yes. The uniball and rod ends are replaceable, so you service the wear parts instead of replacing the whole arm.
Do these fit the 2027 TRX or the Ram RHO?
No. This kit is for the 2021-2024 TRX. The 2027 TRX and the RHO each have their own kit, linked under Fitment above.
