2027 Ram TRX Adjustable Rear Suspension Kit

Description

Every rubber bushing in the factory rear end is a part designed to move. That compliance is what makes the truck quiet on pavement and what makes it feel vague and prone to wheel hop when you are pushing it.

This kit replaces the factory upper and lower trailing arms and the panhard bar with adjustable fabricated 4130 chromoly components on uniballs and rod ends. Compatible with stock shocks and springs, and it installs in a few hours.

What the Kit Changes

Replacing the factory rubber bushings with rigid race-grade bearings makes the rear suspension more predictable and reduces the unwanted flex that leads to wheel hop.

  • 4130 chromoly steel construction throughout
  • Uniballs and rod ends in place of rubber bushings — the axle goes where the arms put it
  • Adjustable, so pinion angle and axle position can be set rather than accepted
  • Works with stock shocks and springs — this is a linkage upgrade, not a whole rear suspension replacement
  • Installs in a few hours

What's in the Kit

  • (2) Adjustable fabricated FMI lower trailing arms — 1.5" uniballs at the frame, 1.25" rod ends at the axle
  • (2) Adjustable fabricated FMI upper trailing arms — 1" uniballs at the frame, 1" rod ends at the axle
  • (1) Adjustable fabricated panhard bar — 1" uniball at the frame, 1" rod end at the axle
  • Complete hardware and spacer kit for installation

The panhard bar — also called a track bar — is included here, so you do not need to buy one separately.

Add-On Options

For more performance in rough terrain, these pair with the kit:

Fabricated or Billet Rear Arms

Two ways to get the rubber out of the rear end:

  • This kit — fabricated 4130 chromoly, adjustable, and it includes the panhard bar. The choice when you want to set axle position rather than keep the factory geometry.
  • Billet rear arm kit — CNC machined aluminum, raw or anodized, stock length, panhard bar sold separately. The choice when the finish matters.

Fitment

2027 Ram 1500 TRX, with stock shocks and springs.

The 2021, 2022, 2023 and 2024 TRX is a different generation and uses its own kit. Ram did not build a TRX for 2025 or 2026, so a part listed for 2021-2024 does not carry forward to the 2027 truck.

Questions

Is the panhard bar included?

Yes. The adjustable fabricated panhard bar is part of this kit — five pieces in total with the four trailing arms.

Do I need different shocks or springs?

No. The kit is fully compatible with stock shocks and springs.

What is wheel hop and does this fix it?

Wheel hop comes from the axle winding up against soft bushings and releasing. Removing the rubber and the flex is what reduces it.

How long does it take to install?

A few hours. It is a bolt-in linkage swap, not a fabrication job.

Trailing arms or control arms?

Both names get used for these. On this truck the rear links are trailing arms — upper and lower pairs running fore and aft, plus the panhard bar across.

Does this fit a 2021-2024 TRX?

No. See the Fitment section above for that truck's version.
