If you drive a 2002–2006 Acura RSX (DC5), you already know how capable the chassis can be. But once you start modifying ride height, especially with coilovers or a lift setup, the factory rear suspension geometry can fall out of spec. Uneven tire wear, unstable handling, and alignment limitations often follow.
Upgrading to adjustable rear lower control arms is a straightforward way to restore proper geometry and improve stability. In this guide, we’ll walk through why the upgrade matters and how to install the MaXpeedingRods rear lower control arm kit designed specifically for the RSX platform.
Why Consider Rear Lower Control Arms?
When you raise or modify your suspension height, the stock arms may no longer maintain correct alignment angles. This can lead to excessive camber or toe changes that affect traction and tire life. Adjustable arms help reposition the suspension correctly and allow proper alignment after modifications.
The MaXpeedingRods kit includes two rear lower control arms with an eye-to-eye length of 280.5 mm, engineered to directly replace the factory components. The design supports vehicles raised approximately 4.5 to 6 inches, making it suitable for lifted or performance setups.
Before You Start
Always work on a flat surface and follow safe lifting procedures. The instructions recommend that installation be performed by qualified personnel and that you refer to your OE service manual for proper torque specs and procedures.
You will need:
- Jack and jack stands or lift
- Basic hand tools
- Factory bolts and nuts (reused)
- Torque wrench
Step-by-Step Installation
First, raise the rear of the vehicle and safely support it. Remove both rear wheels and tires for access.
Next, remove the factory rear lower control arm from the car body. Keep the original hardware, as you will reuse it for installation.
Position the new MaXpeedingRods control arm into place and install it using the factory bolt and nut. Torque all fasteners to OEM specifications. Repeat the same process on the opposite side.
Once both arms are installed, reinstall the wheels and lower the vehicle back to the ground.
Final Checks
A professional alignment is strongly recommended after installation. Any suspension change will affect alignment settings, and proper adjustment ensures the best handling and tire longevity.
It’s also a good practice to periodically inspect all nuts and bolts for tightness, especially after the first few drives.
The Result
With upgraded lower control arms, your RSX will feel more planted and predictable. You’ll gain better alignment flexibility, improved stability during cornering, and more consistent tire wear. For drivers running coilovers or a lifted setup, this upgrade helps the suspension work the way it was intended.
If your rear end feels unstable after height changes, this is often the missing piece. A simple bolt-on solution can make a noticeable difference in both daily driving and spirited use.
