Control Arms, Bushings & Mounts: Factory-Direct Guide
Lowered cars often need adjustable arms to fix alignment, and worn rubber bushings and mounts make a car feel loose. Here is what these parts do and how to buy them direct.
Adjustable control arms
Adjustable camber and toe arms let you bring alignment back into spec after lowering. Look for quality steel or forged arms, sealed rod ends or spherical bearings, and clear instructions. They must be set by an alignment shop after install.
Bushings and mounts
| Type | Feel |
|---|---|
| Rubber (OEM) | Quiet and comfortable; wears over time. |
| Polyurethane | Firmer and sharper, with more vibration. |
| Solid / spherical | Most precise and noisiest; mostly for track. |
Before you order
- Confirm the exact chassis code and model years.
- Ask what material the arm and bushings are made of.
- Check if hardware is included.
- Plan for a professional alignment after install.
