Frequently Asked Questions

Do I really need extended upper control arms after lifting my truck?

In most cases, yes. Lifting your truck changes the suspension geometry, causing the upper control arm ball joint to operate at an extreme angle. This can lead to premature wear, poor alignment, and reduced ride quality. Extended upper control arms correct this angle, restoring proper ball joint travel and extending component life. We recommend them for any lift over 2 inches.

What is the difference between a ball joint and a uniball upper control arm?

A ball joint uses a stud and socket design similar to OEM, offering smooth operation and noise isolation. A uniball (spherical bearing) provides greater misalignment and articulation, making it better for off-road flexing. However, uniballs can transmit more noise and vibration and require more maintenance. Your choice depends on your primary use: daily driving or off-road performance.

Can I install extended upper control arms myself?

Many extended upper control arms are designed for bolt-on installation and can be a DIY project if you have basic mechanical skills and tools. However, you will need an alignment after installation. Some designs require removing the coilover or strut, which can be challenging. We recommend consulting the manufacturer’s instructions and considering professional installation if you are not experienced.

Will extended upper control arms improve ride quality?

Yes, when properly selected for your lift height, they can improve ride quality by restoring the ball joint to its optimal operating angle. This reduces binding and allows the suspension to move freely. However, some designs (like uniball) may introduce more road noise. For daily driving, look for arms with rubber or polyurethane bushings for a quieter ride.

How do I know what lift height my upper control arms are designed for?

Each product specifies a recommended lift range (e.g., 0-3 inches). It is important to choose arms that match your actual lift height. Using arms designed for a different lift range can result in improper geometry and may not correct ball joint angles adequately. Always verify compatibility with your specific lift kit and vehicle model.
