Frequently Asked Questions
Will these work with a lifted suspension setup?
These are engineered for factory ride height and geometry. If your vehicle is lifted, you'll need control arms designed for your specific lift height to maintain proper suspension angles and prevent accelerated wear.
Do I need new fasteners to install these?
Hardware is not included. You'll reuse your existing bolts at the frame and ball joint. Inspect them during install—if any are stripped or damaged, source replacements matching OEM specifications before reassembly.
What should I do after installation?
Get a wheel alignment immediately after install. Even small changes in control arm geometry throw off camber and toe, which causes uneven tire wear and pulls. A shop can dial in your suspension in about an hour.
