Frequently Asked Questions
Do these work with any lift kit, or just certain brands?
These are designed for 2–4" lift applications. Confirm your lift kit height before ordering—oversized lifts may require different geometry arms. Compatibility depends on lift amount, not brand.
Will I need new hardware or ball joints to install these?
The arms themselves use factory mounting points. Ball joints and hardware are not included—you'll need to source them based on your vehicle's service manual requirements or have a shop assess what needs replacement during installation.
Can I install these myself, or do I need a shop?
Installation requires basic hand tools and a jack, but suspension work demands precision. Improper angle or torque settings can cause alignment issues and premature wear. Professional installation is strongly recommended.
