Frequently Asked Questions
Why fit adjustable upper control arms to a lifted Navara?
A suspension lift changes wheel alignment. Adjustable arms provide additional camber and caster correction to help achieve suitable settings for your vehicle.
Is a wheel alignment required after installation?
Yes. Blackhawk requires a wheel alignment immediately after installation. Fitment should be completed by a qualified mechanic with specialist 4WD suspension knowledge.
Do the ball joints require maintenance?
Yes. Grease the ball joints before installation and at regular service intervals. The adjustment threads must remain unlubricated, as specified in Blackhawk's fitting instructions.
