Frequently Asked Questions
Why upgrade the upper control arms after a suspension lift?
A lift changes wheel alignment. Adjustable arms provide additional camber and caster correction to help restore suitable settings for your vehicle.
Is a wheel alignment required after installation?
Yes. Blackhawk requires a wheel alignment immediately after fitting. Installation should be completed by a qualified mechanic with specialist 4WD suspension knowledge.
Do the ball joints require maintenance?
