What you get up front

• BDS long-arm control arms — engineered to maintain factory caster and suspension geometry, so your steering feel and handling stay predictable at 4 inches of lift.
• Front coil springs — rated for the new ride height and payload demands.
• Adjustable front track bar — keeps centerline true and eliminates bump steer.

Out back

Important notes
