Here's the rear Air Ride Street Challenge suspension system and Currie 9+ rear axle housing going in... it's only the axle housing because a major shipping company (to remain nameless) "lost" 33 spline axle... Other than that, no major hiccups with the install. We chose to weld in the upper air spring brackets to make it a little cleaner.
