"Bolted the SSR-130-47 onto my E-450 in under 30 minutes. Loaded the box truck for a delivery run and the rear stayed level the whole way. No more squat at the bumper, no more bottoming out on driveway dips. No air lines, no compressor, nothing to maintain. Easiest suspension upgrade I've ever done."
