🚛 Elevate your haul game—stronger, steadier, smarter suspension.
The RAS RoadActive Suspension 3611-HD is a heavy-duty rear leaf spring upgrade designed for Chevy/GMC 2500&3500, Nissan Titan, and select Ford trucks (2009-2014 F150 2WD, 1973-2010 F250). It boosts rear suspension strength by 40-50%, reduces rear squat by up to 3 inches, and enhances handling by minimizing sway and body roll.
