Question:
I have a 2015 Chevrolet Silverado 3500 HD. I am interested in the RAS active suspension upgrade. My vehicle has a smaller helper spring factory stockabove the main leaf spring. Seems like it might be in the way for this install.

Hey Victor, we actually have a version of the Roadactive Suspension kit that was designed to fit th models of the 2015 Chevy Silverado 3500 that have the factory top overload springs with the part # RAS3611-CHD so that would be the kit you'd need. Have you heard good things about the RAS kits? We are big believers in how well they work here for sure.
