asked by: Kevin L
Helpful Expert Reply:
The correct RoadActive Suspension Custom Leaf Spring Enhancement Kit for your 2002 Ford F-250/350 is the part # RAS3611 for the Standard Duty or # RAS3611-HD for Heavy Duty, which offers an extra 1,000 pounds of capacity.
I don't believe there is a part number stamped onto these units so what you can do is compare the used set you're looking at with the images we have of these on the product pages or even send me a picture directly and I can try to verify. If you want to be safe though you can always purchase these brand new and you know they are a confirmed fit for your truck.
I have attached a couple short video demonstrations that you can check out as well.
