I have had a lot of people ask me if this will fit my truck or not and thought I would provide a little more information. To find out what models fit your truck, please visit the Firestone Ride-Rite web site to identify the part number necessary for your truck. You will also not find the 2450 model number out there any more because Firestone actually created a new part number, 2550 which is actually a replacement for Kits 2520, 2450, and 2330. I know these fit the 2008-2010 Ford F250/F350 trucks as that is what they were designed for and there is a good chance that they will fit F250/F350 trucks with gasoline engines requiring the 2550 kit. If the kit required for your truck is not a 2550, 2520, 2450, or 2330 than there is a good chance that it will not fit (for example if you just happen to have a 2012 F350 CC DRW - 6.7L PSD that requires a 2535 kit, than not this will not fit because of the DEF tank). To validate if the 2450 will fit your truck, you could contact Firestone.

If different brackets are needed (which might be an inexpensive add), they can also be ordered through etrailer.com as they carry most everything necessary.
