Rear Axle Suspension Enhancement Kits for 2011 Ford F-250

The type of suspension enhancement that will work best for your 2011 Ford F-250 depends on what the specific handling issue is and on how you typically use the truck.

For instance, if you routinely use the truck for heavy cargo loads carried in the bed and the problem is the suspension bottoming out on rough roads then a jounce spring kit such as # TFR250SDG from Timbren would be appropriate. This kit consists of two independent rubber jounce springs that engage only when the axle is under a load; they provide progressive resistance, becoming stiffer as the load on them increases. They do not alter the vehicle's unloaded ride quality. This kind of bolt-on kit is easy to install and requires no maintenance.

If your goal is to make trailer towing smoother then I would suggest an air bag kit and compressor that will allow you to adjust their pressure (while you drive) to find the sweet spot for any given trailer load. Firestone Ride-Rite air spring kit # F2597 along with Air Command compressor # F2097 would be ideal for 5th wheel or other towing applications where tongue weight/pin weight causes sagging in the rear.

If neither of the above conditions applies then the RoadActive Suspension kit # RAS3611-S, which has a lighter weight capacity of 2000-lbs, would be a good choice since this kit also engages only under load and also offers bolt-on installation and no required maintenance.

The linked articles will be useful as you decide which kit is most appropriate.
