This kit will physically bolt up to an RWD F150, though you will get more ride height out of them than what they're rated for on the 4WD trucks. The stock UCAs will probably be fine if your truck's primarily used on the street. If you are off-roading and articulating the suspension, you may want to consider UCAs. We do recommend using either a 1.5" rear block or 4WD take-off rear blocks with the rear shocks to keep them in an optimal travel range.
