FX4 v.s. 4X4
Nope. Assuming you have the 4x4 Offraod package your truck would be better. The "Rancho" shocks are valved the same as the shocks that came on every 4x4 with the towing package. They are just painted white. Tenneco Automotive makes the OEM Motorcraft shocks and Rancho shocks. So the FX4 Ranchos are not the same as any aftermarket Rancho. They were valved to Ford's specs. They were just a marketing ploy by Ford.
With the rear end off the ground, and the tranny in neutral, spin one of the rear tires. If both tires spin together, you have limited slip. I believe it was included with the Off Road package along with skid plates.
