Rear Suspension , new shock question
I bought my truck its an 06 F250 XLT. It has in the front What looks like a red spacer between the coil, i know its a leveling kit, but dont know by how much, the truck sits real high, and I like it, it also has in the front 5100 shocks bilstiens. The Rear appears to be 4" blocks with stock shocks. the truck has a gvwr of 10,000lbs on the side door. But i want to know if these blocks are stock or the 350 ones. I want to put 5100 in the rear but dont know which ones i should get, any help and input would be appreciated, i dont wanna throw money and it be the wrong shocks. the truck sits almost completely level.
