PART NUMBER: FR34S. Skyjacker Softride springs taper over the entire width of the leaf creating more flex at the leaf ends. This tapering distributes loads more evenly over a greater area and reduces the tendency for one leaf to dig into the leaf above it.
Skyjacker FR34S leaf springs fit great! Maybe one of these days I willl get an engine and go drive hte truck so I can feel how they ride. The Ranger Station highly recommmends them though, so I feel good about the purchase.
Much better ride than my stock springs with add-a-leaf. The problem is the overload leaf almost touches the leaf above it and they rattle like crazy on rough roads. Overall, happy with them and would recommend.
