I cant remember how much I paid for front and rear sorry.
The other thing you may want to look into is some kind of power chip that can correct your speedo. When I had my gears done I did a K&N cold air intake and a edge power chip at the same time.
I went out about a month ago, and found a Toyota TRD stuck in the mud. He asked if I thought I could make it through the same spot he got stuck. The TRD was probably on like 33's. With 4x4, my 37x12.5R17 BFG KM2's and 4.88 gears I powered right on through his spot with no issue.
