So i bought a lift kit about a year and a half ago and the guy had told me it was 5.5 which came off of his truck. The arm and springs are Fabtech but i dont know what the spindle make is. The part number says FR 300 and cant find anywhere. Does anyone know who makes a spindle with that part number and if it actually is a lift spindle. Still havent put it on my truck yet.

 

well if it was a complete fabtech 5.5 kit.. id say it was fabtech.. makes sense right?
