...Question, Will supercab springs fit on a supercrew? My 01 Supercrew rear springs are sagging badly, and If I'm going to replace them with some used ones, I'm wondering if I can up the payload a tad by putting in supercab or reg cab springs......

 

the spring dimensions for the regular, supercab and crew are all the same.. You can changed the number of leafs and the load rating for different models, equipment, motor and axle ratios........ I assume there are several "load ratings" available.

 

1997 - 2003 F150 rear leaf springs
