Hi Barney!

Any of the single axle kits you listed will work just fine for your single axle trailer. The main differences between the kits you listed is their height and how they install so I'll list out the differences below and you can decide from there which option is best for your trailer.

- 1-1/2" Front, 7/8" Rear (4-1/4" or 4-1/2" clearance between trailer frame and axle)
- Kit # APS1

- 1-1/2" Front, 1-1/4" Rear (4" or 4-1/2" clearance between trailer frame and axle)
- Kit # APS2 (single bolt to frame for rear hanger)
- Kit # APS3 (two bolts to frame for rear hanger)

- 3-1/4" Front, 1-1/4" Rear (5" or 5-1/2" clearance between trailer frame and axle)
- Kit # APS4 (two bolts to frame for rear hanger)
- Kit # APS5 (weld to frame for rear hanger)
