Hey there Troy, A Dexter EZ Lube axle ordered from a local trailer sales & supply shop; The axles are 5 on 4.5 so I used 2” wheel spacers converted to 6 on 5 to fit the stock LX450 Wheels 16” wrapped in 285/75/16s ATs. The springs I finally have now after snapping a three leaf 3,500 lb set are 5 leaf 5,000 lb . This week I’ll be installing the dexter upgraded spring shackles with greasable bolts and bushings. Last time out we snapped the left side shackles after a few hundred miles on wash board. Foolishly I didn’t air the trailer tires down enough and the shackles gave way. Good luck
