Nice. I didn't realize you could get those big 12" trailer brake drums in 6x5.5; just assumed they were all 8 lug. Should be a pretty bulletproof setup.So I got what I feel is a pretty good price for a 66" Dexter #5000 axle, 6x5.5 bolt pattern with electric brakes and top mount spring perches. $460 shipped unassembled.
Here's my previous trailer with spring under axle and old skool GY MTR 245/75R16 tires:
It looks like you could fit your 32s with it spring under if you needed to get it lower.
