I just had my triple axle trailer flipped and all new spring hardware installed. At least now I can properly lube the suspension and have the piece of mind that the shackles won't snap or wear thru. Since I lost 2 tires on the way back from G over last T-Giving. They were probably rubbing in the wheel wells or could have failed due to age. Since buying new tires I wanted to take any precautions.
The axles have a 3 degree camber so you have to weld on new spring perches, so it’s not just flipping them to the bottom of the springs. You need longer center spring bolts if you have shocks so you can re-use the existing tieplate/shock mounts between the spring and the axle otherwise longer shocks will be needed. New U-bolts and hardware are a good idea and of course the new equalizers and HD hardware.
Yes, generally around $400 for a tandem axle. A little more for a triple. I paid $600 and that included pressing the new spring sleeves, spring perches, U-bolts, tieplates etc.
Here is the kit I bought.
