You really should check out Flexi-ride axles. You still have a rubber torsion independent
axle that can be ordered for whatever
weight you would like, plus you can easily change the height of you trailer and also side to side adjustment for uneven loads by just removing one bolt per side to place the spindle arm to a new location on the 80 splined
axle, so you can still get into the garage and go off-roading.
