5 ear axel weight ratings
Can anyone explain why if my 5th wheel has a GVWR of 10,995 lbs. the axels aren't rated at 5500 lbs each. Mine are rated at 5200lbs each which is 10,400 lbs total carrying capacity. Are these axels too light?

They're cheaper than heavier axles, those axles are heavy enough the tires I'd wager are barely adequate we put e range 16in tires and wheels on my brothers 5'er. The companies figure couple k pin weight leaving capacity for extras.- Replaced the axels on my trailer last year, front right got bent on trip. Replaced the 6000 lb axels with 7000 lb axels. The gvwr of my trailer is 12,380 lbs. It doesn't doesn't change any of the numbers but is a little more of a safety margin.
- 5,200 lb. axles are a good fit for your GVWR 10,995. Many 10,000 GVWR FWs only have 4,400 lb. axles.
You should have a good CCC.
Jerry - Old-Biscuit is correct. Also the difference between 5200 and 6K axle is just the springs in most cases. 6K axles can be 6 or 8 lug. 7K axle have a heavier tube wall and more spring rating, and are always 8 lug. Chris
- Because part of trailer weight is 'carried' by toe vehicle (PIN WEIGHT)
20% of that GVWR should be pin weight (roughly 2000-2200#)
Axles are also derated probably due to MAX Load Rating on trailer tires (See sidewall)
