Does anyone else own the 2012 Attitude FL28AKLG

Trying to rate leaf springs by the number in the spring pack is a hit or miss way of doing things. If you can find the manufacture of the springs and look at spring charts provided by them might work. A little searching on the net will find 26" springs with 4 leafs rated at 3000lbs, the same chart had 3 leaf springs rated at 3000lb also. These were 1.75 width, which is pretty standard. I also saw 3000lb springs with 5 leafs so it's pretty much a******shoot trying to rate springs that way. I ended up just ordering springs that had a rate as close to axle capacity I could find.

A suggestion:

Get your frame number -it should be on a plate welded to the side of the PIN Box mount. Call Lippert Tech and ask for a suspension and axle "Build" Sheet to know the component part numbers thus their capacities.

After you get this information call them again and ask what range of GVWR's the frame could be configured as a tandem or triple axle.

This will get you some baseline info to plan upgrades to meet your situation and beef up where needed to prevent failures.

Don't see any numbers on the pinbox except the VIN.
I set an email so we will see what they say.
Thank you for all the info !

Thank you for the info.
Mine is not reinforced, just a big "U" shaped triangle.
Someone else had suggested welding a plate across the legs of the "U".

Any thoughts on the springs being way under-rated when compared to the axle ?

Yes, many.

Goes back to this trailer model having a pretty low Factory GVWR. Some component in the trailer assembly, spring, wheel, tire, frame, floor structure and or other unknown factor is causing Eclipse RV to limit the GVWR on that model as manufactured.

Seems kinda crazy to have such a light weight spring (2200lbs).
If a person had it at max load of 11,900lbs and had a 20% pin hitch weight of 2380lbs that would leave you with 9520lbs of weight on 8800lbs rated springs.

I am no genius but that doesn't add up or make sense for either Lippert or Eclipse, whoever decides what springs go on this thing.

Would agree but am betting the springs are 2500 or 2600 rated / each depending on if Al-Ko or Lippert. Could be either on a Lippert frame assembly.

Most springs are rated in pounds per inch of travel, so at one inch deflection this spring would support 2200#, at 2" deflection 4400#, etc. I'm not real familiar with trailer springs so don't know if this hold true or not.

Looking at Factory numbers.

11900 GVWR @ a Pin Weight of 20% (2380) = expected maximum axle 9520

9520 / 4 = springs @ 2380 each

Running the numbers at the factory PIN percentage calculated from dry weight:
11900 - 2844 = 9056
9056/4 = 2264 per spring

From a minimum engineering/product cost stand point @ GVWR rating a 2400# spring could be specified pretty easily.

Can a couple guys check out a couple things for me ??

I was told by a local trailer builder/shop the middle spring equalizer should be a rectangle and not the same as the end hangers, per DOT requirements.

Mine has an end spring hanger in the middle position.
Does everyone else have the same thing or is mine "special" ?

-

Also was told the four leaf pack springs are rated at 2200lbs each.
The same trailer builder/shop said the springs should meet or exceed the axle ratings, per DOT requirements.
Anyone have anything other than the four leaf springs in each pack from the factory ?

Begining to wonder if the shop knows what they are talking about and my trailer is not up to spec or if they are quoting old requirements or requirements that do not pertain to campers...
