Project Rear End

I would think that two mono's would be wicked stiff and not allow much flex if you off road. I would think that with two your rate would be roughly twice as stiff or rough however you want to look at it. If you wanted could you use a full AAL for a four door pack or even a use second leaf of a pack to help. It would give you some of what you are looking for without the wicked stiffness. Don't know just my thinking! :)

Wow, this was a bigger project than I expected with a lot of metal fabrication.

Anyway, as you can see, I made a 5-leaf pack using the OEM 4-door leaf pack I got from LMCTruck.com, which was a lot weaker than I expected and my old mono leaf. This is a BEAST of a leaf pack, and at this point I'm thinking it may be too stiff. I might have to go back in there again and remove the cut leaf I made and just use the 3 lower thin leafs from the 4-pack and the thick mono leaf as the top leaf.

I took before & after measurements with no load and under load (my 5x10 Haulmark trailer with 2 bikes in it). I have to scavange where I put those numbers and will post them soon.

Below is the before pic under load. The Ex is looking wimpy.

BTW, Ohm, you are right, the Monos were 3" wide and the 4-pack is 2.5" wide. The U-bolts are spaced even more than 3" wide, so I don't think this width difference has any effect. It the shackle and the front frame bracket that hold the leafs in place.

Here are the Before (with just LMC Truck's OEM 4-door 4-leaf pack) no load heights:
Ground to bottom of left rear fender = 38"
Ground to bottom of right rear fender = 38"
Ground to bottom of hitch = 17-3/8"

I'm still looking for the with-load (trailer) specs, I might have lost them.

I'll take the After specs, kind of waiting for the springs to settle a little first. I hitched up the trailer this morning and the trailer doesn't even phaze the rear ride height. These are some strong springs!
