So Dave, I noticed you have bounced around on the leaf springs. I had to do the same thing, very frustrating. I started with OME Dakar, then I added a leaf. After a year they looked flat so I called ARB to complain. They sent me a new set for FREE and said they should not be that flat yet. As soon as I put the new Dakars on I noticed they were flat as well.
I finally finished out with an 11 pack from Deaver. These things are AMAZING, and they are always smiling no matter what I put in the bed. Strangely they still flex on trails even when the bed is empty.
Where are you headed next in the spring department?
I have gone around on springs too much but that's the joys of having a truck build that evolves as much as mine has. I had a "custom" Deaver 12 pack that was quite flexy but worthless IMHO for carrying weight full time like I do.
I've been working with AllPro providing input on what the next spring would be. I have a new set here in my garage now that I'll be putting on next weekend
I'll post pics then but for now I'm happy to announce here on American Adventurist that they will be offering these new APEX Premium springs soon. Made in USA with about 1/8 inch wider leaves and nearly 13% higher spring rate than the APEX Heavies I have on the truck now (FS BTW!).
Stay tuned for pics and details.
