Has anyone really tested out the TJM HD springs on their d40? I saw a couple posts using Google, but nothing more than "I like them, they a little rough, settle after a couple weeks, etc etc."
I'm looking for honest long term review and if you off-road at all and have used them while being really loaded down in the bed

I had these on my Frontier for a few years. I feel like their construction, much like the oem leafs, 'leaves' much to be desired. Their design, regular leafs and overload leafs has its drawbacks. In their early life I felt I needed to add weight so they wouldn't beat me up each drive. Loading the truck up gave the smoother ride I was looking for, at the expense of gas and wear and tear on the truck. After a while I was riding on the overloads all the time. It didn't matter how loaded or unloaded I was. I had a backache after any longer drive. Greg at PRG suggested I remove the overloads and add air bags to act in their place. This improved the ride, and I had the ability to adjust the air bags to match the load I was carrying. Unfortunately without the support of the overloads, I ended up developing a crack in the second from the top leaf on the passenger side.

I ended up ordering Alcan's to take their place. After weighing my truck at a CAT scales and passing on this info to Bill at Alcan, he said they were the correct weight, just not the best design. Bill made me a pair of 8 leaf progressive leafs. +600 pounds at 2" of lift. I also kept the air bags in, for when I'm towing also, or I have my slide in camper in the bed.

That being said, I have an Xterra also. I bought it earlier this year it has the stock leaf packs with the PRG 2 leaf add-a-leaf and the overloads removed. It is leaps and bounds better than the stock setup.

If I was you I would consider trying an add-a-leaf or a progressive leaf pack, like Deaver's or Alcan's. I'm not sure what you're trying to accomplish, or your budget. Both should weigh on your decision.

I hope this is comprehensive enough. Please, if you have any other questions just ask. The link in my signature may have more helpful info. Unfortunately The photos are missing because of Photobucket.

This does help. And I appreciate the time you took and extensive response you gave. Unfortunately I think my springs are already too far gone for an aal to add any benefit, even with the overload spring in.
I'm looking for articulation and being able to carry some more weight. I know one may be a trade off for the other but it's worth a shot.
I haul fire wood and other household stuff all the time and it's taking it's tole on the second set of leafs already. I got them replaced at 33*** miles and at 43*** miles the new set is already flat and on its way to being inverted.

The alcans and other higher quality leafs are unfortunately out of my price range. Unless I saved for like two years.

I'm glad I was helpful. I hear you about the cost of Alcan's. It was a little over $800 shipped for the set. I think that included new U-bolts.

I think you will find that you will be a little under $600 shipped for TJM's, if you can find them. TJM is having a difficult time keeping stock in North America.

I looked into local spring shops as well. Unfortunately the most reputable shop in my area could only provide OEM rated springs. They were priced similarly to the TJM's, about $400. The benefit of locally made is that you get to skip the shipping cost. It is expensive to ship any leafs.

You may have better luck finding OME leaf packs. There are far more people running them. Chris or Steve at Nisstec can help you as well. They have experience with Alcan, OME and TJM. They are who I bought my TJM's from.

I have a summit racing close by, so if I ordered through them I could just pick them up.
I'm going to do more research and see what I'm going to have to do to get this issue resolved from a more permanent stand point
