I was wondering if anyone with a heavy load had any more images? I did order these springs and I am waiting to get my truck back from Bowens Customs to install them, but i need it bad. IM SAGGY.

Badass rig man! We just weighed in at 10,160lbs fully loaded so we've probably got ya beat! Our HD springs were hurting pretty bad!

Wowza! Is that the RSI rear bed replacement?

Thanks man, I will not sleep while its in transit to me! I do not think I will be there, I am thinking I will be there. I estimate without a small overland trailer, and all my gear the truck is like 400 over factory. But most of that is in the rear, and currently no spare tire. I am just hoping it works out.

Similar, its made by Bowen Customs in Colorado. American Made.

That's a sick rig man.

Thank you! These HD springs are going in today fingers crossed they are enough.

My rig has about 400-500lb in the bed between the camper shell, decked system, and other items. I also have the Eibach front springs and it's all on 37s. It sit's with about 1/2" to 1" of rake, though it's hard to tell.

 

[ScarlettHogg]

Thanks for the share, yeah mine definitely helped, I think I am unfortunately also battling wheel well issues on my flat bed.

Which Eibach springs are you running up front? And would you be able to share a side profile picture?

I’m about to install the HD rears along with a SmartCap, Decked Drawer System, roof rack, Rhino Batwing awning, and some static cargo. Pretty similar build to yours, though I calculated my setup at closer to 700 lbs.

I’m debating whether I should add Eibachs in the front as well, or if that would just end up causing squat.

You'll probably end up with squat with the Eibachs up front. I have the 1.6" and I've noticed my truck is just baaaarely level with my normal 400lbs in it. I have a sneaking suspicion that the HD springs break in a little bit as the truck seems to sit lower nowadays than it used to.

The pic from the mountains is probably 500-600lb in the bed, it was for sure squating. The one with the mud is way more than that, probably 700-900 with the dirtbike on the back.

My front springs are Stock with a FMI Leveling kit. The weight does not impact the front at all so I would say what ever you want to do for looks.

Id agree, my seem to be a littles less aggressive as well. Better than stock

Oh for sure.

I was going to email Eibach and see if they could send me a free length measurement to compare mine to, that way I could periodically check for permanent sag. I may also trim my front springs or go back to OEM in the front to get a slight bit of rake back. I want to install a rack on my camper shell but it's just too much weight at the moment.

I may also follow your lead and add the spacers to the rear.

I really appreciate all the responses! And love all the pics!

Yeah, so it sounds like for now I am going to avoid touching the front, because it seems like the rear is going to need all the help it can get to at least have a rake, or at most level, but I don't want to squat.

I do wonder how upgrading to 37's changes all these considerations and calculations. I would think with 37's I would gain about inch or so of height?

Once I get it all setup, I will report back.

on a side note, I was considering a drop diff kit from ontrack.

My truck is on 37x12.5 R18s for some perspective. It does raise the truck about 1". I wish I had gotten the 13.5s though.

oh ok, you know what, I knew that!

So just to recap: you’re on 37s, running the 1.6" Eibachs up front and the HD Eibachs in the rear.

From what I can see, with your static load of around 500–600 lbs the truck sits pretty level, but anything beyond that starts to show a bit of squat?

I have the decked system and probably ~300lbs at all time in the setup. It almost seems like there is a bit of reverse rake now. I wonder if getting the HD springs for the rear only will get it more level or even a slight bit of rake? Any difference in the ride quality? I am on factory with everything else. I am also considering a diamond back HD cover.

Not quite that much normally rolling around.

The Smart Cap is 235lb, the Decked is 208lb, so that's 443lb added. The Vossen spare is 28lb while the OEM wheel is 30lb. The 37x12.5R18 Toyos are 79lb each while the factory Goodyears are 63lb, so that adds another 14lb for a total of 457lb normally riding around with me.

The pic in the mountains had maybe another 100lb of recovery gear in the drawers.

But yes, HD rears, 1.6" fronts on 37s.
