That makes sense... my truck is always loaded.

I've never tried the Terrafirma HD's before.

OK I'll go to the dump and see if they will weigh me. Front/rear weights may be asking too much of them... we'll see

Do you drive around, day-in-day-out, with that thing loaded like that?

It seems like you expect an overweight truck to have the same ride height as an empty one? What is the lift height when the truck is empty? I'll bet it's more than 1.5"

Yes, but I don't drive it much other than for going on trips, so it works out fine.

I don't expect the ride height of a loaded or unloaded truck to be the same... but I do expect the ride height to remain the same, when loaded all the time, over a 3-6 month period.
I haven't tried it empty in a long time, might be worth an experiment. But I can only remove approx 3-400 pounds easily

I'm confused. You said you should have 4.5" of lift, but don't expect it to be that fully loaded. But then you say it dropped 2-3" over 6 months - that would mean it was initially 3.5-4.5" lifted fully loaded??

You've got the rear of that loaded to the gills. I think you have a lot more than 3-400 pounds back there. Heck the water is a hundred.

Yes it was initially a solid 3-3.5" (with 2" spacers) lifted after installing the OMEs, fully loaded. It's dropped 2.5" since then

I totally do have more than 400 pounds. The OME's are "rated" for 450 pounds additional constant load, for 50mm of lift. I have at least double that when you factor in all the steel armor, custom swingaway, water, gear, fridge, etc. Heck the fridge alone weighs 55 pounds, and the fridge slide weighs 40 lbs. Thankfully I don't have drawers - however much I want them - impossible to justify 225 pounds for drawers.

Ideally I want a spring that is rated for my load, and to give 3" of lift WITHOUT using a spacer.... hence going the custom route. It just feels kind of wrong to have to do something custom like this... why isn't a spring available to do this? I suppose like VA_Disco was saying, there are people out there with similar loads, but they're not loaded all the time, so they can probably get away with using an OME or TF HD spring, and still get the 3" of lift. That's my theory

You may also consider is that your truck may be a thousand pounds over GVWR, and most of the excess weight is on your body mounts. I don't know how a D2 rear axle's weight rating stacks up against D1/RRC/D90, either.

Put your truck on a diet!! 45L of water AND 2 gal distilled water? Try 1 5gal jug. 1qt oil, not 4. 1qt trans fluid that works in the Trans and PS box. Nobody needs a gallon of white gas, try a quart.
I just saved you 9.5 gallons of liquid weight, lets call it 80lbs!!!

I see what you're saying about the spring rate changing, but isn't that really up to the coilsprings.com to figure out? I'll say, hey, I want a 20" spring with xx OD, xx ID, and xx spring rate - they'll figure out the rest?



Totally agree. I do what I can. For example... I dropped cast iron in favor of regular pots/pans recently, but the gains are minimal compared to my heavy hitters that I can't really downsize from - listed below. A lot of people have this same stuff so I'm kind of at a loss for why Im struggling so bad. I feel like I am 300+ pounds overweight on my current springs, at least

Over the rear axle:
  • Greg Davis bumper ~80-100 lbs
  • custom swingaway ~40 lbs
  • 45L water tank. 96 lbs
  • Alloy rack. 80 lbs (thank god I traded in the BajaRack for a Frontrunner)
  • Steel sliders. ~80 lbs?
  • Fridge/slide ~70 pounds
  • hilift
  • spare parts ~30 lbs
  • Camping gear and tools. Who knows... 100 lbs?
  • Rear seats deleted.. saves me 80 lbs
  • alloy gas tank skid ~30 lbs
  • 1 gal motor oil, 1 gal trans fluid, 2 gal distilled water, quart gear oil, gal of white gas, pint brake fluid, pint p/s fluid... etc
  • 24+ cans of beer!

I have no idea either

You're not wrong. I'm going to keep the 45L water, it's incredibly useful and I'm proud of the hot water/shower system I built. If I'm only out for a weekend i don't fill it all the way. The idea with the distilled water is obviously to have clean water to put in the cooling system if necessary, and I'd hate to put tap water in it. From rebuilding the engine firsthand, I know it's nearly impossibly to fully flush the system - and I'm super anal about that stuff. I could possibly get away with 1 gal. If a tranny soft line blows, 1 quart of trans fluid won't do me much good.
Unfortunately I burn oil (another mystery)- perhaps a quart every 500-700 miles, so I kind of need a gallon hand


My plan is to get the truck weighed, cut down 40-60 pounds of gear, put in Terrafirma HD springs w/ 2" spacers, finish the rear panhard mod, and go from there. Oh and I'm getting 315/75r16 KM3's soon Was depressed the other day when I measured my 235/85r16 K02's @ 29.5"

Haven't heard another enticing solution yet. I don't have a lot of faith in the TF springs, so if (when) they start sagging, I'll have a spare spring to send to coilsprings.com and have custom ones made

That's all I got

If you simply can't cut weight get a set of 5" RTE springs, or look into Bronco springs. There's a guy in California running Bronco springs on his D1 and getting about 5" of lift. I have no clue about spring rate, but I know they're tall.

Not aware of any 5" springs from RTE. I tried their heaviest duty springs first (but without spacers) and was sitting even lower than I am now. I also burned that bridge and prefer not to deal with them anymore. Custom made springs would also be cheaper than RTE springs

Interesting on the Bronco springs.. haven't heard anything about that... I'll try and find some info on them.

RTE doesn't make the 5" springs anymore so you'd have to find used ones.

Ditch the distilled water and carry a gallon of 50/50 mix. Why would you put water in your cooling system?

This is probably going to be a waste of money, but the Terrafirma springs arrived today.

They measure 440mm (driver side), and 425mm (passenger)
8.5 coils
18.4mm wire diameter
progressive coils

So they're a little taller and beefier than the OME's.
Annoying that they are sided springs.

If they don't work, I'll at least have a spare spring to send in to coilsprings.com

Unfortunately I won't have a chance to install them until after Thanksgiving
