The difference between the F67 and H70 is 2-2.5” inches of free arch. I got them direct from Deaver. They told me the H70HD was more of an “overland” pack than a race pack. They made it to carry more weight, since lots of guys are building mini RV’s out of their Tacoma’s now.How much different are the h70’s to the f67’s? I was talked into the h70’s then giant only was able to get the h70hd’s but marked some leafs to remove that made them hd’s. Also I didn’t want any more lift but dang so far it sits quite high with them. With no weight they ride stiff but are brand new and my 200lbs barely makes them wiggle.
I semi used the magic number for locating the upper shackle mount on the 12” shackle but also did the 90 degrees at full droop. I even loosened the bolts so they weren’t impact tight on the springs and shackles. The bed is empty and I don’t have the bumper, bed rack or spares in the bed yet making it stiff as a brick. They’re also a lot higher but they marked a leaf I can pull out to reduce the lift like the leafs that make them hd’sThe difference between the F67 and H70 is 2-2.5” inches of free arch.

My truck is a little butt high when empty, but once I add the double spare and gear to the storage rack, it sits perfect. It works awesome and keeps up pretty good with linked trucks on mild to moderate terrain. When the holes get too big, I can’t keep up anymore.
Shackle angle can play a big part on how the springs work too. Also make sure nothing is biding.
Sounds like you have a couple of things that could be the issue (or a combo of them).I semi used the magic number for locating the upper shackle mount on the 12” shackle but also did the 90 degrees at full droop.

The last part gave me a good laugh. Yeah I’m sure I’ve done something wrong with the set up and think I’m like 1/2” from the magic number. I ordered the h70’s but giant gave me the hd’s and told me the bottom 3 leafs can be removed which I did. I don’t carry my tent all the time And now I guess I’m going to try and make a really heavy bumper. I kinda wish I went with the f55’s now since I didn’t really want to lift the truck and only run skinny 33’sSounds like you have a couple of things that could be the issue (or a combo of them).
The "magic number" is supposed to apply to all 62" springs (f67/h70/etc) with a 12" shackle. I have the f67 pack on my p/u but didnt use the magic number when I set it up... no amount of weight will make this truck ride "great". Loaded for a weekend of camping gear, with a spare tire AND a RTT = ok-ish ride quality. Ive revalved the shocks and its made a slight difference, but in the end I know what the problem is - the idiot that set it up didnt do it right (thats me btw). Ive added hundreds of lbs to the bed in an effort to figure out what the problem is, and no matter what I do, the rear end never feels "soft".
I also have a 1st gen 4runner with what is essentially now an H70HD pack, and that truck rides GREAT. Nice and soft/compliant, boogies in the dirt and very comfortable. Doesnt squat until Ive added 3 200+ lb dudes and all of their shit for 4+ days in mexico, plus a giant cooler for the trip. No complaints with the HD pack. Keep in mind Ive got the factory hard top, a cage, full size spare, 100lbs in tools/parts/etc, all riding at or behind the rear axle.
If I were you, I'd add your weight (or what you think your stuff will weigh) to the ass of the truck and put a few hundred 'real world' dirt miles on it and try to get the pack to "break-in" (or 'settle', whatever you want to call it). If after that its still riding like a dump truck, Id move the shackle pivot to the "magic number" and try it all again. If after that youre still not happy, Id back and front half the truck, then sell the incomplete project for pennies on the dollar...
Honestly, it sounds like you did the same thing I did (incorrect initial setup). 1/2" makes a big difference, or at least thats what the ladies say... I ran F55s for a while but the truck squatted too bad, it sat really low. I switched to the F67s and at least now it sits level... still rides like a brick though. For shits and grins I'd strap 300lbs of (???) behind the axle and cruise around, see if that fixes your problem. My guess is that it wont, but its the cheaper and quicker "test" that you can do today to rule out the springs as the problem.The last part gave me a good laugh.
