Planning ahead for 3/4T 4WD Suburban suspension

Those 2" front lift springs, ORD or Tough Country will give amazing droop travel if you run a ford shock mount and longer shocks, and remove or quick disconnect sway bar. However without cross over steering if you droop the drivers wheel you can't really turn left. The less arch a spring has the better it works, and flexes.

I've heard the difference between the Tuff Country EZ ride springs and the HD springs is they put an extra leaf on the bottom of the HD pack. If it rides too stiff you can remove that bottom leaf. I don't know what the difference in cost between the springs is.

I was running 285/75R16s with what was actually a 3" lift.

Here is some of the articulation with the longer front shocks on the HD springs:

You're absolutely correct, yes you can ditch the bottom spring and end up with a standard Tuff **** spring.

I think most will agree... I've always deleted them. I find they get rusted and don't work, yet the brakes still stop the truck so off with it.
Does your rig have a tach?
4.10s with stock 31" tires would be so revy on the highway. I don't think Eric is correct about 4.10s being standard on 3/4 tons. I have an 85 K20 Camper Special with 3.73s. I've had a few and they all had 3.73... even the Camper Specials. Now moving up to one ton camper special or CAC dually and they all came with 4.10.
But... as we see over and over, it seems any and every option may end up where we're not expecting it.

I don't know how accurate this is- but I've went by this chart for lack of any better information.

It's hard for me to see it clearly, but pre '81 K20s with 4.10s makes sense in my memory hole. Thanks

Well guys, I stand corrected. Checked the code, GT4 just like I remembered, which means 4.10, right? Wrong. 3.73's it is.

I had it in ming that GT3 was 3.73 and GT4 was 4.10, but GT4 is 3.73 and GT5 is 4.10. Guess that's what I get for thinking instead of looking...

Side note, if anyone is wondering if their truck is still under warranty, I've got that manual in the glove box.
