You'll want to look at the S-10 rear springs. Part # UCF America 22-687-ME is the 1350# load spring. This is the same load rating as OEM, but arched higher (so "lift only"). For most people this is the correct set of springs.

There is another part# 22-687HD which is the "Heavy Duty" load rating (1750#). Those will likely ride very harshly unless you actually need the extra 400lbs load rating (i.e. you routinely run very heavy in the rear). Note that if you're running 1750# springs and a matching heavy load, you'll probably need more damping too, so look to replacing your shocks.

Do you just want lift, or do you really need the HD springs?

I love my S-10 leafs! BIG change in ride over mushy stock. Quite firm not quite harsh. truck-like. Loaded 1000lbs of mulch BEHIND the rear seat with no issues.

Thank you for information guys.
I just added new leafs from a donar Astro, which had 3+1's . Assuming these are oem leafs, forgot to look at rpo codes yesterday. Loving the ride so far, didn't change shocks yet. What would you suggest for shocks, and yes I'd like to achieve a little xtra lift if at all possible.

Seems a little silly that you came here asking about "interchangeable HD leafs" that would give you lift as well... you got a great and very informative answer with several options (complete with rating specs and part numbers) ... and then you went and installed basically the same stock Astro springs! Now you reply back that you are STILL looking for "xtra lift"... "if at all possible". Well, I think you know it certainly IS possible... and S-10 springs would have nicely accomplished both your initial requests.

I would assume if you're going to run 31" tires, you are going to need better than factory "stock".

Like the other reply posters, I am also running the S-10 springs.. and they work perfectly!

For more lift (without using suggested heavier HD S-10 springs which fit perfectly)... there's always shackles and blocks. (both also work satisfactorily for lift only)

Good luck.

There's no lift to be had from shocks - they're dampers only. Lift will come from the springs, or from changing shackles, or lift blocks. There are a lot of options. For the price, a set of junkyard S-10 springs is your best bet.

The Astro and S-10 springs are both 3+1s and the same rating, just that the S-10 springs have more arch.

And once you have achieved your desired height, you will need to change your shocks as has been mentioned to a longer unit or stay with the stock length and modify the lower mounts to raise the lower shock eye up 2". It's on line

Just installed the 1350 # Leaf Springs(Michigan Truck Springs)....raised up the rear around 6" ( I carry a lot of tools) I'm very happy

that I did not go the 1700# route..Might need to raise the front a couple of inches now so that I can see Stoplights changing.

The springs will settle some eventually.

If you actually need increased load capacity and not as much lift then Astro 22-1195HD springs would be an option. #1700 load capacity and not as much arch as S10 springs.

I like the lift, just put My 60 gallon air compressor on the Hitch Basket/hauler and it weighs around 200 lbs...not a problem

Thanks for the clue on multileaves for the rear end. UCF America P/N 22-687-ME is almost a shortlist for the 9" full-float when I place the order to Currie Enterprises, Inc., in south State; I also plan on disc/drum upgrade brakes but need to ascertain the correct dimensions of rotor, should I stay with the 5-on-5" lug pattern and 15" rims. (Full-float is a lot easier with 6-on-5-1/2" due to better clearance for both the full-float hubs and the parking leading/trailings; Ford Motor Company should have appropriate 6-on-5-1/2" disc/drum rotors from certain years of E-150, F-150 and Expedition.)
