Rear End Sag Fix?

[Fix4Dirt]

they seem good!!! i like poly ones just for durability, but offroad rubber is probably better!!! smoothness=rubber, durability=poly... speaking of which i need to get me some extended bump stops someday!

New Dayton leaf springs lost 75% of arch after install...see pics

Hello all. Last week a local garage installed a brand new pair of Dayton leaf springs. Dayton pn 43-1159, direct replacement for F57Z-5560-A and B. Springs were purchased online, not from the garage. The springs are now flat from front spring bolt to rear axle. There's some, but not a lot...

I just looked at that post and that's damn near what my springs did, they look almost completely flat

dang! thats odd! my OMEs dont do that! obviously they arent super ached in the center, but they aint makin a W either!

Guess I'll order the Timbrens and then take a look at my springs to see how flat they really are, maybe my mind is tricking me

what brand did tou get for the springs?

The shop did that part so I'm not 100% sure

It’s possible the shop used the wrong leaf springs
A longer shackle can gain you an 1” or so of lift to help level the truck

I have seen a lot of people run the shocks with the helper springs on them to help with the rear sag and help carry the load
I think Monroe makes these? I see them on explorers all the time

There are 2-3 different spring rates for the back of an explorer, if the shop chose a spring too soft then you will need another sort of helper spring to get the ride height back… helper springs are
Add a leaf
Air bags
Shock/struts with helper spring

Or you could make a hybrid leaf pack by taking your new springs apart and adding more leads or different main spring (like f150) sucks when you have to pay a shop to do the work.

Did you take your truck back to them and ask them why it’s low in the back with the new springs? Of your new leads have already de arched then you may consider trying to get stiffer ones from the same shop, maybe they will warranty their work?

What you’re describing is why AAL exist. Install AAL and be done.

 

[Mbrooks420]

I’d try for a warranty claim, and a heavier set of springs. At the very least they should be able to rework your pack to improve it.

Barring that, I’ve only known of satisfied customers who purchased springs from Old Man Emu.

AAL is bandaid imo since other springgs have lost arch. also the short AAL rides bad imo. long AAL not so bad though, but it also increases the thickness of the spring pack on an SUA vehicle,m. if its a street vehicle not too bad, but for offroading you want more clearence there. but jmo

as someone with OMEs I can say im impressed!!!!! they flex well and are well built imo.

Ever since we put the new rear axle in the leaf springs have been fairly alright, it'll sag with weight in the back if you let it sit for too long but driving down the road it doesn't for some reason. I'm planning to order some EMU springs like dirt said, once I'm done throwing money at other parts first.

With my 87 ranger, I cut the eyes off the ranger main leaf then laced the leafs into an explorer pack. It gave me a little lift in the rear, and doesn't sag when I put something in the bed.

Well yeah. If the stock springs have lost arch, then get them re-arched and then AAL for your increased cap.

If I went through the trouble of removing them, I’d replace them with something better that doesn’t need a band aid like an AAL.

How many companies have the equipment and know how to re-arched springs by the cold setting process and how much does it cost to do it properly by the heat-treating them?????

The "Add a Leafs" are very stiff, thicker, and you loose the thickness of the added leaf in ride height because the leaf pack is under the axle.

Even if the add a leaf is the same thickness as the other leaves in the pack, maybe a cheap junk yard find, you are adding another leaf to a small, short, pack, and increasing spring rate by a large amount.

I don’t know but I had my springs re-arched 5-6 years ago and added an AAL for capacity and they’ve got easily 75k on them now and are not sagging a bit. Still have all the lift they did when they were re-arched. I believe I paid $100 to have them both re-arched, including the AAL. The shop just used the cold process with a press. Worked perfectly.

The original question was about adding capacity. That’s what AAL does.

Who cares about losing 1/4” ride height with adding AAL? your usually gonna add taller tires anyway. If you don’t, your talking 1/5-3/8”.

Mbrooks420, AAL isn’t a bandaid. They’re made exactly for adding capacity. If you want extra capacity, that’s an easy way to add it. Much more affordable than custom springs and you get the same result,

They are made to add capacity as cheaply as possible. A taller set of springs would do everything better than an AAL.

Taller springs don’t add capacity, but if you want to spend extra money over an AAL and a re-arch to accomplish the same thing, it’s your money.

I’m aware of how springs work. They are not equal. An AAL is the same thing the way welding the spiders and lockers are the same.
