Anyone have any offical numbers for grand wagoneer front leaf springs ?

[Greg72]

All,

Extending the excellent work provided here already, I found a number of detailed leafspring drawings and specs online for the specific Grand Wagoneer options and compiled the data into a single table to make it a bit easier to compare everything.

I added another calculation for Lbs/In using a standard formula that will help to show the amount of weight necessary to compress the leafpack by 1". This can sometimes be useful to compare different springs and get a relative sense of "softness" between them. In these examples, it certainly follows that the higher capacity springs are also the stiffest in terms of their Lbs/In ratings.

EDIT: Version 2 tables below updates specs on Rear Springs





Hope this helps.

I do believe 97-485 are 1150lbs not 1045

I think you're right. Good Catch. Will revise image as "V2" on the original post.

Please let me know if you see anything else that needs a fix, or if there is other data that should be added here.

No i noticed the 493 wasnt on there too but you added it.. Im not sure the diff between 493 and 485 though its odd.

And looking at ssprings today im noticing that Dorman is selling all these springs now. Back when i did this to my GW they didnt.

So im curious if the Dorman springs are any good, they are ALL over the place now. I know dorman is hit or miss on things, but im curious if theyre made in the usa or not. I need a new spring for the J10 rear, but i might as well get a pair for the rear... but im deff hesitant on dorman..

The springs i got for my gw dont seem to be in stock and havent for awhile. Its hard to find 485 now from stanly springs.. So i dunno if theyre making dorman ? Or whats going on. I think ill call them

Yes, the 493 seems to have identical specs to the 485 and I couldn't find the secondary part # for them but will add it to a "V3" if I do... the only reference I found was that the 493 may be been discontinued and then superseded by 485 so maybe that explains why they appear identical. I want to be careful to insure that the rear springs use the thin clamp wraps... as noted in other posts, the thick-wrap clamps can rub on the frame since there isn't much clearance on these parts.

I looked up current pricing on the springs on the 3 sites you suggested:

SDTruckSprings.com - Seem to have a good selection of these parts and good prices
GeneralSpring.com - Equally good prices and good selection
TruckSpring.com - Substantially higher prices across the board.. in some cases $50-$100 higher (per spring) than the other vendors.

I didn't try to place orders to find out if the shipping costs are wildly different. It can't be cheap to ship heavy springs.

Aren't these the Dayton springs resold by these vendors? https://www.daytonparts.com/
If so you might be able to get them locally with a break on shipping from your local truck spring and suspension service place. RockAuto used to stock Dayton springs, and they were even available on Amazon. Search online for "Dayton <above PN>" and you'll find some reference to them.

[candymancan]

Yea Dayton parts is what sold my original springs in my post.. Theyre made by stanley spring/dayton and sold by 3rd part venders. But im not sure where these new Dorman springs poping up all over are made from.

9/15 - EDIT:
I'm seeing a pretty good deal on the Dayton brand-name springs from FindItParts.com

Using Checkout Code: SELECTFALL10 They take 10% off the item costs (almost $100) and shipping is free.

I am able to get Qty 2 - 97-400 (Front 1330LB, 7-Leaf Dayton springs, and Qty 2 - 97-485 (Rear 1150Lbs, 4/1 Leaf 1150LB) delivered to my door for $893. (EDIT: Final pricing was actually $966, so really not all that impressive after all)


Tempting.

Man theyve gone up.. when i did my GW in this post it was like 600$ lol

Yep. I am scouring the various sites and really doing a deep-dive on the costs. Some places quote a low price on the springs themselves, but charge between $150-$270 for shipping. Other places offer free shipping but crank up the cost of the springs to the point where it's at parity with other shops.... but the sales tax ends up higher because that's based on the spring prices.

SDTruckspring ultimately has the lowest delivered price ($841), but it's still not clear what brand of spring I'd end up with (Chinese Dormans, or whatever).. their site seems to indicate it could be from a number of sources which makes me uneasy.

GeneralSpring(KC) is a little more expensive ($937) but at least they indicate that the springs WILL be from Dayton Parts and are sourced from either USA or Mexico but not CHINA...

I'd really like to place an order with someone, but won't until I find a source that can 100% insure a USA-only version will be shipped out.

Both those websites is where i got my springs from.. they were stanley dayton. I ordered from both because one was out offront springs. Luckily they were the same.

They also make U bilts too.. specific for what you request.. So you request longer bolts. Esepcially for the rear. If you decide you want blocks later on.. Which im glad i did.. because i put lift blocks on my 90 and didnt have to swap out u bolts

[candymancan]

I called dayton parts.. here is what they said.

The 76 Jeep J10 131 wheel base uses part number 97-459. Its a 4 pack spring. I can put 97-485 in but itll shift my axle by 3/4 of an inch back or foward i forgot which way he said.

Now the 76 J20 uses part numner 97-519 its a 9 pack leaf spring for 2400lbs load capacoty.. and that will fit my 76 J10.

But of course the ride quality will be PRETTY rough lol.

The 519 is in stock made in the usa. The 459 is a cilustom order.

He alao said they dont make the majority of there springs in the usa anymore. Its all mexico.

Dorman is also made in mexico and dayton supplies them. Ao my 76 Jeep j10 is basically fcked like 75 and under.

Something about a 76-78 J10 is different on this vehicle ? I think people have been wrong the 76-78 springs are not the same as 79+. The length is 31 3/4 inch. The 79+ is 31 inch.

Everyone keeps saying on these forums for years that 76+ is the same and its clearly not

Update i orderd 97-485 two of them on amazon from dorman. Both are made in the USA both shipped from PA.

pa is where dayton is located.. dayton said to me they have a contract with dorman. So it seems legit.. mine are usa made.

Nice!

I believe Dorman bought Dayton Spring a couple of years ago. The production of some of their stuff went to Mexico. My rear springs from Amazon were Mexico-built, but the front springs (ordered from General Spring) were still USA made.

Would have like an all USA set, but even after a call directly to Dayton it was clear that it's just not possible anymore.

ps. It was surreal ordering 100Lbs worth of springs from Amazon Prime and having them delivered in 2-days for free.

Yea i know right lol 130$ for a spring that weighs like 50lbs and free delivery in two days

[Kartboy1234]

candymancan,

Thanks for sharing the information on the springs and various suppliers. I ended up ordering from General Spring as well. Ordered set of rear springs yesterday at 3PM and were delivered this morning. I should note this was via the standard UPS (cheapest) shipping.

How have the general springs held up?

Theyre made by dayton in pa. I think ive had em on for 6-8 years i cant remember 100%. But theyre great.. 0 sag. Initially like all springs they settled down. But theyre really nice springs.

Lost no height in all these years. And the dorman (sane dayton) on ny J19 so far after about 4 months are also doing well.. ive put 2000lbs in ny j10 many times. But i do have load assist coil over shocks to help with that

Out of curiosity, I counted 8 on the front and 7 in the back, on an 86 and 85. I strongly suspect these to be oem, all tappered, the 8th is really a short skinny one on the front pad. Too much rust for a pict, but I can try latter

That's some impressive attention to detail!
