Rear Leaf Springs

[shockseals.com]

Does somebody on here work at Deaver or have a connection through Deaver?

What does a set of J40s cost? Actual price people have paid, not retail.

Is there like a chart that lists what the configuration for all these alphabet springs are?
The Deaver site shows what they fit but that don't tell me nothing spec wise...
I know, I should know, but

I've never known what all the numbers meant either. It's all too much for me.. haha!

I don't have any idea who made my springs as I ordered them through Autofab and didn't care to ask. Mine are 3" wide leaves and, if I remember right, they're around 3" of lift. The rear sits higher than the front unloaded which I like. Once all the crap is in it, the rear is still slightly higher which I think makes for better handling off-road. The last thing you want in a short wheel base truck is for the rear to run out of travel before the front which makes for some mad bucking and butt puckering. Ride on and off-road is excellent.

When i got my used f-53's, i took them in to get freshened up. Jeff asked me what type of use the truck would see, and set up the leaves accordingly. I endded up with 12 pack leaves. I have not ran them yet, but am very currious as to how they'll perform.

How much was the freshen?

Im wondering if it will be similar price to buy new shackles/hangers and a J40 pack and sell these and the shackles/hangers with chromo tig'd spacers. Probably be pretty close to even in the end and I would have something off the shelf.

I tried calling Bronco Graveyard for more on the Deavers they sell info but they didn't tell me much. I pointed out that Deaver sells leafs for 80-96 broncos in 3" and 5" lift, whereas the Deavers sold through JBG are 4", and then asked if the ones they were selling were the f53 or j40. The guy I spoke with seems to think the 4" are custom made for JBG, or maybe that's just the quickest answer he could give.

I'm also interested to know what/where folks paid for j40s...

I will hopefully be able to shed a little more light on this in a few weeks. I am going to pick up my F53's and solo shackles and hangers next week. When I called over to deaver Scott said the rates between the f53 and f64 were fairly close. He then had me call over to Bobby at Solo and explain to him what my plans were and he suggested the f53's. My bronco is a daily driver that I like to use on the weekends to chase pre run and play with a full load of tools and people. It sounds like the F53's have a bit more travel with the same spring rate. I do know that Deaver doesn't even stock the f64. Made to order only because everyone is using the F150 spring. I guess we will see.

I saw a price on the F53s recently right at 550, my J40s a coupe of years ago I scored for 350 ( Not sure on all the details as I was in a bind and my brother picked them up for me I know we got a good discount ( We had a race the following week so I think they took pity on us) My best advice is call deaver direct and ask the price and rate questions you will get the best answers for that straight form them. They are generally very easy to talk to

How many (if any) are race prepping your own springs?

I usually do, but they are reworking these and prepping in one shot. I think a race prep at deaver is tossing them in a corner and coating in ol henrys that never seems to dry no matter how long you wait to mount them.

I'm ass-uming that the "lift" numbers for the springs listed are for 80+ trucks? Aren't the 78/79's rear spring hangers different....so a 4" rear spring for an 80+ bronco comes out more like a 6" spring in a 78/79?

also assuming those are numbers w/ a stock length shackle...???
Recently built an early 90s F150 prerunner truck, and from the numbers I'm seeing, put F64's in the rear of it....as w/ a longer shackle and no blocks at the axle or anything, it wound up at maybe 2" of "lift".......not enough. Anyone got any J40's for sale?

If you really wanted to you could leaf frog the shackle hangar farther down and use a F250/350 front hanger for more lift. Usually a spring with more arch will work better though.

Anyone know what Deaver does to stock leaves to rework them?

ya, we've thought about several things. It really needs to come up.....a couple, maybe a few, inches.

truck runs real, REAL well through 1.5'-2 footers.....50-60mph.
but, anything bigger than that, and it really starts bucking bad as the rear just flat runs out of up travel, and we're just beating the hell out of the bumps.
I really like how the truck sits.....from 30' it looks like a mostly bone stock f150 on 33's. We've thought about notching out the frame in the rear and raising the bumps to get some more up travel, but, thats going to start running the springs into a negative arch, which I hear is going to really shorten the life of them. I think it really just needs a taller, and maybe even a little stiffer, rear spring.

granted, 'some' of this could be got around by stiffening up the comp valving in the rears, which we plan to do, but not all of it...it flat needs a some more 'up' in the rear.

Thats how solo sets up their rear hangers. Move the factory hanger down to the bottom holes with a bracket for the bottom of the hanger. Pics soon. I hope.

[Dust]

B.
I don't remember if you ever looked but that is the way I did my 79, had Benz build the springs.

[Berne]

well....moving the hangers down would certainly be one way to do it....but (I'll see if I can find pictures), the spring hangers on this truck are now.....well....pretty permanent. More up travel is going to come via different springs, or cut/notch the frame, maybe both. Though, if we were to start cutting frame, we'd prolly keep going and back-half the truck.

only decent pics I could find on this computer..

first....a general view of the truck to get a feel for the sleeper aspect of it.

and a couple shots of the rear of the truck....

look real close at the front spring hanger, and you can almost make out that....it isn't going anywhere...

hmmm...
I think you need springs

[Polarcub]

When I intially ran the F64 (+3") I ran into a problem with pinion angle until I reinstalled the factory wedge. I moved my spring perches finally to get rid of the factory wedge. Most people do not have an issue just make sure you keep your factory wedge if you dont want to move spring perches.

[hobbyturnedobsession]

ok that makes sense. i dropped two springs to get a little movement for now. now its a little worse. i know theres shims i can get but ive heard its better to move the perches. how do i figure pinion angle?
