Help re. factory leaf overloads?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Huck · 11-07-2002, 09:53 AM

Anyone have a factory leaf truck with factory leaf overloads on it. Would like to upgrade my 1/2 ton with more umphf to handle a heavier trailer and need some leaf overloads. A picture would be GREAT!! AND if someone has a set for sale and can dig them out for me and ship to KY, that would be SUPER~~~Thanks----Huck

nu2-72 · 11-07-2002, 04:52 PM

Posted this a week ago myself. Was told coils had overloads but not leafs. If you get more than one offer please let me know. Thanks.

dubie · 11-07-2002, 05:23 PM

Yeah, LMC sells auxilary leafs for a coil truck, but I don't think there is a set of leaf trucks. I plan on getting a set for my coil truck so It can haul more tonage!!!

pierce · 11-07-2002, 08:02 PM

Huck, if you have no luck I can check out Dent Springs here and see what they've got. I'm sure they have HD leaf spring helpers. Rob

*Fast68Chevy* · 11-07-2002, 10:07 PM

yes overloads wer einstalled on leaf trucks, i have a pair from a 72 leaf truck, one U bolt is bad though. i have the spacers and everything,

interested in them ?

Huck · 11-07-2002, 10:46 PM

Fast68---am interested. Please send me a description and price for part/pieces and shipping to 40003. Thanks and regards---Huckfinn45@aol.com

Rob, if the Fast68 stuff doesn't work out, I will shoot you a note and see what you know up younder. I thought I had a line on some from another member but it just didn't seem to work out.

Thanks guys as my butt is sagging (yea I know, so is my truck)!!

*Fast68Chevy* · 11-07-2002, 11:04 PM

20 for it all if you want it, G50 HD rear springs is the description of the option, the truck was a factory G70 truck

see if pic works: http://photos.yahoo.com/bc/fastr68/v...c=ph%26.view=t

http://us.f1.yahoofs.com/users/193dd...I.r89A50dW4zhg

they are packs of five leafs that sit on top of the main packs and separated by a 3/4" spacer and use same U bolts as the main packs, i have the cast iron bolt plates too that sit under the axle tubes(3" tubes)

thanks

Blue_71 · 11-08-2002, 01:16 AM

ive got G50 heavy rear leaves on my 4x4, but its just 4 leaves then a 1/2 inch thick one on the bottem of the pack?

Longhorn Man · 11-08-2002, 01:55 AM

The 70 one ton Longhorn says G60 overload springs in the glove box, and it is as randy describes.
Here is the option sheet;

And here is a poor shot of the springs through the hole where the tool box used to be. I lightened the pic quite a bit so you can actually see the spring...a little anyways.

*Fast68Chevy* · 11-08-2002, 02:00 AM

beginning to wonder if he would just be better off simply adding more leaves ot the packs, cuz if he already has HD add on packs, then....

longhornmail. on your packs what would the very ends of the longest leaf in the aux packs contact when truck is loaded down. those are the same add on packs as this truck out here had but is under different option code.

hmm...

Longhorn Man · 11-08-2002, 02:22 AM

Had to actually go out and look...
The ends of the helper spring curl downward just a pit, and they would hit the normal spring just past the 'leaf pack clamp' in front and back.

*Fast68Chevy* · 11-08-2002, 02:41 AM

normal spring as in the long top main leaf of the main pack ?

Longhorn Man · 11-08-2002, 02:46 AM

Yeah.
I'll try to get good pic in the A.M. It's just too dark right now.

Huck · 11-08-2002, 09:56 AM

As usual, you guys are great (Randy, Andy, Josh, Rob, etc.) Let me clarify what I have and what I think I need. Basically I have a stock 1/2 ton leaf sprung truck. It currently has NO add-on springs stuff in the back.
I sometimes pull a nose heavy 16' flatbed trailer that drops the truck down 2-3 inches unloaded! My Bassboat will do the same. This of course screws up the trucks handling, headlight alignment etc. When you load up the trailer, you have to back vehicles on it to have it balance which of course is a pain in the butt. AND, unless you get the tongue weight just right, you can get some ugly sway etc.
So, what I think I need is some overload spring help to minimize the drop but not ruin the unloaded ride. I prefer factory stuff so as to ensure proper design and enable parts replacement should that become a problem at some point.
So, Randy, if this is what you have and you want $20. for it all---will it take any additional parts to bolt up? Send me your address and I'll send you $$$---also advise on shipping cost or I will send you that after the fact---I do remember buying a sway bar from your collection a while back.
Can't wait to fix this butt sag!!! Thanks guys---Huck--Huckfinn45@aol.com

*Fast68Chevy* · 11-08-2002, 10:12 AM

yeah thats what i have is the aux packs just like what Andy has in pic, i dunno whats up with difference in option codes however, odd.... ill have to look that up in specs sheets later or something, whenever i can.

G50 on 1/2 ton 2wd and G60 on longhorn 2wd being same option is wierd.. hmmm.,,,,, one or th other code was not available on leaf rear trucks(when G70 was ordered), i forget which one it is though.
i wanna look all this info up first beforehand, i need refreshed on this, its been a while.

Ill email or PM later once i figure out whats up with the codes.. i gotta rig a tank on a truck for a bit first though, need ot get this truck going, need ot use it.,. havin coffee right now first real quick,

*Fast68Chevy* · 11-08-2002, 10:25 AM

i just checked it out and found out that on 1/2 tons there are two types of G50 HD rear springs that could be ordered, the first was for HD coils 2000lb each, and second type was leaf type and are single stage 1750lb each

G60 on 1/2 ton are aux cantilever style springs only for coil rear trucks

but its a little different for 3/4 tons with G70 leaves, *(IE longhorns and 4x4's)

G60 aux is equivalent to 1/2 ton G50 for leaf type rear G70

wierd,....

I'll PM you in a few, Huck

**Desert Rat** · 11-08-2002, 01:11 PM

I have them from my 69 as you know,but i havent got them dug out yet.you were waiting for a shipping price,they are a option code on my 69 GMC Sierra Custom,sorry i didnt get you a shipping price,i get busy and sidetracked.ALOT im on my 15 minute break now,by the time i get home its dark,and rarely around weekends.but im doing ONLY truck stuff this weekend,if others arent what you need ill get them out for sure.shipping might be high,i have the coil ones are also they are lying outside in a truck bed from a 1/2 ton.I have the option codes for both still on my gloveboxes.

Longhorn Man · 11-08-2002, 01:52 PM

Here you go...this is the shot that shows where the overload springs hit the normal spring pack.

And this shows the way they are supposed to be mounted in there. U bolts, spring, and the 2 or so inch spacer is all that is needed. I would recomend new U-bolts and s heavy coat of anti-seize compound on the threads.

*Fast68Chevy* · 11-08-2002, 03:14 PM

ok now i see why codes and descriptions are set up how they are, that setup ther eon that longhorn isnt same deal as whats on the 1/2 tons, the 1/2 tons HD rear leaves are actually a separate smaller pack of leaves that mount above the main pack and separated by basically same solid steel spacer as in your last pic there, and U bolts are mounted same way too, there's five leaves in the 1/2 ton version versus the single thick one on the longhorn,

the 1 ton duallies HD mains and aux 4150lb packs setups are pretty similar to this half ton version such as what i pulled off this 71 or 72 or whatever you wanna call it.

pierce · 11-08-2002, 05:30 PM

Andy...that camera takes awesome pics!
I should add those on mine cause it squats like a woman when I put weight in the bed.

OLDCHEV4X4 · 11-08-2002, 06:01 PM

Andy, I thought the aux spring had its own set of bumpers to hit that was mounted on the frame. Its been a while....Maby i'm thinkin of something elese.
Randy

*Fast68Chevy* · 11-08-2002, 07:04 PM

yeah thats whats odd about it, Andys are called aux and the oens i pulle doff are called HD and they have the bumper deals on the ends of the longest leaf

Longhorn Man · 11-08-2002, 09:28 PM

Rob, I'm suprised you can get a one ton to squat at all...I wonder if someone has swapped out your springs, or removed a leaf. It is fairly common to have a leaf or two cracked...this one ton is the first leaf truck I have seen (of few that I have seen in person) that has solid springs.
Fast... This may be modified, but being that the description is differant, and the fact that I have no reason to think it was messed with...I'll consider it original. It only has 130K on the clock.
OldChev...You may be thinking of the set up that Fast is talking about....I automaticly pictured the 1/2 ton coil helper spring/overload...what ever, but I guess you've seen something I am unfamiar with.

OLDCHEV4X4 · 11-08-2002, 09:43 PM

Andy..in the last pics you posted, the top pic, it showes the top single aux leaf. What is the bracket that is riveted to the frame behind the end of the leaf?

Longhorn Man · 11-08-2002, 09:57 PM

Hmmm, I'll have to go out and look. BRB (like this is a chat room or something)
