Does anyone know if the rear springs on the new SRW 3500 trucks are the same measurement as the springs on my 2002 2500? If they are does anyone know where I can get a set kinda cheap? it sure would be nice to have those springs in there. I already have airbags but they just dont do enough! thanks -Jeff

man what kind of loads are you hallen

Can't you fit the springs off of a dualey ?

Can't you fit the springs off of a dualey ?





Im not sure? I just figured that the dually springs were totally different, I guess I should find that out too? Anyone know?? As far as what kinda loads am I hauling The Cmper in the Pic. is about 3500lbs. loaded. and there is about 110psi in the bags. So you can see why I need to do something...http://www.dieselplace.com/forum/uploads/wsucowboy/2004-09-30_155512_small_camptruck.JPG anyone have any other suggestions??

From what I had seen , the springs are the same thing we have now with just a little *thin* overload spring.


My sugestion is to do what JK and myself have done. Add one leaf to your current set. Add the longest leaf possible for weight and ride. I stuck one in just under my eyelet spring. They told me the leaf would give me 1,400lbs more, I think it give me about 1,000lbs. The bonus is that the ride is better, you don't get as much spring slap, the truck is raised just a bit and ya get more load capacity.


See what ya think......

Pretty sure that dualey springs would fit. Don't have a SRW so I don't know if the pads for the overloads are there or not. If the overload spring is the only difference, that spring must add a lot to the capacity.

A much simpler (and cheaper) solution is to add a leaf or two to your
existing springs. Even adding a single 3/8 inch thick base leaf in the
stack right next to the main leaf (one with eyelet bushings) would make
a big difference. I have done this more than a few times over the years.

Burner,


Your "adding a leaf" comment is interesting! Can you give me information on the leaf...where did you purchase it, a part number if available, does it effect the spring mounting bolts...


I put H2 tires on my truck and adjusted the t-bars up about 1.5". When I hook up to my 5er, the truck sits a little less than level. I believe this fix would take care of that problem.


Thanks,

I'd get that thing weighed while it's loaded (axles seperately) and make sure your not also overloading those tires.

the new SRW 3500 springs are quite a bit different. they are quite a bit thicker (something like a 10leaf pack) and they also have an overload spring on top. I have an add-a-leaf for the rear that I am going to install along with my green keys but i am pretty positive that it aint gonna cut it.... -Jeff

I am definately overloading those tires. Thats why I have a set of 10ply 35x14.50x16.5 Super Swamper SSR's in the garage waiting to go on. that should fix that problem... -Jeff

Go to a local spring shop and ask them to make and install ya a set. It shouldn't take more than an hour to drop the axel, break the spring down, install a new leaf and button it back up. ........ For some odd reason, if the shop hasn't done this on a new truck before ask them to keep it a little closer in length to the second spring. If the spring is too long... you're hangers won't be there later. http://www.dieselplace.com/forum/smileys/smiley26.gif It may be a good Idea, that and it's cheap, to replace the U-bolts or spring bolts while you're there. Although is dangerious, once you have ridden arond for a while and ridden the camper for a very short time....while it's loadedhttp://www.dieselplace.com/forum/smileys/smiley3.gif crawl under the truck and hit the u-bolts with a nice big impact.

Cowboy, I ordered another truck...... just what you were talking about --> A 3500 SRW. The truck came in... Longbed, CC, 4X4 LT.... wrong color ..inside and out! Never the less, I wnet down to take a look at it. The springs are the same with just little thin "overload" springs in there...... I'll see if I can get a picture for you.http://www.dieselplace.com/forum/smileys/smiley17.gif

All I do is go to a local spring shop where they repair springs and
have them cut be a leaf of the correct size (length and thickness) as
needed by the stack. I also get new spring packs bolts (they go thru
the center of the stack to keep leaves aligned, keep stack compressed
and to provide a stud to center in axle) as they are usually destroyed
in the process if they are rusty. I also use a big C-clamp to compress
stack to get this bolt in. (but if you contract it out you do not have
to worry about the installl part) A single leaf up against the
main leaf of 3/8 thickness on each side will increase load capacity by
about 1000lbs or more and enhance stabilty too.

The 3500 SRW trucks have another leaf in the pack.

The 3500 DRW trucks have overload springs. These require
the overload spring contact points bolted onto the frame. There
is no reason you cannot take the 3500 DRW overload setup and
put it on a 2500. You would end up with the softer ride of a
2500 with the overload capaciy of the 3500 DRW.

The parts are all there in the GM book. You can either look for a
wreck or just order new parts. This is all just wrench work, not
brain surgery.

I know how to do all that, I work at an Off-Road shop. I was just seein if I could bolt up the new springs if I happened to come by a set. Kinda like I got my green keys for free when I dropped a tahoe w/ the belltech kit and it came w/ new keys. The owner didnt want his stockers so they are all mine!!! The only thing I can think of is to do the add-a-leaf that I have and/or fab up a bracket that will drop the mounting point of my airbags down a bit.http://www.dieselplace.com/forum/uploads/wsucowboy/2004-10-01_121754_DSCN1265.JPG

Man with those spacer blocks you DO want to add more leaves to main
stack to help prevent twist up, forget the aux spring or air bags.

There is alot of incorrect information flying around in this thread. I do not know exactly how many springs are in the 3500SRW pack, but give me a month and I will http://www.dieselplace.com/forum/smileys/smiley32.gif, anyways the 3500SRW has 1 overload springs w/ the contact points bolted onto the frame just like the Dooleys. The Dooleys have 2 over springs if I remember correctly.

I have seen one on a lot here and it has one over like mentioned above
but I did not count the stack though. Beside one over will not help you
for wrapping up under load like extra leaves in the stack will.

I have NEVER had a problem with wheel hop or wrapup. And believe me I have tried!! I figure when I put the green keys on and throw in the add-a-leaf the airbags will be somewhat over-extended, so the 2 or 3 inch spacer will put them back in a position where they will actually do me some good.... -Jeff

The 3500 single wheel has one more main leaf and the over load on top.

I'd get that thing weighed while it's loaded (axles seperately) and make sure your not also overloading those tires.


I am definately overloading those tires. Thats why I have a set of 10ply 35x14.50x16.5 Super Swamper SSR's in the garage waiting to go on. that should fix that problem... -Jeff





They have a 3200# rating which is better than stock tires but the rims is what I'd ?.

Trust me, with those blocks you are getting some. Put it in 2WD with a
load in bed a put a good pull on it at a stand still (hook to a big
tree or pole) and watch those springs wrap up. THe offest for the pictured blocks will cause it.

I added springs to my chassis cab 2 main leaves and one helper

The wheels are Centerline's with a 3200lb load rating. never had a problem with them before, on any of my trucks.

Trust me, Im not getting anymore than a truck with a factory block gets. I have had trucks in the past with really bad wrapup and really bad wheelhop but this truck doesnt have it. I have installed nearly 500 lift kits on these trucks (99-05 Chevy) and have only had a couple customers complain about wheelhop or wrapup, and they always lifted more than 6". JMHO -Jeff


Did you know that some Furd SD's came with a 5" block from the factory? those trucks didnt have to much of a wrapup problem.

This will be fun to watch and learn from.

Cowboy!


Yes, the SRW springs will fit. They are exactly the same length. I work in the plant where those are built in the department that those are installed. You will need to put on the overload brackets though. If you had a LB, there would be holes there to mount them, but since you don't, you'll have to drill the holes for them. Just center the bolt pattern on the frame, and make sure that the outer edge of the bracket is even with the end of the overload leaf and you'll be set.


Good Luck with it!!!

Right on, thanks Crazydaze! I will look into it! -Jeff Edited by: wsucowboy

http://www.dieselplace.com/forum/smileys/smiley4.gifNo Problem!!!

http://www.dieselplace.com/forum/smileys/smiley2.gifWell now I got to do it to. Thanks for the help CrazyDazehttp://www.dieselplace.com/forum/smileys/smiley2.gif

Hey guys...I checked the placement of the brackets on the frame one more time. The bottom of the bracket should be about 1.5 inches above the bottom of the frame rail. Not centered like I previously posted.


I hope they work out for ya!!! I don't believe you'll have any problems!

Any price on these 3500 SRW springs from GM?



I may be interested in this swap.

I guess no ones priced it out.



Some GM parts surprise me price wise. Things you think will be
cheap are expensive, other parts you'd think would be expensive are
surprisingly cheap.

OK, I got some part numbers.


SRW Spring - 15122610


DRW Spring - 15063185


Front Overload Bracket - 15754061


Rear Overload Bracket - 15754062


You can get GM employee pricing through www.gmpartsdirect.com (http://www.gmpartsdirect.com). You can get all the parts required (minus u-bolts) for about $800.


(on edit) I got the part number for the DRW spring in case you decide you want the extra overload leaf. The only difference between the 2 springs is the SRW has one and DRW has two.Edited by: CrazyDaze
