The 92 W250 SRW, cc, CTD I just bought (for reasons unknown ) has blocks between the rear and the springs that are 5" high. They do look like they have been there forever. the guy I got it from ,bought the truck new and SAYS he ordered a one ton, the truck says 250 on it?? . it sits real high though even with stock tires. HE said it has always been that way.
there are numbers on the sticker under the hood that says it has the 4500# front axle, in another spot it says 2105/2500 PAD/GROUND FR and 3250/3650 PAD/GROUND RR. which is obviously front and rear ratings for something. what does pad/ground mean???
he did buy it new according to the title , but he also said he ordered it with 4.10's and the sticker says 3.5 and i did verify that the hood is original to THIS truck.
guess I want to know if this is 350 SRW ? and would it have the same D60 front D70 rear as all others??
the guy told me it was rough, but this is a junk parts truck only

 

Those are factory lift blocks in the rear. All the later (91.5-up) 'w' series trucks sat pretty high. Can't help with the 'pad' thing, sorry. All Cummins powered first gens had the Dana 60/70 combo, regardless of 250/350 or srw/drw. The autos did have a lower spline count on the tranny-to-transfer case coupler, though.

 

shes a get RAG! like to know about those numbers anyone, thanx for the help so far. crossy

 

The only diff in the 250 and 350 is a sticker and how bad the the ticket will be if the D.O.T. catches you over loaded. I have a 350 SRW 4x4 and 2 of my friends have 250 4x4 and they are exactly the same. I have a 2WD 350 that has over load springs but that was an option.

 

So did they not put the Dana 80 in the rear 1 tons until 94? As far as I know the only is in the shackle bolt size the 250's are 5/8" and the 1 tons ae 3/4". I doubt that would really come into play though as far as hauling is concerned.

 

I'm not concerned at all with towability and weight ratings so much as understanding what these sticker numbers mean. I also wanted to know if 350 SRW trucks were marked as such? persinally since i am fairly new to this I can honestly say that I have never seen a 350 at all. A guy I work with has an 86 NON CTD 350 dually but he all the emblems removed a long time ago and he can't remember what it said on it. I have definitely never seen a 350 SRW first gen. One of my other questions was already answered , I think, About whether certain weight models had larger rears like the Dana80.
I mean the guy had nothing to loose by telling me that he ordered the truck as a 1 ton. I'll eventually open the rear to CHECK what ratio it really is. I know, unless dealer installed, that the underhood sticker is probably right in that it has 3.5 rears. It also says limited slip and the guy swears that all four tires spin in a jam. Did they actually put L/S in the front Diffs???

 

It SHOULD have 350 badges, but it wouldn't surprise me if it didn't. I've seen a '98 12 valve with factory "24 valve" fender badges.

I have a dealer sales manual for '93 that gives the spring ratings for our trucks.

Up front all diesel 4X4's should have 4,210/5,000 lb springs.
In the rear it should have either 6,500/7,300 or 6,800/7,600 depending on whether it has the 7 leaf or the back-breaker 10 leaf packs.

The stickers are rating the springs individually where the book rates them as a pair. So you have standard springs front and rear.

BTW, pad ratings are ground ratings minus the unsprung weight. Pad ratings are the "real" rating.

 

I've owned 2 W350 SRW's, a 91 and a 93. Both were ordered that way, I bought them both from a landscaping company. The GVW was 8700#, on W250's its 8510#. The sticker on my 93 said 5000# front axle, but every 250 I've ever owned(3) says 4500#, they are both dana 60's. The 350 had more springs in the front than a standard 250, I have the optional springs front and rear in one of my current 250's. Rear brakes according to the sticker were both 2.5" wide also. Its a total mystery to me what the difference is, I posted a thread on the other forum and no one knew either. They also both came w/ "Power Ram 350" emblems, and the titles both said W300.

 

boy that really clear things up huh, LOL I guess it is just a plain ole 250
the guy got snowed by a salesman- imagine that.

Dave, it does have 7 in the back and 6 in the front pack. might as well have STRUTS for the way it rides. thanx guys

 

SHould have smaller brake cylinders in the back too.

 

Now I'm real confused. My truck is a 250 but the rear brakes are 3" wide like the one tons. That must've been an option then I guess? The badges said 250 on the side and the sticker says gvwr 8510#. Front axle is 4060# and rear is 6084#. My truck is a 91.5 .

 

It may be an SRW W350. The only difference between an SRW W350 and a W250 is rear brakes. Spring and axle ratings are the same, and there's only a 190 lb. difference in the GVWR. The differences are much more pronounced on gassers. A W250 gasser would have lighter front springs and a D60 rear, so moving up to the W350 would make a bigger difference.

 

hey Wanna, does this mean I can turn my 250 into a duallie?

 

Again, weird cause i just found a W350 gasser for sale on an off roader website, Now those guys are into rears,(The metal kind!)
, his gasser 350 has D60 on both ends. I guess only the CTD got the D70.

 

Both of my SRW W350's had 12x2.5 rear brakes as factory equipment, per the sticker under the hood.
