Front coil springs
I am thinking of replacing the front springs on my 32.5 anyone know the weight rating. I can't weigh it as I have it up on jack's at the present time.
The brochure I have says 2500lbs each for a gross of 5000lbs dose this sound right or should I go a little heaver

If that is a GM chassis you should be able to read the as built codes, commonly placed inside the clove box. Not sure Airstream would have put them there. Then see if a dealer will give you that information from the vin number.
Another possibility would be contact a truck spring shop. They should have a way of tracking the info down and a good place to get the springs.

Your VIN full decode should give you the rating. My 250 classic reads as follows
AXLE,FRONT(5000 LB) 5000 POUND F/AXL(YC4)

Front springs
Hey,
When I took my front end apart, I put new coils in . I decided to go with the heavier springs. I can't remember , but there are two weight capacity springs available. My reason for the heavier cap. Springs was to lose the airbags . Those airbags purpose was to give you a little more gross weight on the nose. I think these units have a tendency to dive a little on the nose. The p30 cub vans had those little airbags in the front coils. They had a tendency to propose a little.. Seems to me, the weight capacity for the heavier springs was 7000 pounds . I think. I don t think it ll be to stiff. We ll see, hope this helps a little. DJ

I installed the super steer coil springs and bell cranks on the front of the 345. I eliminated the airbags as well. Much improved driving and the dip is very much improved. New shocks helped tremendously as well.

To be clear to anyone responding, John has the turbo diesel Isuzu engine that weighs 400 lbs more than a 454, and the 545 Allison which also weighs more than a GM 475. That has to play a part in the calculations I'd imagine.
Cheers
Tony

John, the original part number for your front coil springs is 14054345, being that Airstream did the diesel conversion I doubt they put heavy duty springs in it. The stock replacement spring part number is now 88913432 rated at 3289 lbs. The heavy duty replacement I believe you need is 88913524 rated at 3789 lbs. although this would raise my 325 LE up 3/8" to 3/4" I don't believe it will raise yours up any more than 1/2" because of the diesel/Allison additional weight. In any case I would still use the air bags inside the springs for a nicer ride. Regards, Bob

Thanks for the info Bob are those gm numbers or parts house.
Did you use the heavy ones in your 32.5 I'm wondering if they might be a bit stiff at 7500lbs for the 2 springs.
I haven't checked on the weight difference yet probably around 500 lbs

I think I am right in saying that Henderson can supply springs to meet varying weight requirements.

John, those numbers are AC Delco factory numbers....Rock Auto or E-Bay is a good source for them...I would take your 325 and weigh the front end...I'm sure you know where to get that done !!! LOL. Also if it were me I would go for the HD springs, new front air bags, they're only $100.00 or so, and it's a great time to change them, and the only way as far as I am concerned. Also while doing this job if you have not done the ball joints now is the time do do them....remember not to use an impact gun tightening up the new ball joints because of the tapered seat, hand wrench only. Regards, Bob

I just put new air bags in 2 years ago and at that time the ball joints were good.But I will check them again .I know what you mean on the ball joint stud.
I checked last night and it looks like about 600 lbs different between the 454 with the 475 and the Isuzu with the allison 545

Can you tell me what your front axle weight is. I have the same MO and need front springs.
Thanks Hans
