? Will 2500 springs mount on a 1500

roland13 · 04-22-2007, 07:38 PM

Ok
New to the forum and have a couple of questions, I have a 1992 Silverado extended cab, 4X4, Auto. And I have a 1400 pound camper, Well the rear springs are sagging pretty good. Can I replace the springs with the same year 2500 rear springs? Or should I really be looking for a true 3/4 ton truck?

Thanks for any help

welcome roland13 to the site. There are lots of opinions here and share one of them. You can upgrade your springs but is the rest of your truck capable of that type of weight? I have a 2500 and when I tow my 5th wheel (1100lbs pin weight, 9600lbs dry weight) my springs sag. The only difference is my brakes, trany cooler, etc. help the rest of the towing weight. You gotta remember once you get it going down the road at some point you're going to want to stop. Depending on legislation in your state you may not be able to carry that much weight anyway.
You may want to try air bags as an alternative anyway, they're about the same price and when you don't have the load you can release some presssure and still enjoy the Chevy ride.

No they will not I don't believe. 3/4 tons used longer rear springs. The best way to tell would be to measure the springs and see if they will match.

I think they will fit. If I remember correctly all of them are 63, or 64 inches long, and only 2.5 inches wide. The 2500 uses a thicker spring pack, so new u-bolts will be required.
I agree with ryeja. The point of over tasking the truck is a wise one. That is a bunch of weight, and the drivetrain will be burdoned. The brakes will have to work overtime, as will the smaller transmisssion, and rear axle.
I like the airbag idea, so when you are driving empty you can easily deflate the bags, and maintain a better ride. For the time, and money you will spend on buying new springs, and hardware, you will probably be ahead of the game with the bags.

Thanks for the quick replies. I think I may do airbags for the time being and keep my eye out for a 3/4 ton or 1 ton truck.

Thanks again

I have to agree with the general opinions here. my own truck has a few extra leafs in the rear. while it does handle a heavy load, the brakes are clearly inadequate. I even have the HD brake option, can't remeber the rpo code off hand. only difference is the calipers have a larger bore/piston. the drums are the small ones, although I suspect the wheel cylinders have a larger bore/piston as well. The brakes heat up quick, and really lack in overall stopping power. my brake componets are in A1 shape too. recently did a complete overhaul, everything was replaced. I'm very **** about my brake jobs too. The truck gets pushed pretty good when I tow a car trailer. I wouldn't consider going any long distance with out trailer brakes. another thing to consider is the rear end. While a decent unit, the 8.5" is not a floater, and the axles will be under consderable stress with the extra 1400 lbs hanging over, not to mention all the **** involved in camping. they will probably be pushed to there limit. I guess what I'm getting at is there is alot more to a 3/4 ton truck than just the springs...

Well one ton springs fit, raised the back of the truck 1.5". Now when the camper is in there, the truck rides level. My old driver side spring was broken, That would explain the extreme sagging. I looked at a few trucks down at the wreckers, a couple of the 3/4 tons had the same rear axle housing and brakes as mine? I thought all of the Chevy 2500 and 3500 had the bigger 8 lug axles. Stops and accelerates great, no problems so far.

they chould of had an 8 lug.

What is the weight difference between a 1500 and a 2500?

I'd be reluctant to swap them out unless the 2500 springs are a direct heavy duty substitute for the 1500 springs.
