Howdy All..

Besides spring rate, what's the difference between the front coil springs that come stock on the 1500, 2500 and 3500 trucks?

Is it diameter, height, wire thickness....or what? Please help!!

Wire thickness determines rate. The difference between the 1500's and the 2500's are the height and sorry I dont know for sure what the difference is but I assume it is right around 1 1/2" to 2".
Whatcha trying to do? Poor mans lift or stiffer spring?

A previous poster on Moparchat wrote that the following are the lbs load ratings
associated with the tags that Dodge puts on the Ram front springs:

The spring tags on my 1995 Club Cab 1500 2wd 5.9V8 aren't listed (#51 and #53).

Moog brand replacement springs for the Rams can be found at Carparts.com where they give different part numbers based on the engine installed and the series (1500, 2500, 3500) of the pickup.

My 1995's driver's side springs have sagged at bit. It looks to me that the Rams have an excess of weight on the driver's side ( gas tank, battery, brake booster, steering) - but I read somewhere that the centerline of the engine, trans and differential is designed over to the passenger side slightly to compensate for this.

Just some random facts on springs that I hope may be helpful.

Thanks for the responses.


That list will come in handy and interesting facts on weight distribution. Thanks.


In response to your question of what I'm trying to do...well, sorta both. The Rancho kit I had originally installed, lifted by means of spacers. I removed the spacers and replaced them and the stock coils with Skyjacker springs. These springs were JUNK!! They have developed so much sag, I've lost more than half my lift. For the fix, I'm thinking of going back to the spacers and adding slightly stiffer and a touch longer (about an inch) stock springs. Don't think I can afford custom coils being that it's the holiday season and all. What do ya think? Any ideas?

Thanks again.....Dan

I've got 20/21 combo in my reg. cab 2500 which have sagged and are too soft to start with. Would like to upgrade to stiffer springs - anybody have stock springs stiffer than 20/21 but not stiff as 38/39 (Reg. cab diesel with plow package) they want to get rid of?

The 20/21 was my original set as well. I now have them installed in my lawn tractor. And they're still a bit wimpy even for that!!

I made a couple calls to dealers today to find out if 2500 springs would fit on a 1500.
I received two different answers. One guy said yes, the other, no. So which one is it? Do they fit or not? Has anyone out there done this swap? Any problems? What springs did you change from and what did you go to?
How does it ride?

Any help would be more than appreciated....Dan
