Question

Well this question has probably been asked to death, but here goes. So what happens when you put wagon springs in a sedan. I have checked the Moog catalog specs and it looks like the wagon has stiffer spring rates and about a 1/2" drop.
Sedan front 336 lbs/in @ 11" rear 129 lbs/in @ 9"
wagon front 449 lbs/in @ 10" rear 156 lbs/in @ 8.5"
I might be off a bit as I don't have my catalog in front of me but I'm close. My goal is to just stiffen the springs a bit without any lowering or not much. Any ideas?

Please don't post the same topic in multiple forums. It creates clutter and makes it hard for people to keep track of which version of the thread they posted advice in.

This thread, for example, would belong better here in the Suspension forum than the Caprice forum.

I have used the wagon "RX" springs on my Impala. If I remember correctly, the "RX" springs are the stiffest. The do anything but lower the car! They are as stiff as my ST's but they must have raised the rear by atleast 2 inches! I used them with the 9C1 front springs -1/2 coil. Very raked look and handled very well. I can not tell you about any other wagon springs. Hope this helps a little.

BBHP#13,
Thanks man, I appreciate the response. Others have told me that these springs (wagon) are way to stiff in the rear and would raise it up. Since I have to keep the boss happy a harsh ride is out of the question. I am awaiting my MOOG Coil Spring catalog to arrive in the mail, I am hoping that I will be able to mix and match a set from this info. Also, there is another Caprice owner who is researching so between the two of us, and with help from guys like you, we will come with a good combo. Thanks again.

FWIW, the stock front springs in my '92 Roadmaster wagon are identical to the stock front springs from my '96 SS.

The '91-up wagon rear springs will raise up the back of a sedan B-body a bit too much, at least for my tastes (although you've got a Caprice, right? - that might make things a bit different). I run the '90 wagon springs in the back of my SS and it raises it about 1/2", and doesn't sag with a full gas tank and trunk.

Thumbs up

It took me a half hour to find the right place for the catlog, but I got it and here is the address:
http://www.federal-mogul.com/fmeconnect/productservices/product_service s_contact_list.asp?flag=Category

This should put you right at the place to select the type of catlog you want. Note: I used a business address. I don't think they sell direct. Anyway, in the comments section make sure you tell them you want the COIL SPRING catalog for late model Chevy Caprice WITH the update. The chasis components like ball joints and bushings is another catalog. So tell them exactly what you want and good luck.

FWIW, When I moved to the Chicago area I drove my car up loaded with the stuff the movers wouldn't take and the stuff I wouldn't let them take. This was just too much of a load for my ST's. The car was bottomed out way before it was fully loaded! Since I had the RX springs in the garage, I swapped them out. Rears only. It put the car right back at the height it was, unloaded, with the ST's. Heaven only knows how much weight I had in the car but it rode very nicely from Jacksonville to Chicago. Now, when I unloaded it [img]4.gif[/img] ! I have no idea how high the back really was, but with the ST's on the front and the RX's on the rear...serious nose dive . It was kinda fun to drive like that for a day or two just to see peoples faces. Anyway, I thought it was funny.
