I saw these leaf springs at a JY near by but I'm not sure what size lift they are for I know they are not stock cuz they do look different. This is the part number they have on them
RPN2390 1024 I tried to google the number but nothing came up. You guys know where I can find info on these

 

These are the leaf springs I'm still not sure what size they are or if they're even stock but they're in way better shape than mine

This is all thats on them But I couldn't find anything on google.

 

I googled the part number and all I found was this thread. What irony.

 

how many leafs are in the pack if theres 4 its probably stock just in good shape if theres five maybe the pn is the pn for an aal they look pretty stock tho

 

I tried it on google with different combinations like RPN2390, and RPN 2390. but i didnt get anything relevant. I also tried it on thesuspensionking.com, quadratec.com, and jcwhitney.com and got nothing.

I realized PN in the code probably stands for part number, so i tried just R2390 1024 and R2390 but with no luck.

 

yeah i fig'd they were factory and the RPN stood for replacement part number???

 

That makes sense. I'll have to call a jeep dealer and find out

 

You'll find that factory springs where offered in there different rates. Stock, Heavy duty, Off road (Up-country pkg.) And their arches are different: Stock has a 4" arch, Heavy duty has a 5" arch, Off road has 6.5" arch, and will give you 2" of lift. But they recommend different shock travel length ( Used in the factory Up-country pkg.) If you goggle Mopar-Jeep Parts catalog (for your year). you can find it in PDF format. To down load. I only have it in 1988-1993. But that's what I did.
