Crash Posted October 21, 2015 Share Posted October 21, 2015 Found these on JCW in some searching for rear leafs. http://www.jcwhitney.com/crown-automotive-jeep-leaf-springs/p2005969.jcwx?filterid=d1169y1988g2j1 Any body know if these are correct for an MJ? I know that people will say, "you get what you pay for" and "go with something better quality", etc. If I had the money money for Hell Creek leafs, I would do that. But I do not. Hopefully picking up an additional set of MJ leafs to "build my own" set. But if these crown ones are legit, I'd consider buying a set. Amazon has them for cheaper than JCW, so I will most likely go that route if I do end up buying a set. Also, saw that Rusty's makes a set of 4" lift MJ leafs. From what I gather Other than their Coil springs, their quality/CS isn't great. Seems like a reasonable deal if they are solid though. Constructive criticism and comments are welcome. Thanks in advance. Link to comment Share on other sites More sharing options...
Eagle Posted October 21, 2015 Share Posted October 21, 2015 Your link shows me front springs. Those would be for a CJ, or a YJ Wrangler, not for an MJ. In general, Crown makes good stuff (my Jeep dealer sells Crown parts and I've used a lot of them -- but no leaf springs), but their parts are vehicle specific. Most Crown parts actually use Jeep part numbers, so you should be able to select that way. However, JC Whitney probably won't show you the Crown/Jeep part number. I can't recommend Rusty's springs. Save your money. Are you looking for new, stock height springs, or for a lift? Correction: They do show the Jeep (Crown) part numbers. Link to comment Share on other sites More sharing options...
75sv1 Posted October 21, 2015 Share Posted October 21, 2015 From what I read, the JCW are for 'each'. So double the amount. Maybe I am wrong. I looked at Hellscreek for the MJ. I bought a set years ago. I haven't installed them yet. But I looked at the website $229 (?). I did get a set for one of my Xjs last year. 4-1/2, they were made in China. They were arched for probably 6 inches. They never settled. Actually, that is a sign of a well made spring, to my understanding (Tune to Win, Carol Smith ref). They are Rough Countries.

Crash Posted October 21, 2015 Author Share Posted October 21, 2015 I would like some lift. My truck is 2wd, so I figured hd or metric ton leafs would net a couple inches. Hell creek springs would be nice, but not in my budget. I figured that if crown replacement leafs are legit. And add a slightly longer shackle, it would be an inexpensive way to freshen up the rear. On the JCW site when I input jeep comanche info the 3 different numbers popped up. The ones that I believe are metric ton replacement are 98 each with free ship on amazon. I do have a full set of JKU Rubi shocks that should work for now. Link to comment Share on other sites More sharing options...

Crash Posted October 22, 2015 Author Share Posted October 22, 2015 Oh well, I guess I'll be making a bastard pack soon after I get my spare set of MJ leafs. Thank you all for your help. Link to comment Share on other sites More sharing options...

chopper35nj Posted October 23, 2015 Share Posted October 23, 2015 Both a buddy and I went round and round with rear springs and here is what we found the best solution to be....(I wish I had done this) He bought a set of F150 springs from the JY and we re drilled the shackle pocket 1 inch back and opened up the holes in the front pocket to fit the Ford bolt (much larger, and, defiantly get that bolt with the springs at the JY, they are expensive and hard to find $64 ea from Ford) we just used a step bit, super easy. Used 3/8 Allen heads to replace and flip the pins (the Allen heads fit better than stock pins, no grinding necessary) Bolted in like stock. Gave 3 inch lift and rides better that it ever has. Next time on mine I'll be doing this, Ford springs lock, stalk and barrel.. Oops....forgot to mention a few things, Use the ford shackles too, they are almost identical to MJ shackles and the springs were $85 for the set at the JY, SUPER cheep.

chopper35nj Posted October 25, 2015 Share Posted October 25, 2015 1997-2003 58" leaf packs. My buddy Mike found a set of 3/1 leafs. The newer Ford springs "seem" to be a superior spring compared to anything else that I found and are progressive. Link to comment Share on other sites More sharing options...

1stDeuce Posted October 26, 2015 Share Posted October 26, 2015 I don's see how ford springs can work unless you're spring over... I wouldn't think they have nearly as much arch as the comanche springs need when mounted spring-under. ?? Both General Spring and SD Truck Springs sell replacements for Comanche, in normal (3+1 leaf) and Meteric Tonne (3+2 leaf) versions. They are not cheap, but I found a reference a while ago on another site that suggested they were quality units. FWIW, I'm a firm believer in adding one full length leaf to the pack as a great way to boost the carrying capacity and add a little lift w/o making the pack too stiff. Any competent spring shop can make you a pair of leaves based on easy measurements for reasonably low cost. (Like under $100...) I do NOT recommend using short "add-a-leaf" type kits intended to raise the ride height, as they generally kill a spring pack by concentrating load where it's not wanted, and they seem to always ride like crap unless you're really loaded. Full length add-a-leaf kits are better, but not many out there... Long and short kits all rely on using an extra thick, over-arched spring to do more than any individual leaf should, IMO. That's why I recommend visiting a spring shop and having a matching leaf made from material of a similar thickness to your factory pack, to work as part of the pack. Good Luck!

chopper35nj Posted October 30, 2015 Share Posted October 30, 2015 The Ford springs actually had more arch to them than the stock MJ springs, but keep in mind that the MJ springs were OLD!! and sagging badly, but with the Ford rear springs and 2" spacer in the front the truck has a bit of a rake to it.

chopper35nj Posted October 30, 2015 Share Posted October 30, 2015 Hornbrod, that was for my shackles, Mike never did the bastard pack, we just put in the complete packs. and yes, he did use new shackles. lol Link to comment Share on other sites More sharing options...
