Your favorite coil spring?

I have no idea what springs are in my jeep (PO installed them), but they seem to stiff for me. SO what is your favorite coil spring manufacturer? Is a dual rate spring the way to go? My TJ is not my DD, so on road ride quality is secondary behind flex and stability off road. Give me your opinions.
 
My next purchase will be currie (under savvy website) dual rate 3" coils and Fox 2.0 shocks.
While coils ARE important, controlling rebound and compression is just as important (WERA/NESBA/cornerspeed racing school experience taught me that anyway....I'm not that smart)
 
Thanks guys. I had RE springs on my ZJ and they were to soft, kept bottoming out, but then again the ZJ weighed over twice what the TJ weighs. I like curries stuff and their dual rate springs seem nice.

A spin off question, I have 33" TSLs that measure at 34" on my TJ, what spring lift height should I look at, 3" or 4"? I do have a 1" BL for the flat belly.
 
Re coils are to soft, some rk coils don't give the stated amount of lift, metalcloack and Currie coils seem to be pretty nice
 
I know a couple people running Metalcloak springs that are very happy. They have a very long unsprung length for people planning on long down travel. The only problem for me is that they start at 3.5" for the TJs and im looking for 1.5-2" so ill be going with OME springs.

Metalcloak springs seem nice too
 
Currie/savvy seems to have the spring game down with their true dual rates, metal cloak claims it's a dual rate but it's really just dead coils that keep the spring from falling out. Rock crawler seems stiff as hell and have a short free length. As far as RC or RE haven't used them. You can find spring lengths/rates online for most the manufacturers so you can compare them. I actually called Blaine johnson(savvy) and talked to him about springs a few years ago. Then I called Matson over at metal cloak and he was kinda an asshole, pretty much told me they use dead coils to keep them from unseating.

I'm not a huge fan of "LCOG" people are trying to build for. Mainly because most will try and run 35s on no lift limiting the uptravel like crazy with bumpstops then they never flat belly it so you're sitting at 14" of belly height and turtle it everywhere.

Stability is one of those things where I wouldnt rely on your springs for that, good anti-rock and outboarded rear shocks make a world of difference. As far as what type of spring you run, a true dual rate is the route I'd go. It might be the wrong thinking, but I look at it more like a coilover when you run dual rate springs and separate shocks.

If there's anyone in the world that loves him some Blaine, it's Blaine :rolleyes:

Can't knock his knowledge, but damn....his attitude towards others is not the best

Fortunately I get along with him and Gerald lol. But that's not saying we have disagreed on things or certain ideas lol.
 
I have Off Road Evolution 3" plush ride springs on my JK. I love them, they're pretty soft. No clue if EVO makes a lift for a TJ now. I know they do make some armor for TJs.
 
I don't have a TJ, but my SAS trooper is running TJ coils up front. Originally it had 4" procomps, which have a 160-180 lb/in rate, and turned out to be too soft for me (more to do with on-road/speed comfort). Went to 3.5" RE coils, which have a ~240 lb/in rate (edit) and the ride is a hell of a lot better. So at least for reference, there are those two rates.

The only problem I have with the RE's is they unseat pretty easily even with my currently limited down-travel. I have a lot more droop available, but it's annoying as hell to listen to the coils popping in and out of the buckets, so I'm going to have to figure something out.

Does anyone run upper and lower coil "keepers"? How much stretch beyond free length would start giving you problems with over-fatiguing or killing the springs?

Are the springs even near coil bind at max compression? Without the bumpstops, Is the up travel limited by tire clearance or the shock bottoms out first? If it were me I'd squeeze every inch of up travel I could get out of it and use the whole range of motion of the spring.

I run retainers top and bottom on the rear of my JK and I haven't noticed any sagging of the springs back there. Granted those are a linear spring.
 
Had to edit prev post, the RE's are actually 3.5" springs and rate is 240 (checked their website).

As I recall it, the springs aren't very close to binding at max compression. The coils come unseated in the last inch or two before my limit straps kick in, but that is going to change as soon as I finish my dual cases and have a front driveshaft long enough to keep from binding up so soon.

Uptravel is limited to 2.5-3" by panhard/steering to frame interference (need to notch it more) and I've set up my bumps and shocks around that. Tire clearance isn't an issue. I could adjust my upper coil mounts lower to have the coil closer to binding at full bump, but I'd have to run a shorter spring and/or potentially lose some travel unless I compromise on-road stability with a softer rate...maybe some of those fancy dual rates would work. I think I'll start with some keepers until I get to the frame-notching phase and then do it all at once.
 
Personally, I'd notch for your track bar and steering and then set your shock mounts to fit that so you can use the whole range of travel and maintain the same ride height. That's why I was asking if they were close to being at coil bind.
Going with a shorter spring is gonna just make it worse.

That's what I was thinking as well. But even if I notch for more uptravel, I'm still leaving plenty of downtravel on the table. I've sent a few emails out to the tnt and synergymfg folks (since I've got a TNT y-link), to see if they can give me their coil spring specs.

e: sorry for the hijack!

Dual rate, cheap, ride nice, flex well.
