coil question

2DGJK said:

i was going to buy a 1.5 xfactor from RK for my 2 door but now i'm not even sure about that anymore... i plan on keeping my lift for a long time and 2.5 inch lift is all i need for now. i'm kinda OCD about geometry since it is my DD with some mild trail so adjustable control arm is something i like. i was told that multi-rate coil would fail before linear because most of the time only a part of the coil is used. so it would be greatly appreciated to get some input from you guys and feel free to steer me in another direction.

question:
what are the pros and cons of linear, progressive and triple rate coil (that RK offers)? what is best for long term? or is it best to swap coils after a while to get a better ride quality(on and off-road)?

I'll be the first to admit that I'm not fan of dual rate or progressive rate coils but really, the last thing you need to be worrying about is them failing. I don't know who you've been talking to but if anything, the ride they tend to offer will just flat out suck. Why? Because more times than not, people will load up their Jeeps with heavy parts and gear and the soft end of the coil will get all used up. Sure, you won't sag beyond that but, you will be left riding on the firm side of the coil and that won't feel too good.

Having said that, If you're only looking to run a 2.5" lift, I would highly recommend that you give a basic budget boost or coil spacer a look instead. They will give you the lift you are wanting and without going taller as many coil lifts will and you will still have a factory like ride. You can still get front lower adjustable control arms to dial in your caster but, I would recommend that you NOT get the RK's as the shortest length they can be set at is something like an inch longer than stock and that is WAY TOO MUCH for such a small lift.

Thanks for such a quick response! so would you recommend the 2.5 teraflex coils kit with bilstein? and i'm not familiar at all with all the manufacturer so which front LCA that is adjustable would you recommend for my application?

Evo 1095 leveling kit ($239)- 2" plush coils for the front and 3/4" spacer in the rear. Front will give you around 1.5" depending on how weighted you are.

Honestly, you really can't go wrong with any of the 2.5" coil spacer budget boost kits available. They all pretty much do the same thing and it's hard to screw it up so yeah, the TeraFlex kit will work fine. If you have a 2012 or newer, you will need to be careful about the aftermarket shocks you get as if they are too long, they will allow for too much droop and you will damage your front drive shaft slip boot. Same is true of an 07-11 with an automatic. If you have a 2012-up JK, you can get by with an exhaust spacer like the kind that Rancho makes. It's affordable and easy to install too. If you go taller, you will NEED to get a new front drive shaft sooner than later as it will help to address other issues you will have at that height.

Having said all that, If you do choose to get a coil lift, I might recommend that you give the Rancho 2" kit a look as it'll give you what you are looking for and at a price that is very reasonable. Plus, they have a great rebate going on that you can take advantage of too:

As far as control arms go, I would look at a set of EVO, Currie, Full-Traction, JKS or Clayton. Of the arms I have tested, these have worked well for me.
