I am fully aware YJ has leaf springs, I am racing with it for three years :-)
My current RE suspension lift is busted (again) so looking for an upgrade. RE and OME are now producing their lifts in India and Thailand, so they're out of question.
My first thought is an upgrade to Deaver leaf packs OR a totally different route - coilovers front and coils rear. Just gathering info, no decision yet.
Pirate4x4 is a nice and informative place, but they are into crawling with lots of lift ( = very long coilovers), super big tires and I'm into speed with small lift and tiny tires :-)
Any input appreciated.
Although the POR comment was an obvious joke, I would post over there anyway. I know next to nothing about coilovers, but as you pointed out, they do alot of different things over there. I don't believe there are a huge number of guys on this board that would have the kind of set up you're looking for??? (to me, a 2.5" of lift seems moot for coilovers, and I honestly don't know if it's doable???) You may also try posting in one of the other forums... perhaps even the TJ forum, which is more geared to coils and the like.
Also, fill out your profile. That will be more helpful. Depending on what you have now, I would'nt waste the $$, time and effort in coiling a turdy 5 rear.

@ Rock Worm: thanks for hint. Have updated the profile a bit as well.
@ Joe: It seems that Fox , SAW and King don't care too much about my (our) inventions. I have already contacted them when ordering my current shocks and they did not provide too much info. I had to specify my shocks very precisely, including type of shock mounts on YJ. Funny, I know. Would expect that they will be able to advise and propose a solution, but that was not the case.
You can buy coil conversion kits. I assume you know this. I have heard spooky things about coil conversions on yj's but they keep making them so I guess they must work when done right. Full coilovers front and rear would be the next option but that will require some fabrication. Since you seem intent on keeping the yj and spending a fair amount of money on a new suspension the fabrication aspect shouldn't be an issue. You can have custom rates spec'd for the springs and shocks. I have no idea what you would spec. What kind of racing are you doing where you are breaking leafs and only have a 2.5" lift? bds makes a good set of leafs (i don't know if they are sourced overseas or not).
The coilover kits available all have huge lift, are expensive and use too many compromises (buyer friendly, easy install). IF I go with coilovers, I'll probably use Toyota Landcruiser 73 radius arms front and rear. Radius arms front and rear are also used in LR Defender, Mercedes G, etc... so I should be OK.
I'm racing in so called marathon desert rallies. They take place in Sahara desert of North African countries (Tunisia, Libya, ...). It's all about navigation, durabilty and endurance. Some pics:
OME lift, that I was abusing before, started to sag badly so I replaced it with RE. Got them with Made in India sticker on them.
Anyway, they died soon and in two stages:
- First I noticed that the shortest leaf on right rear end remained bent straight (was not aligned with other leafs anymore, which is quite strange for spring steel)
- Bit later I broke the main leaf in the same leaf pack and the game was over.
What kind of spooky stories have you heard about coilovers? Am really not dead set on coilovers, just gathering data in order to make an informed decision.
Does any of you have a first hand experience with Alcan or Deaver leaf packs?
He is not talking about coil conversion kits, he is talking about a coil over suspension.
As in long arm, 3-4 link, radius arms, etc with coilover shocks. It's a totally different animal.
Most coilovers I have ever seen use 2.5" diameter springs but it all depends on what spring rate you want and shock travel and it's impossible to tell you what will work until you have fabbed something up.
Where is your top mount, where is your bottom mount, how much do you want to cut the inner fender, etc?
And for the record: The guys over at Pirate are not looking for lots of lift with big tires. Quite the opposite. For crawling, you want as low a COG as possible with maximum articulation.
Minimal lift for the largest tires you want to run with the most amount of flex (uptravel and droop). That's why they need long shocks.
Not trying to be a jerk but your question is way too vague for anyone to give you a useful answer.
