Default coilovers or air shocks?

I am looking for input from people who have experience with both, if you think you know what one is and how they work then just read.

3200 lbs or less, will be used in conjunction with 4" air bumps, travel will be around 5-6" compression.

right now I have 2.0 SAW air shocks and I am pretty set on the brand so whatever I do it will be with sway a way's.

what can a coilover do that an air shock cant aside from be a coil carrier with triple bypasses or something like that?

I'm thinking about either keeping the air shocks I have, going to a 2.5" air shock or a 2.0 coilover with remote resevoir or a 2.5" coilover with a remote resevoir (50% more piston area than 2.0=cushy jumping)

what would you do and why?

king coilovers with air bypass shocks and air bumps...thats cushy, has alot of flex and could run 80 through the bumps...that will be my next setup.that seems the way everyone is going now because of the rock racing. campbell is running 2.5 air shocks and runs 100 in his moon buggy.that was at k.o.h.he does have air bumps on his stuff though.i think he is running the coilovers and air bumps and bypasses on his rock racing rig though.i think anything needs some kind of air bump or timbren for cushion.

Ill let ya know after sept. 12-14th. we will be doing a comparrison of 2.5 fox air shocks againts 2.0 fox coilovers with remote resevoir at silver lake. so far i love my coilovers. Im not sure if its just my setup compared to before or not but with the coilovers i havent seen a need for a swaybar on the trail yet. Unless you plan on running 65mph for over 3 hours straight in the desert you wont feel the shock fade in the air shocks.

Shannon was running 2.5 fox airs WITH bypasses. only set ive ever seen. But from all the other competitors it sounded like the few 2.0 airshocks that did start to fade wasnt even til the end of the race.

I'm not the least bit concerned about shock fade, it is mythical unless you're in the desert running really fast for a long time.

I spoke to the technical department at fox and they said the 2.5" bypass air shocks are not a good choice, they heat up way too quickly and need to be rebuilt all of the time, "every time out" is actually what the guy said.

if I can swing it I'll probably go with the 2.0 coilovers and run air bumps. these look like the best solutioin for tuning and ride quality. if I run out of money, air shocks it is!

chevotass didnt you put timbrens on yours for a air bump? i am waiting for a set now of the double cardin bumps. how do you like those? they are said to work like a air bump?only 40 a set versus 400 for air bumps. i think for what you want to do bryce the 2.0 and air bumps will be a nice setup...i see the long travel buggys alot on the dunes and they sure do work good with the kings, air bypasses and air bumps.the crawl magazine blitzirk tj has this setup on it.check out the build on pirate. here is shannons k.o.h. rig and the crawl tj.

bypass shocks are no doubt the best way to go.... 2 things are stopping me from even considering them. packaging- $$$$ I'm not made of money.... 300 for the coilover shock, 150 in springs 70 dor a fual rate kit and then 450 for a double bypass and like 550 for a triple bypass 2.0 and then add in the bumps and those are 225 a corner and you have 8k wrapped up into your suspension without even messing with spring rates.

if I'm poor when it comes time to bite the bullet and get them I'll stick with the air shocks, for now the tenative plan is coilovers and air bumps in the 2.0 SAW flavor.

For a 2.0 you will want SAW, but I dont know shit... I just repeat what I hear on the Internet.


I'll fill you in if you want, pm me.

I'm on my iPhone so it'll be in the am.

after running at silver lake id say save the coin and get air shocks and air bumps or coilovers and bumps. i didnt see a big advantage of my coilovers over 2.5 airshocks.

I ran my air shocks at the dunes pretty hard and never noticed any fade or them heating up. I pushed it for a little while intentionally harder than I would normally drive. I had the whole jeep in the air more than once. Immediately after, I stopped & checked them for heat. They were still cool. I've also ran fast down some bumpy trails & experienced the same thing. So, I with my limited experience, I would support the desert running theory.

I've also wheeled with Tab a couple times since we have done our conversions. We are running basically the same wheel base & tire size. I don't think either one of us has seen a noticable difference in ability based on shock type.

As a side note, even getting the jeep in the air, I didn't bottom out the shocks. There was still about 1/2" - 3/4" to go so I'm not convinced I need any bump stops.

Wrong! my jeeps way better! Ya, what Jim said, no real big difference in them for what we do. I dont think your going to be able to push either to their limits with the sort of wheeling we do. Bryce may be able to if hes competing or if someone decides to take up desert racing. Mine does lean a bit more than Jims. While driving and weaving back and forth or on the trail its not even noticable but when turning out onto hard pack and with the rear welded it does lean some. I only have a few inches of uptravel before the bumpstops so its not going to go far, and besides, it had coils before the last rebuild so it was pretty soft before and actually leans less than it did with the old suspension with the sway bar disconnected.
Jims air shocks are nice in the fact that theres a bumpstop sorta built in though. I can feel my front hit if if I'm going fairly fast, like at the dunes or when it G's out at the bottom of a hill I'm taking a run at.
