Icon Coilovers

Update*

Well today i had the rear shocks installed on the truck. and i am kinda thankfull that i did have someone else do the work instead of tackling it myself. the 100 buck to install them and save my self hours of frustration was very well worth it. the icons are about 5 inches or so taller than my tokicos that were on the back of the truck. the shop struggled with the install and ended up spending about 5-6 hours on installing them. whew if i did that i would have been hella pissed and cursing at the rear suspension on the 4runner because of it. it ended up lifting the rear of my 4runner up another inch or more on the 906 coils. and my guys said that it rode way better than previously with he new shocks. the bouncy rear end feeling was gone. i am excited to drive home tonite and feel the difference for my self. i will get some pictures as well.
 
Weird, shocks gave you lift?!

If they are 5" longer, then wouldn't they be bottoming out/causing problems with seals? Are you sure you got the right shock size? They should be maybe 2-3" longer (extended) at most...
 
The Icons are 5" longer?! I hope your old shocks were real short. If the shocks are too long, you won't get full compression of the suspension to the bumpstops before the shock bottoms out. Bottoming out a shock is very hard on the shock. Too long can also allow too much droop and sometimes the coil can fall out on the trail.

yes the shocks gave me lift. i dont think they are 5" longer but that is what the guy said when he installed them. the had a hard time doing it and the basically said the rear end had to drop. i was looking a another personas info that was posted on yota tech about the same shocks and he said they gave him lift as well.

i am hoping they are not 5" longer if they are then something is wrong. and i am going to contact icon and see if they sent me the wrong shocks.

i will snap a pic of the stance in the morning.

Well after reading through that post, it answers a lot of questions on why it was so hard to install, and why you've got lift. You should be fine.
 
They could give you a touch of lift. It sounds like the oil/gas has some pressure behind it. Most shocks have pressure (to keep the oil from foaming) but you can compress them by hand. It sounds like these need some extra help to compress them to put them on. (I usually just droop the axle to the lower eye)

I'm wondering of the valving has anything to do with it? That mixed with an increased amount of oil (extra oil because of the resi's) could make it hard for the weight of the truck to really compress the shocks at ride height.

OP, what is the valving on these suckers?

hey Guys driving home last night was nice wit the rear shocks, but i am a bit concerned i have the wrong rear shocks. the s/n numbers on my shocks dont match up with the ones in the link i posted on the last page. which may explain why they were so hard to install on the 4runner. i also hit a big dip yesterday on my way home which i normally always do anyways, but the result was a loud clunk on the rear end! i have called icon this morning and left a message.
 
hey guys any ideas on why there is a loud clunk from the rear after these shocks? i dint see any marks from anything hitting the shocks but i am concerned. i really dont think the loud noise is normal.
 
Possible loss of Nitrogin charge on the shock(s). After reading about the difficulty to compress the shocks, maybe the installer released some/all of the 250psi charge to make it easier to install them? If there's no NO charge in the shocks, the piston will slap around in the remote resi.

I lost a charge on one of my front COs and thought it was a loose swaybar something similar. That's how loud it can be.

thanks for your input John. i am sure they didnt release any presure in the resi's as i went to ask today and pick up my old shocks. the actually drop the rear end on a tranny jack to get them on as i stopped by during the install.

Possibly bottoming out.
I would measure the shock body and the length of shaft showing. The shaft is almost the length of the body (minus ~1") (on a reservoir shock). Then measure the distance from the axle to the bumpstop. It the exposed shaft length is shorter than the distance to the bumpstop, then I would consider it the wrong shock.
There is a balance between short enough to allow the wheel to fully compress to the bumpstop with the other wheel at full droop (which will be shorter than if both wheels are fully compressed). And allowing as much droop as possible. This is further complicated with taller coils and still allowing droop from ride height.

No, the valving nor the extra oil in the reservoir would increase lift. (valving is just resistance created thru openings in the piston to increase or decrease damping)(The reservoir allows for an increase of oil volume to dissipate heat and decrease fade). The pressure that the nitrogen (that is inside to minimize oil foaming)

What he said, valving nor the resi will increase lift.
The nitrogen charge will give some additional lift. When I stopped by Icon to have my shock recharged, it lifted the front close to an inch after they let the initial charge out.

Good to hear they didn't let the charge out. Now it could be that the shock just lost charge or they simply forgot to charge it before they packaged and shipped it.
 
An old mountain bike trick. Since your shafts are exposed, put a zip-tie around the shaft and pull them tight. This way you can see how much the shock compresses after driving.
 
ok after driving today there is definitely a problem. my diver side rear shock is hitting the frame going through dips and coming out of driveways i am sure of it now. how you ask? there are scratches on the top of the external resi bracket. and to make things worse the truck doesnt ride as good as yesterday.

I'm gonna call the dealer that i bought through as well as icon if necessary in the morning.
 
I love them!

I have a set of icon coil overs on my front with the total chaos upper control arms. I absolutely love them!!! Best coil overs ever. I'm rocking the OME rear set and its working great as well! You going to love your new set up.
 
at the moment i am not to happy. i waited a month to receive my rear shocks from icon. then when i receive them we install them and the same day they get installed i have problems with them. i am going to icon tommorow and have them look at the shocks and address the issue. i am tired of driving around in my 4runner and having to slow down before dips and speed bumps because if i dont the shocks hit the frame and damage the piggyback resi mount. this is just not bueno in my book. i will hope for icon to make things right if not you guys will be the first to hear and i will be taking legal action.
