Shock Specifications Thread

[rmerkushen]

Updated table to include teraflex JT specs and reorganized the table a bit to make it more clear. Will add 2.5 and 3.0 Fox shock specs tonight.

Fox 2.5 and 3.0 added.

Be nice to get the Icon's but can't find numbers anywhere.

second this... anyone have Icon measurements?

If someone reaches out to ICON, I will update the specs table.

FYI: I called Icon a couple times about lengths, they seem shock length to be “Proprietary Information” … Morons, I tried reasoning with them that it’s important to see if they fit, it’s like buying a shoe sized “Adult Men’s” … no dice. Went to a local off road shop and measured myself. I forgot the measurements, but the fronts were 17 or so inches and 11-ish inches of travel. The brake lines were right at the limit and they rode very well.

They apparently don't want their shocks sold to those who aren't running the rest of the components? On one hand, I applaud them for wanting the best outcome and therefore positive feedback from the end users.....On the other, they are missing out on potential sales.

Of all the shocks I have had apart, Icon seems to be the most creative with their tuning and it looks much like my stuff does.......This shows me that some of us put A LOT more work into the product development than others. Most of what I take apart from many of the "big names" is just a simple universal 12 over 15 or #40/#50 stack.

Also pretty sure nobody is getting a 17" stroke shock into a JT without putting it through the hood? 11-12 is about all we can fit up front.

5160 @ 18.25 compressed (1” bumpstop on diesel) will get you 13” of travel … that’s stellar from packaging standpoint. Jeep has done a good job allowing large shocks in these trucks. I still have a LJ and trying to get travel without a ton of bump usually requires a lot of surgery with a plasma cutter and welder … but I just upgraded to 5160 for their efficient packaging. 11” travel front and 10” rear.

but I disagree with ICON, it’s BS they can’t even tell me how much bumpstop I need to run their junk, nor can they tell me how much travel their shocks provide … take the case of bilstein vs Mopar shocks, we are looking at a 50% difference in shock travel, THATS HUGE!!! Some fox shocks can vary greatly in lengths.

instead of selling shocks, they need to sell NOT buy lift height, but bumpstop extension. So a 3” extended shock requires a 3” bumpstop. A step more, the shock manufacture should include a means of extending the bumpstop.

ICON expects me to buy a mystery set of shocks, remove my springs and cycle the suspension, determine bumpstop requirements, wait for bumpstops to arrive, and finally assemble my vehicle, cmon, that’s dumb.

but to ICON’s credit, they build a nice well engineered product, their 2.0 shocks will take your jeeps break lines and driveline to the limit, and also they’re efficient in packaging so you won’t lose a ton of Uptravel, and have a good amount of total shock travel.

my first gladiator had Mopar everything except I threw on some ICON shocks. It was a sport S, manual (so light weight) and the speeds I could do off road on fire roads was IMPRESSIVE … I might have giggled like a school girl flying over mounds at 65-70mph. Felt like a cloud with impressive traction and control. But boy did those shocks get HOT.

You have to go resi to get that 13" number though.......No room for that stroke with the IFP.

Even then, the 5160's 46mm piston is horribly undersized to deal with a 6000lb+ truck unless it's a pavement princess....Who cares about travel at that point? I ran 5165's on my 4,000lb YJ and I could make those fade pretty easy!

Who wants to run a 3" bump spacer on any JT? I know that's what the manufacturers send, but there is SO much left on the table! My Fox 2.5" 11.17" stroke front was all I can fit with a 1" spacer which was perfect for 37's.

I would like to get my hands on a set of Icon JT shock someday, but they just aren't that popular in my neck of the woods. 90% Icon saturation in Toyotas and the other 10% in F150's around here.

One of my clients was comparing our custom tuned E-Cliks on his Clayton equipped JT to another JT in his groups running on Icon and he said no comparison.....He could travel in much more comfort and faster in his truck. I'd love to see this side by side....... He went from Icon to Clayton/E-Clik himself, but as the truck got heavier more was needed.

you’re 100% correct, need reservoirs for the 13”

The problem with Bilstein is the steel body, the icons are an aluminum body shock. Even though my light JT has 2” non reservoir ICONs, I felt they had no problem keeping up, I was hauling ass on fire roads, getting a little air here and there, but damping NEVER faded. I maybe did this for 10-15 miles, I never need a shock to work any harder … but they were quite toasty when I parked.

but yea, shocks and lift companies are morons. Even the Mopar life leaves a lot of shock travel on the table, when I build a suspension, such as my LJ I’m working on now, I leave less than 1/4 inch at max compression. I once dialed in hard stops and shock fully compressed together, hoping the bushings would soak up anything that was off nominal, zip ties never busted off, so that strategy worked fine.

what are these “E-clicks” you speak of? And who do you work for? I’ll give another product a chance… for my third gladiator go around I am planning on doing Mopar lift components without shocks and bumpstop spacers (purchased as pieces). 1” front coil spacer, AEV control arm brackets (Mopar longer arms AND AEV bracket), AEV rear track bar bracket, Spicer driveshaft spacer. I was thinking Bilstein 5160. Or go back to ICON (I like them, even though they annoy me).

PS: I got a fascination for building my new jeeps in an OEM+ fashion. It’s a sick obsession, lol. But if it looks like factory but enhanced, and can put in work, then I’m happy. These are good trucks that don’t need a lot to be great trucks and they wheel so good and comfy, they’re just big. I still love my LJ.

I drive for 10 hours a day off road at times at moderate speeds and sometimes for hours at high speeds, so no way a 46mm/2" shock could work for me. Even the 2.5's get pretty toasty, but seems the oil stays together to about 40K miles before they need servicing.

I was wondering how people were fitting 38-40" tires under a 2.5-3.5" lift until I started surveying the bump spacers that are supplied with the lift kits. Many times when doing a 2-3" lift you actually lose up travel! Those of us with the diesels can use all the gained up travel we can get......

My businesses are https://www.actionaxle.com/ and https://www.overlandvehicledynamics.com/ Websites are still well under construction since I can hardly get the actual work done, but there is some info there. Since I'm an enthusiast in the business that actually owns Jeeps that get used, I found another niche to keep me busy(possibly too busy). I feel the overland (overload) segment popular as it is.....Seems to be grossly under served where drivability is concerned. My main focus is making loaded vehicle drive safe and sporty at speed both on and off road. This thread is where this all started....... https://www.jeepgladiatorforum.com/...-to-those-doing-their-own-shock-tuning.53421/

You can find more info on the E-Cliks at the manufacurer https://www.suspensiondirect.com/shop/eclik I went a few steps further and did a lot of testing so that they work well for those of us who are running on the heavy side with say an Alucab, bed rack w/ RTT, or just towing an RV with a moto in the bed like I do frequently. I do a lot of work with the Fox line right now as well........

These caught my eye. I wonder if the AEV “XP8100” share the same dimensions.

do you have experience running the 8100?

I'm currently running the AEV XP8100s. I'm pretty sure they are the same measurements. Love everything about the lift and shocks except the sleeves in the rear. The Bilstein tuning with the AEV springs are incredible. Check out my post from May 25th in the below thread. I'm currently working with AEV and they have been very receptive.

Just pulled my shocks to look at them and discovered the same problem.I reached out to bilstein, hopefully they'll take care of me
