Shock length thread
I've found it very helpful to have a list of shock lengths to work with when I have been researching how to get the most travel out of my 4Runner. If you are able to find other relevant shock information, please add.
Here are some of the sites i found useful. Could someone post the lengths of OME shocks or any other relevant brands please?

Apparently, Old Man Emu uses a relatively stiff spring combined with a soft shock. That must be why my OME coils/ Pro Comp ES3000 are brutal.

Ideal shock length for 1.5" lift
This was written a while ago by Mastacox, and I found it very helpful.
So, I have realized that my shocks I have are MUCH longer than most people have for their trucks with moderate lifts... Thought I would get the word out.
I did some research, the shocks I got are 15.25" compressed and 25.25" extended, Rancho p/n RSX 17327, they are PERFECT for a 1.5" HD Downey setup. Stock is 13.0" and 20.75", so these shocks are 4.5" longer. You will, however, need to trim your gas tank skid plate and/or get the panhard bar drop. Also, the bushings are too small, so you need to drill them out with a 5/8 drill bit (the shocks are actually for a 3.5" lifted Wrangler). I have a significant amount of flex in the rear with these shocks, probably about 6" more than stock at the wheel.
My front shocks are 10.00" compressed, and 14.75" extended, Rancho p/n RSX 17010. They are just a little longer than stock (1.375"), but almost the same compressed. Stock is 9.375" and 13.375". These shocks have worked great with the BJ spacers and low-profile polyurethane bump stops.
Anyway, now you know.

The other day, I loaded the 4Runner with about 2-300lbs of firewood and then smeared grease all over the piston rod of the shocks. I then went about crossing up the truck (at speed) and then jumping on the bumper (I'm 180lbs) until I was certain that the wheel had stuffed as much as it ever was going to. I got these pictures of the shock piston rod to show how compressed the shock was when it was fully flexed. The picture shows about 1.75" of unused piston rod. This means that you could get away safely with a 14.5" shock versus the 13.06" shock that Pro Comp supplies.
OME supplies such a shock for the Lexus LX450 (which weighs 6500lbs curb, versus about 5000lbs for the 4runner I think). Here are the specs for the shock:
Part #:OME N71E
Valving: Soft
Extended: 24.4"
Compressed: 14.6"

I have stock bump stops on the passenger side. The bumpstop fell off on the drivers side. Here is the full compression without a bumpstop.
I am thinking about using 3rd gen 4Runner bumpstops as they are bigger than 2nd gen bump stops I believe. I'll find that out soon.

Downey Off Road has these "long travel" shock mounts that would be really easy to duplicate. Theoretically, these cones would allow you about 3 more inches travel- so from 22" to 25" extension.

I'm still using those RSX shocks you found in that post I made a long time ago. The rear bump stops are stock, and I carefully measured my max compression before buying them so I don't have any problems over-compressing them AFAIK.
In the front I have ultra-low profile poly bumps for the compression, and low-profile for droop. Most people recommend that you leave the stock bumps for the droop as you may droop too far and damage a CV, but I have had no problems.
Some pics of front and rear flex (I also have swaybar disco's front and rear). All of the pics are pre-ball joint spacers, tires are 33x10.50r15 BFG A/T's:

The plastic bushings in my idler arm were going bad about every month, so I finally gave up on it altogether and got a Total Chaos Chromoly Idler Arm. Best purchase I've made on the 4Runner, as I suspect its paid for itself in less tire wear and better overall alignments.

More info on OME stuff can be found at:
www.4x4connection.com
This is where I've ordered my OME shocks for the pickup. They carry the full line of OME stuff for almost all offroad vehicles. They've got good customer service, and ship fairly quick.

After all the research, I decided to go with OME replacement shocks for a stock 4Runner, same limited flex as the stock one's. I think they are less than half an in longer than the Procomps. I figure I'll set the suspension up for the best ride possible over gravel fire roads, put a locker in the back to give traction. I put a wooden toolbox in the back on my 4Runner (bolted down) it rides really nicely now. The locker adds enough traction that I am not worried about rear flex as much.
