Rear Suspension Flex difference in a 3rd Gen 4runner...
#22
Here's a couple pics:

Fully flexed out... Rear spring removed (kinda fell out). Shocks removed. Sway bar disconnected.

Everything together (shocks/springs/etc). Sway Bar disconnected.
I'd love to see pics of what you come up with. I measured my rear flex to be at 18" (shocks on).

Chris, shock specs:
OME HD 4Runner Compressed 12.95" Extended 21.2" Travel 8.25"
Rancho 5208-Steve has 14" and 22.5", but another site has them as
13.84" and 23.10"
Stock FJ80 Compressed 14.50" Extended 23.5" Travel 9.00"
Bilstein FJ80 Compressed 14.96" Extended 23.27" Travel 8.31"
OME Soft FJ80 Compressed 14.40" Extended 24.20" Travel 9.80"
or you could go with one of those adapters that converts the shock mount to hoops on both ends. Here is something else I came across:

same thing towards the bottom of this page:

Depending on what the LC coils compress to, those OME LC coils might be awesome!

I bet it is the panhard bar as well. It is pulling the axle to the passenger side of the vehicle. But that is just my guess, we should start wagering on it
If it is the e-brake cable it is a good thing you found it now and not when you went to set it for the first time after flexing the rear out!

Or, maybe with the LC coils mounted you could mount them in the standard location and you'll gain an additional 1.45" of droop. It all depends. This is really a trail and error test that you really need a RTI to test easily.

If you had a little more droop and compression, you might make it to the top of Crawfords ramp!
Have you put any miles on these springs to see if they're gonna settle at all? I hope to get mine in today.

If I have enough travel, it might be possible, but I doubt it with the IFS. It get's so tippy. But, I do know having the softer front Tundra coil setup will help to keep the truck more level too.

I know it's a longshot, but it would be awesome! You surprised the hell out of the jeep guys already anyway.

My theory is that if I can keep enough pressure on the drooped wheel (ie spring still pushing downward) and increase the flex at the same time, then the truck will remain more level and be able to essentially make it up the ramp further. Not that I want to be a ramp queen, but it does help out on the trails, that's for sure.

Hey dude,
Well, It actually turned out to be the panhard bar on my truck. My truck sat 1-2 inches lower on the DS because of the overall tension of the rear suspension!
Once my panhard drop bar was installed overall droop on each side was equalized.
Just thought Id tell you.
Oh and I have ~7" of rear lift with no E-brake cable "mods".

Also, I thought this was interested posted by Bamachem:
oh, and the panhard is the culprit. i thought everybody knew that and didn't realize it was being discussed. when the DS droops, it tries to swing forward in an arch around the pivot point created by the upper and lower links. this creates binding at the panhard bar (tries to torque it in a clockwise motion as you look down it's axis from the DS), which eventually stops downward travel as the joints and flex of the bar reaches it's limits. a panhard drop bar will help w/ some of that cause the bar can be torqued easier than a straight bar due to the leverage that can be imparted by the "step" designed into the bar. a panhard drop bracket simply moves the mounting point lower, but doesn't do anything to add any additional flex over stock. put an adjustable panhard bar in that can pivot on the threads (or one w/ better ends) and it will droooooooooooooooooop like crazy. it's on my to-do list, but nowhere near the top.

That's interesting, wonder if I'm over the 3.5" I have estimated and maybe that is why my drivers side sits 1/2" to 3/4" lower than the passenger side. I have Steve's drop bar which is good for 2.5" to 3.5" of lift.
