Icon rear spring questions.

[comtn4x4]

I weight my 4runner without new front skids tire carrier w/ the stuff on it and pumpkin skid. I was 5660lbs

So currently I have just a tire carrier (80lbs) w/ a 35" spare( 86lbs), a hi lift, traction boards, and a 3rd row... I'm going to go tomorrow to weight again at the truck scale.

And as of right now... my 4runner has a small squatted stance. And I have 3" Overland springs. I'm afraid that with the rear bumper comes it'll squat even more. This will be furtherly worsen by having 6 passengers and all our camping gear.

I think the 749v would be too stiff for that weight. I have about 425# over stock behind my rear axle and run the 701v and it's just a bit too stiff, about 3.25". I have some drawers on the way that should correct it. It rides fine just too tall for what I want. Loaded up it's fantastic.

The dobinson 749v how much lift are you??? I'm looking to replace my 3" icon Overland springs. As even now I just have a hitch tire carrier and it's already sagging w/ my 3rd row... I would like to maintain a 3" which is level with my 4.5" in the front

I can get back to you later today, I’m honestly not sure.

Anyone know of a free vehicle scale in the Bay Area?

Just measured, from the asphalt to the bottom of the rear fender flare I’m at 41.5” and 41.75”, respectively. That’s with 315/70r17’s (saw you have the same tire size). I can measure from the center of the hub when I can get an extra pair of hands.

That’s unloaded, which for me means rear bumper plus full size spare, Autohome Columbus rtt, empty fridge and full tool box.

I’ll have to update my build thread with current stats.

just an update ...

6240lbs was perfect with the 749V but as soon as I load it with my family of 6 ... we're at 7100 to 7200lbs; 749V still good.

but with full camping gear for 5 days ... I'm at 7960lbs and 749V isnt enough ... so I ended up adding bags.

ended up using Air Lift Kit #60920; which was perfect because theres a 1" gap from the bump stops ( I cut 2 off ) so it doesnt restrict flex even at only 5psi.

Damn dude that's loaded up! I nominate you for most loaded 4Runner! I loaded up pretty heavy but nothing like you.

Yeah cuz of the weight I'm exploring the options of getting a trailer and towing that weight instead of having it on top and in the back.

Yeah I have started to consider the same thing. Although the kids are getting old enough that camping isn't "cool" anymore lol.

Looking at a half cut ... a buddy of mine has a half cut 2nd gen with electric and sleeping platform.

But I don't know

camping is always cool!

Yeah I agree, maybe hanging out with the family isn't cool anymore....
Once they can drink they'll be into it again but still won't want to hang with us lol

Lol ya they'll come back around. Maybe having a friend or two along will help them like it more.

Hi all,

Sorry to revive an old thread but I don't have enough net cred to start a new one...

I have a 2015 4runner trail. At the moment I have installed a Victory 4x4 full roof rack and a Thule Tepui Autana 3 roof top tent (rack and tent about 150-160 lbs). Inside I have a GooseGear (style) platform (about 40 lbs). During the summer I have an Iceco VL45 refrigerator (45 lbs) mounted on an Iceco slide (about 30 lbs). Empty weights. Also during the summer I carry food and water for one person, and miscellaneous things that probably weigh in at 100 lbs or less. Front of the rig has a hidden winch mount (SDHQ) and a Warn VR Evo 10s.

I have bilstein 5100s in the front set at 2.5 inches, stock front springs. Money was an issue so I went with 1.5 inch spacers and some eibach shocks (stated for 0-1 inch of lift) in the back. It was good until I installed the fridge and plate, then sagged in the back by about a half inch.

Money became less of an issue and I upgraded to Icon 52700 2 inch rear springs, same shocks. At that time I had removed the fridge for the winter, but installed the rack and tent. Was just level. I didn't want to put the rest of the gear in the rig and have it sag again, so....

I pulled them and installed the Icon 52800 3" overland springs. They ended up lifting the vehicle over 4 inches over stock. I immediately knew I didn't have enough shock, so....

I installed the 56505r Icon shocks (1-3" lift with remote reservoir). Shock problem fixed. However, as soon as I installed the overland springs I noticed a driveline vibration between about 20 and 35 mph. So...

I installed Icon adjustable rear upper control arms. Set them to about 3/8 of an inch longer than stock. The vibration is better but I can still feel it.

Now the fun part. Am I seeing far more lift from these springs than I should? I'm still sitting at about 25.5 inches from center of the hub to the fender in the back. I measured a stock 4runner and it was about 21 inches, so still 4.5 inches lift after about 3 weeks and 1,000 miles to settle in. I know I'm not really loaded down right now, but Icon says unloaded they should net about 3 inches of lift. Secondly, am I being totally over sensitive about the vibration? I mean it's very slight, but this thing is my baby and my OCD is on fire. I know the springs are stiff, but I don't want to swap them back out...

Sorry for the long read, I'm trying to get all the info in there at once.
