Dobinsons 5th Gen T4R Suspension options - from Exit Offroad

[mattb124]

I have about 1,000 miles on my C59-300/C59-599 lift and it has been a nice upgrade. It provided the right amount of lift and the ride is just a bit more firm than stock (less stiff than I thought it would be), but it has substantially reduced the nose dive on breaking. Mike was great to deal with through the selection/ordering process. All in all, very satisfied (despite 4WP making every effort to thoroughly annoy me through the installation process).

2016 T4R SR5P w/ 3rd Row

Before Measurements (w/factory tires and suspension)
LF 34.375 RF 34.5
LR 35.75 RR 36.375


Installed:
C59-314/GS59-700 Front
C59-327/GS59-701 Rear
Spidertrax 1.25" Spacers
SPC UCAs
285/70r17 Falken Wildpeak AT3W

After Measurements: (w/lift, tires, & alignment)
LF 38.75 RF 39.0
LR 39.25 RR 40.25


UCA Angles are pretty bad. I have a diff drop kit and plan on installing it shortly.

SPC UCAs were great for allowing the front wheels to move forward in the wheel well. I don't have the alignment values, but everything was returned to within spec and no BMC or rear mud guard work required. I did trim the front plastic and move the front wheel well plastic forward to eliminate a slight rub, but it was easy work.

The truck is my wife's daily driver and she loves the lift and the look. We have taken it on several long drives and have no complaints. It's been a good product and we're very pleased with the purchase.

Hey man, how's the ride with the stiffer rear springs when unloaded? I plan on getting more weight on the back (steel rear bumper w/ single tire swing out) but want to get the Dobinsons suspension first.

The ride is noticeably firmer than stock, but that's not a bad thing. Nose dive under braking is much reduced. I think the E-rated tires play a big role as well in regards to ride, we have ours set around 34-35 psi and that seems comfortable for us.

Can you recommend rear springs for my setup?

I have a 2018 ORP with KDSS. I am running The TRD bilstein Kit for FJC TT Ultimate . TRD 6112 front shocks with 600 pound Eibach coils and 5160 rear shocks with stock coils.

I love ride and handling, but need some 1-2” of lift, plus some weight full steel skid set including fuel tank, hard shell RTT, Sliders, Warn hybrid bumper and winch, etc. I also have an APOC trailer that I pull regularly. Finally, I have had a Proline dual swingout on order since January. I am hoping it will ship some day, so I need to account for that weight too.

Any suggestions for a mild lift tat won’t settle when I install rear bumper? I am thinking the c59-727.

Good luck with your installation... I LOVE my Dobinsons lift! I received mine on Thursday of last week at 2:30 PM. I was so impatient, that I had everything installed by 10:30 PM the same day haha!

How was the installation? Did you run into any issues? Just curious as I will be hitting the ground running when mine shows up. I have on order 302/700 front and 723/701 rear. Can’t wait!!!

Absolutely zero problems! It was a little strange to do an installation and encounter no problems, slowdowns or hiccups. Just take your time. Plan in advance like having a jack ready to keep the LCA with rotor, half shaft and caliper from dropping, etc. Pay attention and you’ll be fine.

I used two ratchet straps to make dealing with the front KDSS easier. One strap to keep the KDSS from extending and the 2nd to pull the hydraulic ram back toward the LCA, so you can reattach the sway bar end. Ignore the Dobinsons suggestion to loosen the KDSS bleeder screws. I just followed a couple of the tutorials dealing with KDSS posted on this site with a few subtle changes.

Up front, I don’t recommend that you disconnect the LCA like one of the tutorials. Instead I disconnected the ball joint at the UCA and also the tie rod end. I used a kayak strap with a cam buckle wrapped around the UCA to control dropping the LCA with rotor and half shaft to allow enough room for removal of the old strut. Same for the new Dobinsons strut.

The rear is easier. Just pay attention to the brake lines and the ABS wires. DON’T tighten the lower rear shock bolts until the tires are on and the vehicle is totally on the ground supporting its own weight. Otherwise the lower bushings could be immediately destroyed or fail quickly. Once the 4Runner is on the ground shake the entire truck a bit, then torque the rear bottom shock bolts to 72 foot pounds if memory serves me ( double check that torque spec before you begin).

Good luck!

Thanks for the details ProfessorP. That’s awesome you had no hiccups.

I would go with the C59-729 in your case. You have a lot of weight in the rear. Dual swing out is going to be 200 to 250 lbs. Full size spare that hangs off the rear, not under the frame near the axle. You have a steel fuel tank skid. Add RTT and sliders. You're already over 400lbs off the rear. Add in cooler/fridge, jerry cans with water/gas, gear, people, and you can see where you're closer to 800lbs. Then add the trailer.

Also 600lb springs up front are not enough. I'd get at least 650lb springs up front to support your bumper and winch.

Can anyone confirm that the 505 rear springs actually give a 1.5" to 1.75" lift on a stock weight 5th gen 4Runner?

I need to achieve no less than 1.5" after install, but 1.75" would be even better.

Yes, 1.75" with no weight at all, 1.5" with some weight. You will not get less than 1.5" of lift unless you add more weight.

Yes, quite a lot of lift. I have stock tires (2018 TRDPOF), aluminum RCI skids, sliders, and the rear sliding tray. The lift was more than I envisioned (seems like 2" but I did not measure). I am swapping them out for the 599s. If you have larger than stock tires, or notable extra weight, they should be fine. For me, it's an aesthetic choice of too much tire gap; they ride wonderfully.

Looking for recommendations for a lift. Hoping to get around 2" Front and 1"- 1.5" Rear loaded. So far I have a full length roof rack around 90 lbs and will probably have a RTT for some trips in the summer that weighs around 200-260 lbs. No plans for a front/rear bumper at this point, but may add skid plates down the line.

Here is what I am currently thinking:

Front
C59-302 or C59-314
GS59-700

Rear
C59-505
GS59-701

Also thinking about upper control arms, are they recommended with this setup?

Thoughts?

 

[GripT4R]

Yes, 1.75" with no weight at all, 1.5" with some weight. You will not get less than 1.5" of lift unless you add more weight.

Sounds perfect for my application.

My 505s gave me about 1.75 to 2 inches of lift in the rear. Very happy with the results.

On the front, C59-302 will be 2.5" with stock weight. If you think you'll add skids and extra weight, you can put those on then have the lift height come down with more weight added. C59-300 is the 2" front coil with no weight.

Rear, C59-505 sounds good for your vehicle, since 98% of the year it probably won't have the tent on the top. The tent would have the rear drop 1/2" approximately if it's 200lbs.

UCA's improve handling and front end ride quality, and at 2.5" it would be a noticeable improvement, as guys were saying just a page or 2 ago.

Thanks!

In that case I may go with a more even lift to start, C59-300 and C59-505, and then reevaluate again when the time comes as I'm planning on starting with 255/75/17 or 265/70/17 tires.

What's the difference between the 302 and 314?
