Hey guys,

We have been working on a new set of struts and shocks for the 5th Gen 4Runner, that will also work on the FJ Cruiser too. We wanted a longer travel front strut to get the most out of the front with having a diff drop kit and UCA's installed, and be the correct length for a true 3" lift. 575mm is the maximum we can go, and we were able to get that out of our twin tube design. The compressed length is 435mm. Twin tubes have been great long lasting shocks for several decades, and we wanted to make sure people can afford them too. These were made with the same valving as our 2" struts, which are considered a comfort ride, front and rear. We also raised the seat height on the front (it's a fixed seat, not adjustable) from the standard 213mm to 226mm. That extra 13mm will give about 1" extra lift height, so this means that by running a 2" coil on these struts, you will reach 3" of lift. Although we'd love you to, you don't have to use our coils.

The rear twin tubes are 432mm compressed and 730mm extended. For these, you will need some longer coils (we're making variable rate progressive 3" coils, due here in late January) so that they don't fall out (2" coils won't work), as well as 3" bump stop extensions (we're running Metal Tech), and a longer rear brake line.

Our 4Runner (as shown in my build thread) has been running these longer lengths for 6+ months and the flex has been awesome. Have to point out here that these wouldn't work with a KDSS vehicle, since the rear sway bar would inhibit the flex so much.

We're also working on our own UCA's, but R&D is painstakingly slow, so we're still a few months away from getting those complete.

Once again, here is the summary and comparison.

Dobinsons
GS59-574 - for 3" lift - extended length front struts - 435/575mm
GS59-575 - for 3" lift - extended length rear shocks - 432/730mm

GS59-700 regular 2" lift front struts - 432/541mm
GS59-701 regular 2" lift rear shocks - 362/583mm


I've been searching for a while for some good references to other brands and their length specs, but haven't found solid info. If anyone has it, please share and I will add it in.

Daaaaaaayyuuuum. That pic induces a bit of KDSS regret.

But then she rode great at 85-90 on the drive home from Vegas...

Tell me about it.... my personal 4runner has KDSS, and it frustrates the hell out of me sometimes.

Looks great! Very happy to see the products Dobinson is coming out with for the 4runners.

I assume you removed the rear sway bar for that flex?

Oh yeah, that thing was kicked out of there a while ago

Finally...reputable and local! Looks awesome!

Thanks man. Come on by when you have the chance!!

I'll definitely try and find some time to sneak down. I'm about 30 minutes North of you all (you're in Doral correct?). Maybe after the holidays!

How much compression is left with the 3" bump stop extensions?

Time to pullout the forklift again and get that for you. I'll reply when we have it handy.

Alright, here are some more details to show the bump stop (with the 3" extension on there).

1st photo is bumper stop just touching and remaining shock left is about 45mm
2nd photo shows shock remaining, 45mm
3rd photo bump stop compressed quite a bit
4th photo shows shock remaining, 40mm
5th and 6th are just 2 other angles to show droop/down travel

With only a 2" bump stop extension, it wouldn't be enough, especially since the bump stop can compress further.

Also - the shocks we have on there now are our rebuildable shocks that we have been using to get all this stuff right. The twin tubes we're offering won't have the exposed shock rod like in the photo.

Any pics of the wheel stuffed when on the stops?

Looks great so far!

Yeah, I had those pics already. Here you go:

Yep, in Doral!!

Seeing the photos showing the rear suspension at full droop prompts me to ask this noob question.

What component/s limit the maximum downward travel for the rear and front suspension?

I lifted my old 2WD pick ups but there, the leaf springs limited the downward travel in the rear and bump stops for the upper arms up front.

Nice looking ride, btw!
