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

Old Man Emu (OME)
90010 regular 2" lift front struts - 413/543mm
60080 regular 2" lift rear shocks - 368/603mm

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.

It will suit any or the Prado 150 platform vehicles too.
 
So will these work if I go with the new ARB Summit bumper and a winch?

Thanks!

Yes, no problem there. just have to choose the right coil for that extra weight.
 
Here's a side by side with our regular 2" length struts and the longer travel ones with the taller coil seat height.

Also, a pic of our full diff drop and skid plate kit.

I now have the 574 struts with the 314 coils in the front of my 2014 Trail
