My T4R is also a daily. The setup Mike put together for me rides better, than most if not every stock suspension I've ever driven (talking SUV, and pickups here). It may not be as soft, but I feel the way it handles overall is important versus "not feeling any pot holes or cracks." I did post some pics just up a few posts.

I should let [MENTION=144682]Kfog375[/MENTION] jump in on this one, as he just installed a set onto his GX470 a few weeks back, the same parts that would go on a 4th Gen. His thread is here: http://www.toyota-4runner.org/4th-gen-t4rs/239204-dobinsons-mrr-have-arrived.html
The MRR's are only available by special order right now, which requires air freight from Australia. All of the info about them can be found here, and more on Kyle's thread.

Like Mike said, I put the MRR's on a few weeks ago on the TOO GX and it's been a really nice ride since. The ride has been really nice, and install was a breeze. Set the collars to 8 3/8" on the driver side and 8 1/2" on the passenger.
I've been pushing these pretty hard on my GX folks, its really an incredible value (even with the air freight). I really think they're going to shake things up once stocked stateside.
I've actually got a set of the 675V progressive coils headed my way to get some more data on how the MD application works with the GX/4th gen weight (with no bumpers, etc). We're thinking it'll be around 2.25-2.5" of rear lift, i'm expecting the ride to improve some as well.
Any specific questions you've got?

Installed the 675V medium variable rate coils yesterday on the Treaty Oak Offroad GX. The ride is definitely improved when paired with the MRR coilovers and shocks. The medium variable rate coils only provided about 1.75" of lift vs the 2.25" I had with the C59-314 linear coil, but with the improved ride I think i'm going to leave them. I need reduce a little preload up front by about 1/2" to get a little rake back.

Cool, I just processed and shipped that order.
It will be riding high without those bumpers on there!! You bought the heavy front and rear coils with that kit.
My order just came in from your guys Amazon USA store. You sent me the C59-727 springs for a 4th gen v6 heavy load but it isn't listed as an option in this thread, will these still work with the gs59-637 shock?
EDIT: NVM I see you just replied to my previous post so they must be good to go! Yeah I will be riding high until I get the bumpers, but I don't plan on it taking longer than a couple months for me to get the funds for them haha

Yes, and yes.
They're the same as the 327 coils, but offset heights, which is better for a 4th gen to compensate for the lean. Put the taller coil on the lower side.

Sorry for the slow response, was out of service for a while and forgot to respond. So unfortunately I haven't gotten the 677's, none of the trades have worked out so I've just been dealing with the saggy. I love the ride of the 675's just not the height when loaded. If you have a full 3" lift front, carry any extra weight, and like a raked look (and have long enough shocks like the LT's) then I would recommend 677s. If you get them and they are too high for your taste then you know who to swap them with! I have not have the MT LT springs but I've heard they are too stiff and that's really helping these Dobinson guys get some love on the LT side. They know how to flex!

Well let me know if you decide to part with the 675s in some fashion other than a trade. I am near certain the 677s are going to be way too tall for my GX. It already has an added 3/4" in spring perch height from my rear airbag-to-coil spring conversion. And I don't carry around a lot of gear...
Installed my new Dobinsons springs. 300's in the front and 599's in the rear. Bilstein 5100 shocks all around with the front set to the lowest clip. Tires are 265/75-16 Cooper AT3's.
Fender to ground is 37" on both fronts, 38" on the left rear, 38.5" on the right rear. This is using an OME 10mm rear trim spacer on the driver's side.
Some comparison pics to my old Moog Coils. Fronts were the V8 version, rears were the stock replacements. I previously had the Moog V8 coils with the 5100's set at the 3rd notch and now with the Dobinsons 300's up front with the 5100's at the lowest clip I am sitting 1" higher in the front. Also, I gained about 1.25" in the rear with the 599's vs. the Moogs.
The Dobinsons design seated much better in both the front and rear of the truck during the install.

Can I run the Dobinsons Springs with my FJC TRD Bilstein shocks? Are they compatible?
Crikeymike

Yeah, they should be fine. They're just the 2" OE Bilstein TRD shocks/struts, right?

Yes they sure are. Would you rather me PM you or email you regarding a possible order? I just have a few questions.

Good to hear man!! The stance from front to back looks really good.
Those side by side shots with the coils you took off are very helpful. It's funny how much shorter the old coils were on the front compared to ours.
I'm also not sure why some stock coils don't have flat tapered ends so that they seat better against the rubber top strut mounts.

Those tapered ends that your coil use are much better. They seat much easier. I'm definitely happy with my decision to go with Dobinsons.
I am going to replace the suspension on my T4R and have narrowed it down to 2 variants...i think.
A little history first though.
Stock 2007 SR5 v6 4wd approx 130k on, as far as I know, original suspension.
I actually have a passenger side lean, not sure why.
I want to do a touch more than just leveling the front to rear.
Perhaps 300 coils frt and 505 or 599 rear coils. Always have a tool bag, big backpack style that is FULL, ropes and rigging gear and jumper cables (50 to 70 lbs max).
Dobinsons shocks and struts pre-assembled sounds nice and easy but how to correct for lean. Do you put spacers front and rear drivers side.
Bilsteins 5100's with Dobinsons coils. Settings on frt driver side Bilstein?
Of course cost is an issue and I figure either option will be roughly the same once the Bilsteins are assembled by others.
Thanks in advance.
