Dobinsons Suspension - 4th Gen Options
 

Hey guys, my name is Mike Tomczyk (aka Crikeymike) and I'm the former GM of Dobinsons USA, but now running my own company, Exit Offroad. I've been in the industry since 1998 and have always preferred to focus on suspension for 4x4's, since it's something you'll feel every single time you move your vehicle, whether driving to work or home, or offroad for the weekend. Everyone has their own build plans for their vehicle, so no same combo of parts is necessarily right for everyone, which is why we offer such a variety - to get you exactly what you're looking for!!

I'm putting together a post here for the definitive information thread about all of the components we make and offer for the 4th Gen guys. The 5th Gen guys have been having fun over here, but I didn't want to leave you guys out.

Yes, the coils are teal/green/blue color. It's something Dobinsons have been doing for years in Australia as their trademark color, which makes it easy to spot on the trail. They're extremely well powder coated, so if you don't like the color, you could paint over them before installation.

Also, our shock paint is baked on enamel and is extremely tough compared to some competitors. It resists chips, flaking and rusting very well.

Public Notice: Stock/New hub to fender measurements average out to 20" front and 22" rear, and all lift heights are based on that. Many people have 1/2" variance based on age and how the truck came off the assembly line. This video here shows you how to measure your baseline and lifted height:

Added Load Weight.
How much extra accessory weight have you added to your truck? Did you add a 150LB front bumper and an 80LB winch? That's constant weight, and will change which coil to buy.
Did you add our drawer system (hopefully) to the back end (150LBS) or a steel bumper with swing out tire carrier (200LBS)? That will also change which coil we would suggest.
You will want to consider that weight before ordering. If you order a heavy load coil without a heavy load, be warned that it won't ride as it's supposed to and the lift height will be incorrect.

Rear Coil Spacers
We make 15mm thick spacers, which install on top of the factory rubber isolator and below the coil seat on the frame. These are a good idea on older vehicles that tend to lean, add it to the low side
Single 15mm Poly Coil Spacer - to correct vehicle lean - PS59-4025

CV Boot Kits
High clearance CV boots for the outer or inner position of the front shafts. High quality materials, includes all new grease and clamps - great for lifted vehicles with higher angle CV's which are prone to boot failure. Boots have better designed bellows, less likely to rub and make contact with each other for longevity.

All options are listed in the suspension builder page here: https://exitoffroad.com/product/dobi...4x4-2003-2009/

We're new to the USA market (June 2016), so a lot of people haven't heard of us before. And we don't have a lot of real world comparisons yet to all the options out there. We're always asking those who do buy our suspension to write a true honest review with photos and everything after they get it installed and drive it for a while.

It's all very comparable. The coils are made in Queensland Australia, just like OME coils. Dobinsons shocks are twin tube nitrogen charged gas shocks, built almost the same as OME shocks. We have a few differences though, mainly that we use all rubber bushings for maximum vibration dampening and resistance to noise. Some shocks have built-in (welded) stone shields for forward-facing shocks. Here is the link to all the details of our shocks:

Twin Tube Nitrogas

And here's the one for our coil building process:
Coil Springs



EDIT: Update on 12/15/17.

Bring on the kicking and screaming from those who have already bought..... :wacko: :yield:

Due to popular demand and an amazing amount of requests, we have brought our most common 4Runner (and Toyota) coils to the US in 2 additional colors. Red and black. Now these part numbers are available (depending on stock) in classic Dobinsons Teal, TRD Red, and/or Black, depending on part number.

C59-300 (Teal, red or black)
C59-302 (Teal, red or black)
C59-314 (Teal, red or black)
C59-599 (Teal, red or black)
C59-505 (Teal, red or black)
C59-325 (Teal, red or black)
C59-327 (Teal, red or black)
C59-329 (Teal, red or black)

C59-677V (Teal, red or black)
C59-701V (Teal, red or black)
C59-749V (Teal, red or black)


Of course, we would prefer to sell the teal for branding reasons, but so many of you this year have asked us for a color choice, so here you go!!

NOTE: the optional colors are not listed in the catalog, and are not sold on Amazon or Ebay.

Same question for rear spring rate info. I've got Icon 2" lift coils and they are just too soft with even the lightest of loads.

I'll third the spring rates info request, I'd add to it a request for unsprung coil heights, coil wire diameter and number of wraps (coils) per spring as well. Thanks!

Yep, just added

Surely they offer more than one option?

I can do all that except the wraps.


All the info was added up top into the original post by each coil. :peace:

You have anything that will provide 2.5"-3" of front lift with 250 lb additional front weight? Those spring rates look a little soft for how much extra weight I'm running, especially if I remove the swaybar to eliminate my rubbing on it

Regardless, always excited to see more suspension options; thanks for sharing :)

The 314 coils on the 220 struts would be at 3" with that weight. I have the equivalent on my 5th gen with bumper and winch. Too much spring rate can kill the ride quality. We have heavier and heavier options but they're mostly for armored cars with lots more weight.

Got it, misread your post. I just compared the specs to the OME 885 springs I am currently running and they are actually pretty close. Slightly softer and slightly taller

I understand the stiffer springs reduce ride quality, but they are also preloaded with the V8 and a bit of extra weight =) Fair number of people seem happier with the 650#-700# springs. I think coilovers with extra dampening may be my next step

No worries. The next level up is the C59-350 at 380/380, 18mm wire, and 730LB. And then C59-352 at 385/385, 18, and 730LB as well.

That extra 1mm in wire diameter really jumps the rate up a lot.

I'm intrigued!
 

I've been following this discussion as I'm looking to "fine tune" the ride of my 4Runner in it's current state. It has gotten a bit heavier and I'm trying to achieve the factory rake (rear end slightly higher than the front) while clearing my 285's. I'm guessing that 3" front and 3" rear lift would put me there, but spring rates, free length, coil diameter, compressed and extended shock lengths, and bump stop extensions are beginning to drive me crazy. Dobinsons, while similar to OME, seems to offer more options to help with fine tuning. As a point of reference, I had an OME "light" set-up with comfort shocks on my stock-trimmed 3rd Gen 4Runner and LOVED it. We might have to talk as I get closer to swapping some suspension parts!

I know what you mean. Too much info can be a bad thing sometimes, especially when we probably have 12 different front coil options with varying heights, rates, and all that. It keeps our warehouse full with lots of different coils, that's for sure!!!

Do you offer it all as a kit or just piece meal? I plan on getting a front and rear bumper. If I get heavier springs, will it be fine until i get those or should I wait and do it all at once?

Since there are so many options, it's better to piece it together then send it to you as a kit so you'll have everything you need.

If it's 6+ months until you'll be getting bumpers, you might be able to live with it but it won't be ideal. If you think it will be during the year, then yeah, you can get what you'll need now and then be ready for when you get the bumpers.

Yep, a 2" straight rate and a 3" dual rate with no info readily available on specs so they are out for my next steps.

Thanks for adding all the good info here for us trying to fine tune. What's the ordering process? I think I'd like to give some rear coils a try. The dual rates are attractive as softer alternatives to the MT LT coils, and I only have 9.6" rear shock stroke so I don't really need the extra long free length.

No worries. Hit the "direct email" link in my signature and we can go from there.

Our company has been the same way about spec information being released, but we live in an information age, and people are specifically buying or not buying products these days based on what information there is about them. I've already been hit hard against by some 5th gen guys for not sharing, so I gave the 4th genners the info pretty quick. haha
