Dobinsons MRR/MRA Suspension Questions

Calling all Dobinsons MRR/MRA suspension owners for a little help/tips with my upcoming install Friday evening and Saturday morning. I appreciate every and all replies!

(I did search for these answers throughout the forum and I read through a lot of the Dobinsons threads but I was not really able to get the answers/pics I was specifically looking for)

First, I have to say a big THANK YOU to @Crikeymike for getting me all set up with my order and the help in my many questions on the quest for a successful new suspension set up.

I am looking for everyone else who has this set up to please provide some feedback on the following:
  1. Can you please provide pics & location you mounted your remote reservoirs - did you use the provided mounting hardware or did you have to come up with a different method? My concern is the long line from the shock to the resi and it rubbing or getting caught up somewhere. I also want to make sure I have easy access to adjust the settings.
  2. Any specific items for this MRR/MRA setup I should be on the lookout for when completing the install?
  3. What measurement did you use from the bottom (middle of the hole) of the shock to the lip of the seat to achieve your (x)" lift? I am planning for 3" and know it will settle after the initial install and drive before alignment. Did you have to make any adjustments after they settled?
  4. What settings are you running for your low speed, high speed, and rebound for daily driving and offroad driving?
  5. What alignment numbers should I be after with the Dobinsons UCAs? The target is for 3" lift in the front and 2" lift in the rear

I am fairly decent in the garage and have done all my own installs. However, this will be the first suspension project I have done and for me, knowledge is power. I do have buddies who will be there to help and support me, so I will have some experience in there with me.

I really appreciate the feedback and suggestions I look forward to reading!

Thank you!

Full disclosure, I don't have the MRAs, but I did help a good friend install his, so here's what I can offer

For the front resi's we used the included mount, some stainless hardware we had laying around (bolt, washer, washer, lock washer, nut) and found a pre-existing hole through the body "above" the shock tower. Essentially the resi's sit just above where the 3 14mm nuts are on the top hat. Installing the hardware for this bolt hole definitely required 2 people and some patience, partially because the passenger side was under his second battery and the drivers side is under the added tray to hold electrics.

For the rear resi's we used the included mount and sandwiched it between the bumpstop and the frame using one of the bumpstop bolts. He's running Durobumps bumpstops, which afforded plenty of "squish" while still tightening down fine. If the hoses for the resi's were about twice as long you could go for a more traditional mounting location like many other companies use.

Especially for the front, make sure you have the hose for the resi's going in the direction you want before you place everything into the upright; part of this goes along with us trying to find a location to mount the resi's and a lot of trial and error.

OH! The rear's, maybe we are just really inexperienced, but allowing them to extend while keeping them compressed enough to fit into the bottom mount was.... interesting. I think we ended up setting them to full soft to better facilitate this.

They came pre-assembled and weren't touched. That being said, they've been on my buddy's truck for a few months now and I don't think they settled much at all. For reference, he's running 352 springs with steel skids, dual batteries, aluminum full bumper, and a winch. In the rear his truck probably settled 1/2" with the initial springs (701V's), since then he has upgraded to 749V's with almost no settling.

I know he played around with them a bit, but started from the Prado setting. I believe he went 2 clicks stiffer on both compressions. As of yet, he makes no adjustments for off-road driving

Get as much caster as you can (3-4 or more is great), everything else to factory

Thank you for your response!

We will def find the mounting locations before installing the strut, that is a great tip! Would it be possible to get a pic of where the resi's are mounted front and rear?

Appreciate the help!

Hi There, were you able to get the pics? We are ready to mount the fronts.

The way those fronts resi's are installed, they're extremely likely to get hit with the UCA on full up travel. It's not recommended to be mounted there for that reason, plus you're limiting/blocking access to adjust the rebound adjuster on the top of the strut.

The resi needs to be forward or rearward of the strut tower, out of the way of all moving parts (like the UCA's) and the tires that can turn in towards it.

https://exitoffroad.com/wp-content/u...ting-Guide.pdf

I suggest you do a full suspension travel test and check it out. IF that resi gets loose, you could destroy it, and the hose, and if that happens, you'll need a full dismantle of them to clean and replace the oil and parts that got damaged.

Thanks for that info Mike, I'll pass it along to the owner of the truck!

Here is mine on 2017 TRD Pro

Damping control settings are awesome, Settings are preferred how you like your ride quality to be. I'm 4+ clicks Positive and love it there. about 400+ miles on this suspension now ( went snow wheeling and mild off-road ) not a single issue in rubbing

I really like your front resi mounting position. Did you use existing holes or did you have to drill holes in the frame? How about the rears? from what I can tell, those are not pre-existing holes.

Appreciate you sending pics!
