I've run dobinsons in my troopy since I've owned it, have no complaints. Here's some quotes from my own build thread right after I put dobinsons in.
----------------------------------------------------------------------------------------
"I've been sold on Dobinson for awhile. Shackles, bushings and hardware seem to be nicer all around, and the fact their springs don't pop within a few months of install is nice too."
"Dobinsons on our Troopy too. We have been a dealer for a while....all our builds are getting their stuff. I've used OME for 25 years on my trucks so it was tough to change over to Dobinsons but glad we did. Absolutely on of the best places to deal with.....great customer service. Very very helpful and quick to take care of any issues."
"OME shocks are(were?) made by Monroe to OME/ARB standards. Thats your standard nitrocharger shocks. I believe they are made IN australia in a Monroe plant from all info I have found. As for the high end ARB BP51 bypass shocks, they say designed/made in house. Tenneco owns Monroe since 1977. As for Dobinsons, I don't know if they are made in house or outsourced to like Monroe/Gabriel. Their website and history says they have always been manufacturing and building shocks/suspensions.
They say this:
As Dobinsons Spring and Suspension have been manufacturing the highest quality springs and suspension components for over 60 years, they are no strangers to state of the art manufacturing processes. Dobinsons 4×4 shock absorbers are manufactured using the latest technology and are manufactured to TS16949 International Quality Assurance Systems. This includes double re-enforced robotic welding, friction welding, CNC Machined components and drop forging of high stress mounting components. Then state specifically about In House Dyno shock testing and In House Durability testing. SO, whether that means they outsource shocks have them built to their specs then IN HOUSE test them, or it's just bad wording on the website and they do design/manufacture/test all in house."

Soooo uhhhhhh yea there's a lot of words in favor of dobinsons, also just read earlier today (idk what thread) but 2 people were complaining about their OME heavy duty springs going flat much sooner than they would have liked. At the end of the day suspension is suspension, there's a bunch of reputable brands out there and the ride quality will probably be all around equally as bad for these old leaf sprung cruisers. One thing is
I'm not sure dobinsons sells 3-4in lift kits, do some digging and I'm sure you will find out if they do or dont
