Dobinson MRR vs King 2.5's

My truck came with a dealer installed leveling kit and now that I've added some weight to the truck, (namely a canopy) the rear is starting to sag below the front. There might be an addition of a small off-road camper in the future as well, so I need to address the suspension.

I'd like to get rid of the leveling kit and install a mild lift kit, something like 2/1 and I've been looking at the Dobinsons MRR and the King 2.5's.

Does anyone have experience with both? Is one known to be more durable than the the other? The Tundra is more of a daily driver so having to rebuild the shocks often would be less than ideal.

I'd love to hear what you guys think! Thanks in advance!

 

Both are high end and will require rebuilds with long term use. Kings dominate in ease and availability of rebuilding. Also, king sells shims and aftermarket pistons can be found to easily revalve the shocks to get them perfect for your setup.
Ride is valving dependent. Kings all the way.

 

It seems like the Dobinsons might be more easily tuned with the variety of spring rates you have to choose from?

 

Springs just one component to tuning. Accutune could custom tune kings with valving, piston, and spring rate

 

Springs are universal. Dobinson, King, Eibach, etc. all do the same thing. One supplier may recommend one or two specific springs for their hardware, but you can swap any spring to any other shock.

I forget what all the Dobinson names mean, but the MRR I thought had three external adjustments of low and high speed compression and rebound? Where as the fanciest Kings only have one compression adjuster. I would probably base my decision on that mostly. As for rebuild ability, they're arguably the same though the Kings are certainly more readily available but if you consult with whoever is rebuilding the shocks before pulling them then they could reach out to Dobinson to get the parts, so I wouldn't worry about that too much.

Personally I would try the Dobinsons, people seem to like them and their external adjustments supposedly have more range of adjustment than Kings. I have Kings on my Tundra, and while I'm more than happy with them I don't think they're anything special so I'd be willing to try the Dobinsons. I don't think you can go wrong with either.

 

Would there be any issues upgrading the rear suspension first and doing the front at a later date?

Looks like we're getting a trailer sooner, rather than later, and I'm concerned with the factory OR springs and shocks handing the extra weight from the canopy, sliders, and the ~400lb tongue weight of the trailer.

 

Nope, people upgrade one end then the other all the time.

 

Good to know!

After looking into the two kits a bit more, it looks like the Dobinsons have a minimum of a 2" lift for both the front and rear, where as the Kings are adjustable from 0"-2". If that's the case, is an adjustable rear panhard bar automatically necessary for the Dobinsons? I'd rather not go down the route of upgrading anything other than the shocks and springs.

At most I would want 2" on the front with a slight rake at the back, so when I was towing the truck would sit more or less level. Would 2" in the front and 1" in the back more or less be level, or would that give a slight rake?

 

I have Kings 3.0 on the Tundra and Dobinsons Mrr on my son GX
They are both good shocks and as long you keep them clean they should last 80 K s if street is your main riding
Tundra hybrid with a RCI covert bumper I adjusted the Kings to the minimum and I got 1.1/2” lift
