There are a ton of springs (and shock combos) out there so rather than just look at one spring, consider the type of driving you mostly do and what weight you carry, average and max, and choose the best balance.

891s may be stiff when the truck is unloaded. Air bags might be a good compromise in addition to rear springs for those extreme situations.

In all seriousness, like mentioned above, tons of good spring/shock options depending on how you want to set your truck up for the type of driving you do most often. Decide on your use case, choose a tire size, and spec accordingly.

Should I go 2890’s or just go straight to the 2891’s? I plan on keeping the cone and the Duro bumps.

The 300 lb number was my gear estimate. It’s probably between 200-300 actual. I should just go weigh it at the farm and see what’s really in it for weight.

I have 6112 Bilsteins up front and 5160 reservoir shocks in the rear. The shocks are awesome. I just need a little more spring in the rear when crawling over rocks and obstacles it feels like. Far as how I use it, I use it like a side by side with AC that I don’t have to trailer.

The 2906s were perfect until I added the steel t case and gas tank plates.

With that said, I would NEVER recommend these for a truck running stock weights. You'll end up pushing 5in of lift, which i've found to have a very pronounced effect on the handling dynamics of the truck. Right now I have ~3in of lift on the front, and I still have a solid rake to the truck. With a 4xinnovations plate bumper, full swingout (i.e. cook tray, dual 5gal jerry cans, hi-lift, and 33in mud tire), 10in sub, amp, recovery gear, 5 gallons of water, camping gear for four people, 55qt pelican cooler, I'm still .5-1in higher in the rear.

Now if you are running this heavy I highly recommend the 210v's, even over the OME 861s. The 210v's are progressive so you do end up getting a little better ride out of them when it is 'unloaded' (still with the plate bumper, spare, and sub). In the rocks they flex out well, zero complaints about that. If you're looking to get the most out of a permanently heavy setup I strongly recommend ditching the Bilstein 5100s and going with the Tokico Land Cruiser shocks. They have enough dampening for a 6000lb+ Land Cruiser so the won't struggle with a heavy 4runner. Not only that, they have about .5in shorter compressed length, and .5in longer extended length...also cheaper, I think I paid $43 per shock.

Just so you have all the information, my setup is: 210v's, Tokico LC shocks, Durobumps 5.25in bump stops (awesome upgrade), Eimkeith PCK, extended brake lines, relocated sway bar, poly upper control arm bushings, and new 98'+ OEM lower control arm bushings with Toytec skids. Overall, the rear of my truck is fairly dialed and works great without creaking, binding, or complaining. I've had a chance to demo 2.5in shocks for the rear, and while they are 'better', they don't add enough control to justify the price, the Tokico are good enough for 99% of what I do. Now the front is another story...after my re-gear and front locker install later this year I will be going to Radflo 2.5in coilovers. The 2.5in coilovers are a dramatic improvement over bilstein 5100s or Dobinson twin-tubes.
