What's the equivalent of 6112's for Tacoma rear?

6112s provide a superior option at a great price point for the front of a Tacoma.
What is available in the $200-$300 range for the Tacoma rear?
Compared to 5100, larger diameter, more plush damping & better control, larger fluid capacity.
I know a lot of folks like the 5160, or 5125s but I'm not convinced that either provides much if any ride improvement, though all are better than the narrow stock OEM shocks.

 

As far as I can tell (without ever running them) the 5160 is in all respects the same as the 5100 with the addition of an external reservoir. The reservoir increases the oil capacity in order to keep it cool, since shock oil heats up over time as the shock works.
The 5100 has a much larger diameter than the narrow OEM shocks (49.8 mm for 5100s, vs 39.6mm for my 2017 TRD OR shocks) so they carry a lot more oil. Empirically, after my 90 minute drive home over a rough road, the OEM units used to feel very warm to the touch, and the new 5100s are still cool. I don't see how the 5160s would make any difference from the 5100s, unless for running for many hours on rough terrain, which I don't do these days. The 5100s in the rear have improved my ride a lot over the OEMs, seemingly more so after a while on the road. Still I quest for more...
8100s may be great, but at a grand apiece they are out of my budget.

 

5160s are nice

 

I was wondering this same thing. I’m lifted about 2.5” in the rear via spring packs. I have the B110 5100s in the rear now but they definitely fade quickly when pushing Offroad for a short period. I ordered 5160s for the ‘07+ tundras to try and get 5160s with a little more travel for my lift. The lower mounts were slightly too big to fit in the taco’s lower mounts. I was going to trim the sleeve or order new bushings for the lower mounts but then noticed the top stem for the Tundra shocks was much longer and “stepped”. I sent them back and am now scratching my head for a good replacement.

 

5100 is an emulsion shock, meaning the nitrogen charge is mixed in with the oil. With the 5160, a reservoir shock, the nitrogen charge is separated by a floating piston in the reservoir. So not only does a reservoir shock have more oil to keep the shock cooler it dampens bumps much better. Go to filthy motorsports for a more detailed explanation on YouTube.

 

Are the 5100's really emulsion shocks? I thought they were true monotubes with internal floating pistons that separate gas and oil.

 

Thanks Centurion. That's the first good explanation of the difference that reservoir shocks make. The Filthy Motorsports was a great video piece https://www.youtube.com/watch?v=rpEqmHknBJM. I am surprised how rapidly the temperatures change, and I never realized that they allowed the damping to operate with liquid and not a foaming emulsion.
I had some bad experiences with early reservoir shocks on a dual sport bike (BMW R100 GS) about 30 years ago; it was a drag to have a hose leak hot oil out on the trail.
I've been cursing the rear OEM shocks on the '17 TRD OR Tacoma for a couple of years, harshness on the washboards and hitting the bumpstops on dips even with an empty bed. I replaced them with 5100s about 6 weeks ago, which helped somewhat, but only partially. I was under the impression that the reservoirs on the 5160s would not alter the fluid dynamics or damping for the first hour or so.
The OEM rears on my '12 Gen 2 TRD OR I felt were better than the Gen 3 OEM.
I just ordered a pair of 5160s, and look forward to feeling what they can do. My ride home about 8 times a week is an hour of unpaved washboard and badly rutted and potholed ancient pavement taken at decent speed. I'm hoping that they will make a good difference.

 

None offered by Bilstein. Teraflex Falcon 2.25" shocks are in the price range, though I'm not sure if the rears are available outside the full F-R kit (they weren't as of May 2018): https://www.tacomaworld.com/threads...aflex-new-suspension-options-for-2016.531906/

 

Bilstein 5100s aren't emulsion shocks. There's an internal floating piston like most monotube shocks available for the Tacoma. Filthy Motorsports' video gives false information.
