Hey Guys and Gals,

I've compiled all of the shocks that Dobinsons make for the 80 Series on this one page on my website. Twin tube, IMS, and MRA, in 0-3", 4-5" and 6" lengths. 20 different options including the 2 steering damper options!! I'm not going to paste it all here, as it's subject to change over the years if any other options are added or edited. But for anyone looking, there's an option for all uses, and all possible lift heights.

Also, all shock lengths are listed next to each shock (xx/xx), extended/compressed, in millimeters. You can see how sometimes the twin tubes out perform the IMS and MRA's even in extended lengths. It was hard for me to bounce between pages to get someone the specs of each shock, so I went ahead and put it all on one page so it can be found easier and for my own benefit too.

And here's the main features of each of the 3 types of shocks.

MRR Monotube Remote Reservoir (discontinued)

  • These are the old and discontinued non-adjustable Monotube Remote Reservoir (MRR) shocks
  • Dobinsons replaced the MRR with the MRA (adjustable), starting in 2018
  • MRR were never stocked and regularly sold in the USA, only the newer MRA's were
  • Some people still use the MRR terminology, and the MRR logo is still in use in some cases, but the MRA name was created to show that it's an adjustable valve shock instead and the part number of the adjustables all start with "MRA" as well
  • These were great shocks, as a first generation of the MRR, but Dobinsons always wanted to be able to adjust the valving, so they evolved and changed a lot into the MRA shock lineup. The difference between MRR and MRA is night and day in terms of features and upgrades

Nice job Mike :cheers:
Can you add an entry in there (maybe under the MRA heading?) that clarifies the differences between MRA and MRR.

Sure thing, I'll do that.
