MRR or MRA — which one is this? This one is an MRR: a monotube shock with a remote reservoir, a separate canister holding extra oil and gas away from the shock body. More oil means more heat capacity, so the damping stays consistent on long corrugated roads instead of fading. The damping is set when the shock is built — bolt it on and it works, there is nothing to adjust. The Dobinsons family have since moved their own range away from the MRR and over to the MRA, which is the same monotube-and-reservoir design with three damping adjusters added. The MRR is still being manufactured by their business partner — the people who designed and built these shocks in the first place, and who helped the Dobinsons family develop their own shock range. That is who we buy ours from, so we can still supply the original MRR. Go MRR if you want the reservoir’s heat control in a set-and-forget shock. Go MRA if you tow, run varying loads, or want to dial compression and rebound in to suit the day. Not sure which you are looking at? The MRA has three adjuster knobs on it. The MRR has none.
