Dobinsons IMS Struts and Shocks - Adjustable Height Monotubes - 200 Series (1 Viewer)

The cat got out of the bag recently about the new Dobinsons IMS shocks, so I'm starting this thread to give the details about these new struts and shocks from Dobinsons that are arriving in March 2020, and some versions coming after.

I guess IRMS sounded silly, and considering the already existing MRR (Monotube Remote Resi), a non-resi version didn't sound right either, this is the wording Dobinsons are going with.

In a nutshell, the IMS struts and shocks are almost the same as the MRR/MRA but with an IFP (Internal Floating Piston) inside the shock body with a small gas reservoir, and no external hose or reservoir. Same monotube body size, piston diameter, shaft thickness, and also the struts are height adjustable thanks to the fully threaded body. Super easy installation.
These do not have any valving adjustment.

From the manufacturer:
Dobinsons IMS Monotube Shock Absorbers are designed for next level performance over Twin Tube Shocks in those hot, harsh, demanding conditions. By utilising the Monotube design, Dobinsons IMS Shock Absorbers are able to resist fade far longer on corrugated roads, long or hard working 4WD trips, towing or racing conditions.

The larger 50 and 60mm high flow pistons reduce internal pressures, reduce the heat generated, transfer heat to the body for faster cooling and offer improved damping performance and vehicle control at higher shaft speeds on rough terrain and during big impacts. Threaded bodies on struts allow for fine tuning of height and offer further improvements in cooling.
The micro-polished, hard chromed and heat treated shock shaft, CNC aluminium high flow race inspired piston, and DOM seamless tubing body provides the ultimate in performance and off-road durability.

Composite piston wear bands and a race style 3-stage sealing system offer the lowest levels of friction whilst maintaining durability and longevity. Dobinsons team of engineers spend hundreds of hours of testing and tuning
the shim stacks and damping characteristics in each IMS Shock to ensure a balance of comfort, handling, vehicle control and offroad performance - Enjoy the ride

What about the MRA's?

There's a separate thread for those, but still waiting on the fronts. They aren't on the water heading for the USA yet.
