Dobinsons IMS Struts and Shocks - Adjustable Height Monotubes - 5th Gen 4Runners
5 Attachment(s)
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 (long travel, no ETA yet, but probably some time in June 2020).
IMS Internal reservoir Monotube Shocks 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 Features

A proper strut coil compressor is required. Regular rental compressors can have teeth that hold the coil which are too thick, they won't work, as you probably won't be able to get the teeth out once the coil is on the strut. We offer the assembly of the front coilovers with new top mounts for an extra charge. 2 base options: 213mm - Base setting, same as OE, for coil seat height. Use this with lifted coil springs to let the coils do the lifting only 226mm - Taller setting, adds 1" of lift to whatever coil springs you're using. Use this setting with a 2" coil to produce 3" of lift, for example.

The purple would be the deal breaker for me.

Should expect the same life if not more actually. |

They do not have a set rebuild period like some other brands on the market. Without a reservoir and as many parts, there's less that can go wrong, especially with the quality of the components used. I can't put a date or mileage on it, but they should last a long time under standard use without needing anything. Now for someone that races with them or really goes hard offroad a lot, they'll be putting more heat thru them, so they might require a service sooner than other guys. |
Progressive or digressive valving?

Patient for what I don't need a lift already got one. Just saying I don't think most (yes speaking for everyone here) wants bright colors all over. But then could just be me. |

Pretend the rings are black...

Pretending real hard and it looks good.
Silver/chrome can get by too. |
Is the pricing for the shocks only? Which coils work with the fronts? I’m guessing any of your rear coils will be fine.

I was looking the MRRs but this price point is a little nicer and they still sound great!
Also, I personally don't mind the purple and teal. I've got a black truck so a little color is okay lol. These look like a great setup! |
@Crikeymike
two questionsfor you:
1) How much adjustability do you get with these? "Threaded bodies on struts allow for fine tuning of height and offer further improvements in cooling." 2) Do the Long Travel(IMS59-50574) add an additional 1" of lift? |
