Alright guys, I know a lot of you are still waiting on the external resi version of these (the MRA's), but they're just not done yet. But the new IMS are finally in stock and shipping now!!
IMS = Internal resi Monotube Shock.
The rears are also available separately: Dobinsons IMS59-60711 IFP Rear Shocks for Toyota Tundra 2007 to 2021 - https://exitoffroad.com/product/dobinsons-ims59-60711-ifp-rear-shocks-for-toyota-tundra-2007-2021/
And to build a full Dobinsons suspension kit with the IMS struts/shocks and all available parts, that kit builder page is here: https://exitoffroad.com/product/dob...spension-kit-for-2007-2021-double-cab-4x4-v8/
I'll try and predict some of your questions here, and add to this post as needed.
1. They use stock configuration coils (pigtail at the bottom, flat ground top), so they can be used with stock coils or Dobinsons coils, or a suitable replacement that uses the same configuration
2. If you already have Dobinsons twin tubes, you can replace just them with the IMS struts and shocks without needing anything else.
3. The fronts fit the 2008+ Sequoia. There are rear IMS coming for those too. I mention this because I know there's a lot of Tundra/Sequoia crossover on the forum here.
4. There is no set rebuilt period. If you ever had a problem with them, you'd do a rebuild at that time, which is generally just new seals and oil.
5. The fronts are to be set at the stock/standard coil seat height and then the coils do the lifting without adding additional preload. They can go up from there as needed to correct a lean or to compensate for added weight if needed to regain lost height.
6. I have to say it even though a lot of people understand already, but the rear shocks don't affect the lift height. Only changing the leaf springs or blocks, or add-a-leafs will affect the rear lift height.
Some words from Dobinsons:
Dobinsons IMS Monotube Shock Absorbers are designed for next level performance over Twin Tube Shocks in those hot, harsh, demanding conditions. By utilizing 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 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 aluminum 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 off-road performance – Enjoy the ride
