Dobinsons IMS Tacoma Lift Kit Long-Term Review

A suspension lift is one of those mods that genuinely makes a difference in performance, whether you’re on the road or off the beaten path.

When searching for suspension, there were three criteria that I was looking for – performance, value, and support. After evaluating many different setups and companies, I ultimately landed on the Dobinsons IMS Lift Kit for my rig.

They weren’t initially on my list to evaluate, but after countless hours of “intense scientific research”, I decided to put it on my shortlist. While researching them, they seemed to have many positive reviews with fewer people split between love and hate compared to others.

Dobinsons claims that the IMS (Internal Monotube Shock) system has virtually zero shock fade in all terrains even under full load. Another unique feature at this price point is that they are fully rebuildable and can be revalved.

Now that I’ve been running this setup for about two years and more than 25,000 miles through all kinds of terrain, I’m here to provide my long-term review.

Note: This will fit the 2nd Gen Tacoma as well, but my experiences are solely with the 3rd Gen, double cab, short bed Tacoma.

My Setup

My setup has not changed since I initially purchased and installed it. Here’s how it is configured:

• Coil Color: Black (originally, I wanted red, but backorder was going to be possibly months, and I wanted it sooner)
• Front Struts: IMS59-50220
• Front Springs: C59-314 (2.0″ – stock front end)
• Rear Springs: L59-110-R (2.1″ – Light/Medium Constant Load)
• Rear Shocks: IMS59-50940 (standard travel)
• Sway Bar Relocation: SE59-524K (did this but not necessary)
• Rear Polyurethane Leaf Spring Bush: PB59-1101K
• Greasable Pin: SP59-060

With a lift like mine, you should also purchase aftermarket upper control arms for proper alignment. I chose to go with SPC UCAs. The shop that did the installation also recommended aftermarket bump stops, so I went ahead and got DuroBumps front and rear. These help protect your fenders from larger wheels and increased articulation.

Initial Impressions

Before I go into my initial impressions, I want to preface and say that I also upgraded my wheels and tires when I had my lift installed. I went up a size to 285/75R16, which is just shy of a 33″ tire.

As I pulled up to the shop, I was thrilled with how my truck looked. It was the perfect amount of lift and look that I was going for. However, as I got in and drove away, my first thought was how super stiff and bouncy the ride felt. This persisted for a couple of weeks (I work from home, so I don’t drive a lot).

After the first few weeks, though, the suspension settled and I was happy with where it ended up in terms of stiffness and ride quality.

On-Road

Since this is my daily driver and family hauler, it’s seen a good amount of on-road miles. The suspension is noticeably stiffer than stock but not to the point where it is jarring or unbearable. I’ve ridden in other lifted Tacoma’s where the ride was softer, but felt they had too much body roll and were “squishy” (for lack of better terms).

My setup has noticeably reduced body roll and that dreaded braking nose dive. I could not be happier with the on-road performance that this kit has provided.

Off-Road

Taking my rig off-road across different terrains and difficulties helped me appreciate this kit’s quality, dependability, and performance.

They do an excellent job of soaking up big bumps and dips, especially in slower and more technical sections. Over washboard and rocky roads, I feel that I have to either air down extra or go slower because the suspension sometimes feels jarring or too stiff. That said, it feels controlled and is not unbearable or a deal breaker.

Service & Support

We’ll start by discussing one of the downsides I discovered after purchasing and using this kit. For me, a big selling point was that it was fully rebuildable and can be revalved. Admittedly, I was also naïve to think that anyone who could do rebuilds for other shocks could service these as well. I was wrong.

One shop in my area is willing to service it, but outside of that, it would be a 2.5-hour drive to the next one. Since this rig is my daily driver, I don’t have the luxury of being able to send the shocks out to Dobinsons either.

So, my recommendation is to first reach out to shops in your area to see if they can service Dobinsins’ kits or be ready to send them out and have downtime with your truck.

As a company, I cannot say enough nice things about Dobinsons’ overall support. From purchasing questions to after-installation support, the team has been amazing to communicate with. They’re incredibly knowledgeable and have made my experience of owning this product a positive one.

Whether the communication has been over the phone or email, I always get to someone who knows what they are talking about. Plus, I get the sense that they genuinely care about the customer experience.

Final Thoughts

After having it for almost 2 years and 25,000 miles, I can say that I’m still very happy with it. The only downside for me was that my local 4×4 shop, where I typically get all my work done, does not service Dobinsons. However, that’s not a knock on the suspension.

Everything has held up well and has performed to my expectations. I genuinely feel like this kit has the best value, performance, and support; all of which were what I was looking for when lifting my rig.

If you’re looking for a great value suspension, I highly recommend this one. You can choose to get just a few pieces such as coils or shocks, or the entire kit. Not only does it perform well on-road, but it performs exceptionally well off-road. For most, it will be more than enough. Lastly, the customer support that I have received has been top-notch.

I hope this helps you in your journey to finding a suspension kit that meets your needs.
