Upgrading the suspension on my 2025 Toyota Tacoma TRD Off-Road completely changed how the truck performs off-road, but after installing my King 2.5 Lift Kit, I quickly realized the stock upper control arms would become a limiting factor. After some research and considering how aggressively I planned to use the truck, I decided to upgrade to the Dobinsons Billet Upper Control Arms (UCAs).
So far, I’ve been extremely happy with them. They’ve completely transformed the confidence I have in the front suspension off-road and made me feel much better about really pushing the truck hard. On top of that, they also ended up becoming one of my favorite visual upgrades on the truck, which honestly surprised me.

Why Upgrade Your Upper Control Arms?
A lot of people upgrading suspension on their Tacoma eventually run into the same issue: the stock upper control arms can only do so much once you start increasing suspension travel and lifting the truck.
When I installed the Kings, I knew the stock UCAs weren’t really going to work long term. With a larger suspension setup, the stock arms can start limiting articulation and even rub against components below under certain conditions. I also wanted to make sure I was getting the full benefit out of the suspension instead of bottlenecking the setup with factory parts.
My truck gets used aggressively off-road. I’m not just driving forest service roads at slow speeds. The truck sees rough terrain, high-speed dirt roads, washboards, rocky trails, and occasional jumps. Because of that, I wanted a setup that was strong enough to withstand abuse while still allowing the suspension to move freely and perform as it was designed to. Another big reason I chose these UCAs is the fact that they’re adjustable. I liked knowing that if I ever needed to make alignment changes or fine-tune the setup later on, I’d have the flexibility rather than being locked into a fixed design.
First Impressions & Build Quality
The first thing I noticed after opening the box was just how much more substantial these felt compared to the stock upper control arms. The factory arms feel relatively lightweight and simple, while the Dobinsons arms immediately feel much heavier-duty and confidence-inspiring.
At first, I honestly wasn’t sure how I felt about the finish color. I normally prefer more neutral suspension colors like black or dark blue, so I wasn’t convinced these would fit the look of my truck. But after getting them installed and taking photos of the suspension over time, they’ve really grown on me.
Now I actually love how much they stand out. They give the front suspension a much more aggressive and premium look, especially in photos. When you look through the wheel well now, the UCAs instantly catch your attention and make the suspension setup feel much more complete. The machining and overall quality also look excellent in person. Everything feels extremely solid and overbuilt in the best way possible. They honestly feel almost indestructible compared to stock.
Install Experience
One thing I want to mention is that I’m definitely not a mechanic by any means. Before this truck, I had very limited suspension experience, so I think it’s important to mention that this install was still very doable for someone willing to learn.
The biggest thing to note (at the time) is that the Dobinsons Billet Upper Control Arms did come with ball joints already installed. That meant I had to press the factory ball joints out of the stock arms and into the new ones. This was probably the most tedious part of the entire process. Using the press was a little intimidating at first, especially since I had never done it before, but with the right tools and a little patience, it proved very manageable. However, they recently updated them, and they now come ready to install without extra steps.
Outside of that, the install itself was fairly straightforward. Everything fit properly, and there were no major surprises along the way. Looking back, doing the install myself was actually a great learning experience because it helped me understand how the front suspension works together.
One thing I would absolutely recommend after installing UCAs is getting an alignment done right away. Once you start changing suspension geometry and replacing front-end components, alignment becomes extremely important not only for drivability but also for preventing uneven tire wear over time. I recommend doing your UCAs with your suspension to save money and not have to do it twice.
Overall, if someone with minimal prior knowledge like me can install them at home, I genuinely think most Tacoma owners could handle this install with basic tools and enough patience.
On-Road Driving Feel
One thing I appreciate about these UCAs is that they don’t negatively affect the truck on the road at all. In fact, the truck still drives extremely well and feels very stable overall. That being said, upper control arms are not really the type of upgrade that completely transforms daily driving on their own. They’re more about improving suspension geometry, articulation, durability, and overall front-end performance once you start modifying the truck.
With that said, the front end does feel very controlled and confidence-inspiring now. Hitting potholes, rough pavement, or uneven roads doesn’t upset the truck at all, and the steering still feels predictable and stable at highway speeds.
I also think the truck simply feels more capable overall now. Knowing the front suspension has stronger components underneath gives me a lot more confidence when driving aggressively or hitting rough terrain unexpectedly. And honestly, they turn a lot of heads, too. People notice them immediately when looking at the truck.
Off-Road Performance
This is where the UCAs really shine. Once you start driving off-road aggressively and actually using the suspension, the difference becomes much more noticeable. The front end feels much freer now, and I’m able to use the full capability of the Kings without worrying that the stock upper control arms will become a limiting factor.
At higher speeds through rough terrain, the front end feels extremely planted and controlled. Washboards, uneven dirt roads, and repeated hits feel much smoother and more predictable than before. The suspension cycles much more naturally, and the truck feels more composed overall.
I’ve also noticed a big improvement in articulation at slower speeds. When flexing over rough trails or uneven terrain, the suspension moves freely without the rubbing or binding issues that can occur with stock UCAs on lifted trucks.
Durability is another area where these really stand out to me. The arms feel incredibly beefy in person, and after putting the truck through some pretty aggressive off-road driving, I’ve never once questioned whether they could handle the abuse. They genuinely feel like one of the strongest components on the truck.
A lot of my friends who have seen the setup in person have already started wanting aftermarket UCAs for their own builds after seeing how substantial these are compared to stock.
Alignment & Things To Be Aware Of
One thing I’m still dialing in with my setup is alignment. Because the truck sees aggressive off-road use fairly regularly, I’ve noticed uneven tire wear over time due to alignment changes. This isn’t necessarily a Dobinsons-specific issue, but more of something that can happen on lifted Tacomas driven hard off-road. Once you start increasing suspension travel and pushing the truck aggressively, alignment becomes much more important than it is on a stock setup.
I’m currently looking into alignment cam gussets to help keep everything locked in place over the long term and prevent alignment changes after hard off-road use. It’s just something to be aware of when building a Tacoma that actually sees aggressive driving. Suspension upgrades are rarely just one part. You start to realize how everything works together once you begin modifying the truck more extensively.
Are They Worth It?
In my opinion, yes, absolutely. If you’re keeping your Tacoma mostly stock or only doing very light off-roading, you probably don’t need aftermarket UCAs. But once you start lifting the truck, increasing suspension travel, or driving aggressively off-road, upgraded upper control arms become much more important.
For my setup, I honestly see these as a must-have upgrade alongside the Kings. They allow the suspension to fully do its job and give the truck much better articulation, strength, and overall capability off-road. I also really appreciate the adjustability and long-term durability these offer. They feel like a component I’ll never have to worry about. In terms of performance, strength, adjustability, and overall quality, I definitely think they’re worth the money.
Final Thoughts
After spending time with these UCAs, I can confidently say they’ve become one of my favorite suspension upgrades on the truck. They completely transformed my confidence in the front suspension, especially during aggressive off-road driving, and they allow the Kings to perform as intended. On top of that, they look incredible and photograph extremely well, which has honestly become one of my favorite unexpected parts of the upgrade. Most importantly, they’ve held up extremely well to the kind of driving I built this truck for.
If you’re planning to properly lift your 4th Gen Tacoma and actually use it off-road, I genuinely think a quality set of UCAs like these is one of the best upgrades you can make.
