Take Your Tacoma’s Suspension to the Next Level
Upgrade your Toyota Tacoma’s suspension with CORE 4X4 Upper Control Arms, engineered to correct caster loss, improve clearance, and enhance suspension travel. Whether you're tackling extreme off-road trails or refining your daily driving experience, these premium control arms ensure maximum stability, handling precision, and durability for lifted and leveled vehicles.
What’s Included?
- Upper Control Arms (T-TAC-05-UCA2)
Key Features Benefits
- Optimized Caster for Lifted Vehicles – Welded ball joint cups are angled to restore lost caster, ensuring improved steering geometry and better handling.
- Superior Coilover Clearance Down Travel – Offset-welded bushings provide increased clearance, preventing interference with coilovers and allowing greater suspension articulation.
- Heavy-Duty ½” Plate Steel Construction – Built for maximum strength and durability, ensuring long-term performance in extreme off-road conditions.
- Greaseable Polyurethane Bushings – Equipped with 90-degree grease fittings, allowing for easy maintenance and increased longevity.
Engineered for Maximum Performance
When lifting a Toyota Tacoma, the spindle can shift, leading to rapid caster loss and poor handling. Factory control arms cause severe ball joint angles, resulting in premature wear and failure. The CORE 4X4 Upper Control Arms solve these issues by correcting alignment, improving coilover clearance, and reducing suspension stress. With precision-welded bushings and ball joint cups, these arms allow for smoother travel, enhanced durability, and maximum down travel for off-road performance.
Two-Stage Powder Coating
Each control arm undergoes a two-stage powder coating process for superior protection and longevity. A zinc primer base coat provides exceptional corrosion resistance, while a durable topcoat, available in 10 custom colors, adds a rugged yet stylish finish.
Fitment
This kit is designed to fit the following vehicles:
Toyota Tacoma (2005–2023) – 6 Lug
Conclusion
The CORE 4X4 Upper Control Arms are the ultimate upgrade for Toyota and Lexus off-road enthusiasts who demand improved alignment, better suspension travel, and extreme durability. With precision-engineered geometry, race-proven materials, and superior craftsmanship, these arms enhance both on-road comfort and off-road capability. Upgrade today and conquer any terrain with confidence!

Select your lift size in Step 1 — the kit ships with the correct geometry for that height. If you’re running a non-standard setup, call us before ordering and we’ll confirm compatibility.
Death wobble is a geometry problem, not just worn parts. Cruise Series corrects caster angle and eliminates the flex points that let shimmy start. Replacing one part at a time delays the fix — this replaces the geometry.
Yes, if you’ve done a lift kit before. Full-day project. Watch the complete JT install walkthrough on our YouTube channel — most owners wrap it in a day. Any off-road shop can run it if you’d rather have it done.
Any non-wear component fails — we replace it. No mileage cap. No maintenance intervals to track. No fine print about voiding if you miss a service. Lifetime means lifetime.
Teraflex’s lifetime warranty voids if you miss a maintenance interval. MetalCloak’s actual parts warranty is 12 months — their “lifetime” language refers to their service program. No conditions here.

Beefy parts made and painted well, very fair pricing for what you get, and fantastic customer service to boot. Easily my favorite place to get suspension parts.

I met a couple of the Core 4x4 guys at the Salt Lake Offroad Expo and decided to try them out after noticing one of my control arm bushings was disintegrated. I called to discuss parts on Thursday and I was leaving for a trip on Saturday. These guys built my control arms and had them ready to be picked up Friday, 24 hours later. The parts seem to be great quality and they charged me nothing extra to have them painted. These guys were extremely helpful and without them my trip probably would have been cancelled. looking forward to testing out the arms on my next trip to Moab.

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me.
As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a
Difference from the cheap oem rear control arms to these and the pan hard bar.
Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop!
Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.

I don’t write reviews often, but Core 4x4 absolutely earned this one.
I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts.
That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed.
The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots.
Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right.
If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.
