Built for Strength, Silence, and Serious Suspension Travel
If you're running a Tacoma and thinking about a suspension upgrade, this one’s for you. Our 4130 Upper Control Arms were made to solve the exact issues we kept running into ourselves — squeaky bushings, joints that need constant attention, and geometry that gets thrown off the second you add a lift.
These arms are designed specifically for 2005–2023 Toyota Tacomas (2WD or 4WD), and they’re built to handle it all — daily commutes, overlanding, rock crawling, and wide-open desert runs. If that sounds like your kind of driving, the new 4130 UCAs are for you.







SilentSpin™ Bushings – No Grease. No Squeaks.
Let’s be real — nobody wants to deal with squeaky bushings or messy grease fittings. That’s why we developed our SilentSpin™ hybrid bushings. They’re maintenance-free, fully sealed, and totally silent. Rain, dust, mud, daily driving — doesn’t matter. These stay quiet and responsive the whole time.


Pro 4 Ball Joints – Strength Meets Style
Every arm comes preloaded with our Pro 4 heavy-duty ball joints. You’ll get up to 38° of articulation and strength that holds up against hard side loads. They’re fully sealed, so you don’t have to worry about dirt getting in — and we added anodized caps to finish it off clean.
Designed for Lifted Tacomas
Running a lift? No problem. These arms correct your suspension geometry so your alignment stays dialed — even with 0–3” of lift. You’ll also pick up about an inch more down travel compared to stock, which makes a huge difference with aftermarket coilovers from King, Fox, Icon, and more.
