Dirt King 4130 Upper Control Arms – Built to Solve Real Problems

If you drive a 2025+ 4Runner (2WD or 4WD) and ready for a suspension upgrade, these 4130 UCAs are for you. We made them to tackle the exact issues we kept running into ourselves—squeaky bushings, joints that need constant attention, and geometry thrown off as soon as you add a lift. Whether you’re daily driving, overlanding, rock crawling, or chasing desert trails, these UCAs handle it all.

These arms feature maintenance-free SilentSpin™ bushings that eliminate grease fittings and unwanted noise, along with heavy-duty Probearing Pro 4 ball joints for high articulation and superior strength. The ball joints are sealed to block out debris and finished with anodized caps. Built to maintain proper alignment from 0–3" of lift, these arms also add roughly an inch of down travel compared to stock, a must-have when paired with our shocks or other aftermarket coilovers like King, Fox, Icon, and more.

Works for Sherpa, and heavy rugs
This worked on my 2 Sherpa jackets and a heavy furred rug. I tested it on my old Sherpa jacket that had the furs pretty much flat after years. I used this on it which took about 3 hrs to do and it feels brand new. I was so shocked that I used it on my old rug that had about an inch length in fur. The fur was all tangled so it had little stalks sticking out. After about 6-7 hrs, the rug was straight up rejuvenated felt brand new. I’m was very pleased with this product. Now, the real question is it worth it? I’ll just tell my opinion from my experience and let you decide for yourself. The product itself feels sturdy with a wooden base. It’s around 6 and a half inches so not very big. (This is one of the reasons why the rug too so long.)The metal brushed was surprisingly durable. I was applying a good amount of force when combing my rug and there were no bending. For 14 dollars and some elbow grease, I got two new jackets and a rug. The brush didn’t break so I can just keep using this to maintain. In my books, I got my moneys worth.

Great for shoes
This brush works well for fluffing up the inside of those sheepskin clog shoes we all own.

It Works!
A small size but fits my hand and really does the job well. I have two sherpa blankets that the fibers are matted down from the dryer (should have air dryed) and this brush glides through the fibers, does require some effort but well worth it as I get instant results of the before and after. So far, brush is intact and handling the job, one larger and one smaller blanket to go and both sides. Very happy with purchase!

LL Bean slippers
Larger than it looks, but still small enough to fit into my LL Bean Wicked Good Slippers. Let's me comb out the shearling to keep it soft and pretty.

Good.
Works perfect to brush sheepskin. However it's a bit difficult to remove the fluff without hurting your fingers.
