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

If you drive a 2011–2025 Silverado or Sierra 2500HD (2WD or 4WD) and you're 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 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 shocks like King, Fox, Icon, and more.

  • SilentSpin™ bushings — no squeaks or maintenance
  • Pro 4 ball joints with sealed dust caps
  • Rebuildable, USA-made construction
  • Precision-welded 4130 chromoly tubing
  • Shipped preassembled for faster installs

Does the job!!
Size: 14 Pcs, Color: Black
I bought this knife block set for my son for his first apartment and it has everything you need to start out. It does not take up much space. You can set it up on the corner of the counter. I would purchase this again. Very satisfied with the quality of the product.

Okay for the price
Size: 6 Pcs, Color: Stainless Steel
I looked a long time for a quality looking set for a budget price. I'm thankful that this is an option for the price range. Especially if you are on a budget, this is a good option. I know for the budget, you won't get the top-tier quality. However, when I got it, I wasn't too impressed by the quality. Though I'm thankful for the price, I felt this looked a little too cheap. The block was also far too flimsy. I was worried about removing and replacing the knives because the block "frayed" quite a bit. There were "crumbs" of block over the top that fell off the knife after you pulled it out. So I was very worried about touching the knife at all because I was worried about scratching or damaging the knives themselves. The knives themselves, though, I wasn't too worried about. They were the exact style I was looking for minus the color. I was looked for a more black or black-wash stainless steel like the ones I have now. I returned it the next day so I didn't try it out or take pictures. In the future, though, I'm now more willing to pay more for better quality.

This knife set offers great value for the price
Size: 6 Pcs, Color: Stainless Steel
I recently purchased this knife set, and overall, it has been a solid addition to my kitchen. Right out of the box, the knives felt well-balanced and comfortable to hold, which made a noticeable difference during meal prep. The handles provide a secure grip, even when my hands are slightly wet, and the weight distribution gives a sense of control that’s especially helpful for more precise cuts. In terms of performance, the blades are impressively sharp and handle a variety of tasks with ease—from slicing vegetables to cutting through tougher meats. I’ve used them regularly for a few weeks now, and they’ve maintained their edge better than I expected. That said, like most knives, they do benefit from occasional honing to keep them at peak performance. The set itself is versatile, covering all the essentials you’d need in a typical kitchen. The included block (if applicable) keeps everything organized and easily accessible, while also adding a clean, modern look to the countertop. One minor drawback is that the knives require careful hand washing and drying to prevent any potential rusting or wear over time. They’re not the kind of set you’d want to toss into the dishwasher if you want them to last. Overall, this knife set offers great value for the price. It’s a reliable option for both everyday cooking and more involved meal prep, especially for home cooks looking to upgrade their kitchen tools without overspending.

Affordable knives, horrible knife block
Size: 14 Pcs, Color: Red, Size: 14 Pcs, Color: Red
Knives are sharp and aren’t super rust resistant, but they get the job done. The knife block however, is horrible. It wasn’t sanded down or polished, so wood shavings can get into the grooves of the knife whenever you insert or take out the knives from the block.
