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

If you drive a 2007–2018 GM 1500 (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 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.

Why Go Dirt King?

  • 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

Upgrade Your GM 1500 With Confidence
Built and tested in the USA, these 4130 UCAs are engineered for the long haul—perfect for rigs that work hard on weekdays and explore even harder on weekends. It’s the last set of upper control arms you’ll ever need.

Specifications

  • Amount of Lift: Allows for 0–3” of lift
  • Track Width: Stock
  • Maximum Backspacing: 4.75”

Wheel Travel / Lift
The Dirt King upper control arms must be paired with aftermarket coilover shocks to lift the vehicle. These UCAs offer more usable down travel compared to stock arms. Compatible with Dirt King, King, Fox, Bilstein, ADS, Icon, Eibach, and other OEM replacement coilovers. Do not install with coil spacers paired with extended-length aftermarket shocks.

Trash
Model: 17785
Ordered 2/22/26, installed2/23/26, had a gritty sound immediately, and should've asked for a replacement then but was just happy to be mobile again, 3/29/26 left me sitting on the side of the road popping starter fuses over and over... not a decent part especially since im now realizing there is zero warranty... do yourself a favor, read the reviews before you buy and dont put money in this sellers pocket
