Ball Joint Upper Control Arms (Gen 2) | 07-21 Tundra

Dirt King

Product Sku: DK-815991

  • $749.00


The Dirt King ball joint upper control arms are engineered to improve suspension geometry, enabling additional front lift when paired with Dirt King shocks. Lifting a vehicle with stock upper control arms compromises both the geometry and structural strength due to excessive articulation at the factory joints. The Dirt King arms address these issues with improved caster settings for enhanced handling and re-engineered pivot angles for increased articulation. The inner pivots feature Probearing SilentSpin Hybrid bushings, offering the ideal combination of a free-spinning inner sleeve, typical of poly bushings, with the maintenance-free and greaseless advantages of OE elastomer bushings. Additionally, the standard ball joints have been upgraded to heavy-duty Moog ball joints ensuring superior durability. All components of these upper control arms are rebuildable or replaceable, promoting long-term durability and ease of maintenance. These arms arrive preassembled with detailed instructions for a straightforward installation.

  • Wheel Travel: Additional 1” of down travel compared to stock
  • Amount of Lift: Allows for 0-3” of lift
  • Track Width: Stock
  • Maximum Backspacing: 4.75”
  • Minimum Rim Size: 17”

Wheel Travel / Lift
The Dirt King upper control arms must be paired with aftermarket coilover shocks to lift the vehicle. The Dirt King arms offer an additional 1” of down travel compared to the stock upper control arms. These arms are compatible with Dirt King, King, Fox, Bilstein, ADS and Icon coilovers. Do not install these upper control arms with coil spacers paired with extended length aftermarket shocks.

Easy install

Arrived ready for install. Just remove old arms and put these in. Was nice that I didn't have to press in bushings or anything. They came with new nut and pin for the balljoint too. Only part reused was the main bolt and nut. I normally wouldn't go for gold color but these arms look really good on my truck. Movement seems to be pretty smooth. NOTE: Dirt King has wrong torque printed in instructions. I contacted DK to confirm that the nut on the mounting bolt should be same as oem spec at like 172ftlb, not 85.

Solid and reliable

Major upgrade over my previous SPC ball joints (which should probably be reserved for mall crawlers in 37”+ tires) - these uca's are built really sturdy, shops won’t have to mess with their adjustments, and the ball joints are easily serviceable and replaceable without needing an alignment. Add to that, Colton’s excellent service and product knowledge, I’m very happy with this purchase!
