Dirt King Upper Arm Spacer Kit | Toyota Tacoma (2005-2023)

The Dirt King Upper Arm Spacer Kit adapts 1″ Probearing uniballs (P9AU16T) to the factory spindles, allowing you to build or upgrade uniball-equipped upper control arms while maintaining a precise fit. Machined from high-strength 17-4 stainless steel with a precision-fit taper, these spacers ensure reliable mating to the factory spindle and help maintain proper front suspension geometry. Designed specifically for Dirt King suspension systems, the spacer kit provides an efficient way to transition from stock ball joints to a uniball setup without unnecessary guesswork or modification.

This spacer kit is ideal for builders who want to increase suspension articulation and component durability while keeping a clean, bolt-on installation. All necessary hardware is included, and the design retains a strong and serviceable connection between the uniball and the spindle.

Installation

Installation involves removing the factory upper arm components and preparing the spindle for the uniball interface. The included stainless spacers are slid over the spindle and mated with the Probearing uniballs. Using the custom machined Grade-8 bolts and supplied hardware, secure the spacers and uniball to the spindle, ensuring proper alignment and torque to specification. Because this kit is intended for Dirt King suspension systems, double-check fitment and alignment before final torqueing. Professional installation and alignment check are recommended if you’re not familiar with suspension component swaps.
