Dirt King Upper Control Arm Installation Mesa AZ — 4130 and Billet UCA Install
Dirt King Upper Control Arm Installation — Mesa, AZ
Upper control arms are the most popular Dirt King product — and one of the most important suspension upgrades you can make to a lifted truck. When your truck is lifted, factory UCAs place the ball joint in a compromised angle that accelerates ball joint wear, reduces shock travel, and negatively affects handling. Dirt King UCAs fix all of that.
Schmidty Racing Suspensions in Mesa, AZ provides professional Dirt King upper control arm installation for all supported vehicles across the Phoenix metro area.
Dirt King UCA Options — 4130 vs Billet
4130 Chromoly UCAs
Dirt King's 4130 chromoly upper control arms use high-strength chromoly steel tubing — the same material used in race car chassis construction. 4130 UCAs provide excellent strength-to-weight ratio, improved geometry correction, and sealed high-angle ball joints for extra lift and articulation.
The 4130 UCAs feature Dirt King's new maintenance-free Probearing SilentSpin bushings for quiet, smooth operation — no greasing required. Available for most supported platforms starting around $899.
Billet Machined UCAs
Dirt King's billet upper control arms are CNC machined from billet aluminum — providing a premium aesthetic alongside the performance benefits. The machined construction allows for tighter tolerances than welded tube arms and provides the most precise geometry correction available.
Billet UCAs are the choice for truck owners who want both maximum performance and premium appearance. Starting around $1,449.
Why UCAs Make Such a Big Difference
When you lift a truck, the factory upper control arm geometry was not designed for that height. The result:
- Ball joint angle compromise — factory ball joints are stressed at lifted heights, accelerating wear
- Caster loss — factory UCAs cause caster to go negative when lifted, affecting straight-line stability and steering return
- Reduced shock travel — factory UCAs limit how far the shock can extend, reducing available travel
- CV axle angle — improper UCA geometry increases CV axle angles, accelerating CV wear
Dirt King UCAs are engineered specifically for the lifted height of each vehicle — correcting all of these issues simultaneously with a single upgrade.
