Tired of prematurely wearing out front tires on your lowered or lifted 2WD F-150? Looking for improved handling and precise alignment control? 

Stifflers’ all-new 1997–2004 F-150 Adjustable Front Upper Control Arms deliver the solution. These adjustable control arms restore full control over front-end alignment on both Lowered & Lifted 2WD trucks—something factory upper control arms simply can’t achieve.

With a full range of caster/camber adjustability, Stifflers Upper Control Arms allow you to achieve factory alignment specifications, reducing tire wear while significantly improving handling and stability.

L² Technology – One Control Arm Set, Two Applications
Our innovative L² Technology allows a single control arm set to work on both lowered and lifted 2WD trucks. We have replaced the traditional ball joint with a configurable mono-ball assembly. One orientation is optimized for lowered trucks; reverse the mono-ball assembly, and the same set of control arms are ready for lifted applications.

L² Technology ensures proper geometry and performance regardless of ride height—simply configure the arms and to match your setup, just that easy!

Application Ranges

• Lowered - Ride Height from 14.5” to 18”  
• Lifted - Ride Height from 18” to 21”
