INTRODUCTION 

The Cognito Ball Joint SM Series Upper Control Arm Kit is a direct replacement for the factory upper control arms 
(UCAs). The Cognito UCA kit will add performance due to a modified ball joint angle that eliminates travel limitations 
of the ball joint in leveled or lifted applications. The allowable droop travel is also improved with the design of these 
arms. Designed and made in the USA. 
 
 
 
 
 
 
 
 
 
 
 
 

REQUIREMENTS 

 

The service perch under the front UCA on the vehicle’s frame will 

require cutting. 

 

Proper shocks and shock lengths must be used, or damage to control arms, ball joints, and vehicle will occur. 

 

With taller than stock wheels and tires, trimming will still be required to the back bottom of the fender well 
area and the plastic valance under the front bumper. 

 

Installation requires a qualified mechanic. 

 

Follow the OE specifications when replacing or re-installing OE fasteners, retainers, and hardware specified in 
the OEM manual. 

 

Always wear safety glasses when using power tools. 

 

When a lift is required to perform the installation of these products and always ensure the vehicle is properly 
supported before attempting installation or serious injury may occur.
