Description
 

Our new billet CNC upper control arms were born out of our relentless R&D track testing program! These billet upper control arms achieve three main goals critical for track and high performance driving:

  • Adjustable camber for improvement in front end cornering traction and reduction of outer tire wear,
  • Reduced deflection for improved steering feel and precision, and
  • Optimized caster for maximum camber gain and increased steering weight and stability.

Camber is easily to adjust with two spherical rod ends. Camber can be increased for track days and reduced for street use to improve tire wear. Typical camber adjustment range is approximately -1 up to -3.5 degrees of negative camber, enough for any track application using street or race tires.

Due to the caster offset built into the CNC arms, we build in a maximum caster increase and there is no need to adjust caster. Increasing the amount of caster has several benefits, including improvement of steering effort and straight line stability, particularly at high speeds. Additionally, the more positive caster that is built into your suspension geometry, the more negative camber is gained as your wheels are turned. This allows for reduction in the amount of static negative camber required, thereby improving inner tire wear and braking performance.

Construction of our Ultimate Upper Control Arms is second to none. Key features are:

  • Made in USA CNC 6061-T6 billet arms exhibit incredible strength and durability under the most demanding conditions.
  • High quality chrome steel spherical rod ends for adjustment.
  • 7000 series aluminum jam nuts (every bit of weight reduction counts!)
  • OEM quality fully sealed no maintenance Japanese ball joint.
