 Tubular control arms for coilover applications using
Negative Roll Geometry.
  The following tubular control arms will only fit a tall GM spindle measuring 8-15/16 inches tall across the ball joint bosses. This spindle is required in conjunction with our Negative Roll upper control arm in order to generate negative camber gain during cornering. The new geometry keeps the tire contact patch flatter on the pavement.

Note: This spindle will not work with stock upper control arms.

List of spindles that  will work.

Global West Negative Roll arms will not work with Stock spindles 7 inches tall. ( shown to the right)

They will also not work with ATS spindles or 2 inch dropped spindles.

(Negative Roll Systems)Featuring the New Generation II upper control arms.

Using tall GM disc brake spindles with our upper control arms will give you the following advantages:

Benefits and Features:

  • Improved tire life through new suspension geometry.
  • dramatic handling gains
  • 1-inch lower ride height without loosing suspension travel.
    (Spindle provides a 1-inch drop with this conversion).
  • No frame modifications.
  • Will not interfere with exhaust or steering column
  • Uses normal alignment shim pack
  • Has additional caster built into the upper arms.
  • Improved camber curve for handling.
    (True Negative Roll System)
  • Dedicated offset upper control arm shafts are used.
  • CNC machined components.
  • Ball joint angles are corrected to accommodate new geometry.
  • Round tube design provides superior strength.
  • Load carrier upper ball joints offering increased strength over original stock 4 bolt.
  • Allows 11 inch, 12 inch, 13 inch or  CAT5 disc brake upgrades .
  • Cross bars  provide additional strength during brake and cornering loads.
  • Positive bump stop eliminate possible over travel of ball joints.
  • Jig fitted and heliarc welded
  • Stock spring maybe used if desired.
  • Powder coat finish
  • Control arm are shipped pre-assembled with  DEL-A-LUM Bushings or polyurethane.
  • Control arms have a warranty

  1. Part # CNR-42A --$704.88 per pair  upper control arms for tall spindle conversion . The arms are powder coated black and are shipped pre-assembled with offset billet cross shafts, Del-a-lum bushings, bump stops, and ball joints. New alignment specifications are also included.
     
  2. Part # CNR-42AP--- $608.11 per pair upper control arms for the tall spindle conversion. The arms are powder coated black and are shipped pre-assembled with offset billet cross shafts, polyurethane bushings, bump stops, and ball joints. New alignment specifications are also included.  

Important: Tall disc brake spindles require using a CNR-42A upper arm kits
Two outer tie rods ends are also required for the conversion because of a taper change.
Use part #3007 for 1964-70 (1 kit required) $64.47
Use part #3008 for 1971-72 (1 kit required) $69.84

If you are going to use your stock lower control arm, you will also require a pair of special machined lower ball joints part #2005 ($107.48) because the new spindle has a different taper. However if you purchase a tubular lower arm for the conversion, the correct lower ball joint is all ready installed.

Tubular Lower Control Arms for 64-72 A-body coilover application.

Global West offers 2 different tubular lower control arms for  coilover applications using tall spindles. Each control arm provides maximum strength and durability. Built out of 1-5/8 roll cage tubing these control arms are stronger then stock and can handle the stresses incurred during high cornering loads and today's aggressive tire/wheel packages.

  • No special ball joints are required for later servicing.

  • A unique rotating spring mount is used which allows a perfect spring index every time.

  • A special sway bar end link is furnished with each control arm.

Tech Tip: You should always check the factory lower arm at the ball joint location for cracks and tears. Over the years it is not uncommon to see damage in this area.
