Now available is our the 2″ drop performance spindle set up for 64-74GM A, F and X body muscle cars. These one-piece forged steel spindles are designed to work with GM A, F, X body cars. G-Compspindles are engineered for lower ride height, improved negative camber gain and positive caster gain, plus more adjustable alignment. They correspond with OEM parts and provide an overall 2″ drop in ride height. By modifying the ball joint location you improve the arc at which the upper control arm swings thus yielding a different camber curve. As the car leans into a turn, the new camber characteristics keep the tire contact patch at a maximum thus allowing higher cornering speeds through improved traction.
