This listing is for one pair of spindles. 
 
The RideTech spindle is a heavy duty forging that is approx. 1.75″ taller (ball joint to ball joint) than the OEM spindle.  This changes the angle of the upper control arm which induces negative camber gain to maximize tire contact patch during cornering.  It also offers a 2” pin drop which allows for the use of longer shocks creating more suspension travel.    Compatible with any brake kit that is designed to fit the stock disc brake spindle.
