Product information updated on 2021-08-25, Manufactured by MaxTrac Suspension - Part Number MXT:101520, 2014-18 Chevrolet Silverado 1500 Front Lowering Spindles - 2 inch Drop Height, Requires 18" Rims Or Larger - Fits 2Wd Only, Our forged aluminum 2 inch drop spindles are designed by taking an OEM spindle and raising the wheel mounting position up 2 inches. This allows the a-arms to keep the same angles as factory. We then forged the spindles in a T6082 aircraft grade aluminum for superior strength and durability. This keeps the weight down on the suspension and allows for larger heavier wheels to be mounted without changing any of the vehicles capabilitys. Our spindles are also simple to install and retain all factory hardware.
