QA1 2" drop spindles offer an easy, bolt-in solution to lower the front of your 2007 to 2018 Silverado or Sierra 1500. These spindles are compatible with both 2WD and 4WD applications in all cab configurations. The factory control arm construction will need to be determined to know which spindle fits your truck. These trucks came with either cast steel, aluminum, or stamped steel control arms. Verify your control arm construction before purchasing.
