A spindle-based Chevy C1500 front lowering kit uses drop spindles paired with coil springs to achieve a 4-inch drop. It's one of the most proven methods and has been used on C1500s for decades.
On the other hand, a control arm-based setup uses new lower control arms with the factory spring, which works especially well for 2–3 inch drops without the wheel clearance concerns that can come with spindles on certain builds.
The rear portion of a 4/6 Chevy C1500 drop kit uses a flip kit, where the rear axle is moved from beneath the leaf spring to on top of it for a 6-inch drop. Because of how far the truck comes down, you'll also need to C-notch your frame for suspension travel.
Yes, it comes with new ball joints and urethane bushings assembled into the arms. That means your installation goes smoother because everything is prepped and ready to bolt on.
The upper control arms help you nail a clean alignment after the drop and give the front end a more finished look under the hood. It's a worthwhile upgrade if you're already doing the full job and want the geometry to be spot-on from every angle.
Yes, shock extenders are required on the more aggressive drops to keep your shocks operating properly after the rear axle has been repositioned. We include them in the kit along with all the necessary hardware.
It really comes down to how low you want to go and how you use the truck. The 2/4 or 3/4 Chevy C1500 lowering kit gives you a noticeable drop that still works well as an everyday driver, while the 4/6 is best suited for show builds.
