Four inches of front drop and six inches at the rear give the old body style Silverado a clean, planted look that works as well on the street as it does at a show. This complete package includes ductile iron 2-inch drop spindles, load-tested 2-inch front lowering coil springs, a rear axle flip kit, a frame notch kit, and a full set of DoestchTech Premium Nitrogen Gas Charged Slammer Shocks everything needed to drop and drive your 88–98 Silverado or Sierra in one order.
The front drop system uses 2-inch ductile iron spindles paired with 2-inch load-tested coil springs, achieving the 4-inch total front drop while keeping the 88–98 generation's front suspension geometry intact. At the rear, the axle flip kit repositions the rear axle above the leaf springs for the full 6-inch drop, with a frame notch kit included for the clearance the configuration demands.
