RTZ Chevrolet Silverado GMC Sierra 1500 88-98 5/7 Lowering Kit – 5" Front Drop Spindles & Coil Springs + 7" Rear Flip Kit + DoestchTech Premium Nitro Shocks (1988–1998 2WD V6)
The 1988–1998 Chevrolet Silverado and GMC Sierra 1500 is a different generation truck with a different suspension architecture, and it deserves a lowering kit built specifically for it. The RTZ 5/7 lowering kit for the 88–98 Silverado and Sierra 1500 2WD V6 drops the front 5 inches and the rear 7 inches using components engineered for this generation's specific suspension geometry. The complete package includes ductile iron 2-inch drop spindles, load-tested 3-inch front lowering coil springs, a rear axle flip kit, a pair of shackles, a frame notch kit, and a full set of DoestchTech Premium Nitrogen Gas Charged Slammer Shocks. If you're looking to buy an 88–98 Silverado 5/7 lowering kit with shocks online, this is the generation-specific kit built to go as low as this platform allows.
The front system pairs 2-inch ductile iron spindles with 3-inch load-tested coil springs for the full 5-inch front drop, keeping the 88–98 front suspension geometry correct at the lower ride height. At the rear, the axle flip kit repositions the axle above the leaf springs for the 7-inch drop, with shackles and a frame notch kit handling the clearance and geometry demands of running this configuration on the older body-style truck. DoestchTech Premium nitro slammer shocks complete the kit with damping tuned for a lowered stance.
