Product Overview
RTZ Chevrolet Silverado GMC Sierra 1500 88-98 V8 5/7 Lowering Kit – 5" Front Drop Spindles & Coil Springs + 7" Rear Flip Kit + DoestchTech Premium Nitro Shocks (1988–1998 2WD V8)
The V8-powered 1988–1998 Chevrolet Silverado and GMC Sierra 1500 carries more weight up front than its V6 counterpart, which is exactly why this kit exists separately. The RTZ 5/7 lowering kit for the 88–98 Silverado and Sierra 1500 2WD V8 is engineered specifically for the heavier V8 front end, dropping it 5 inches at the front and 7 inches at the rear with components built to handle the weight and geometry of this drivetrain. 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 V8 5/7 lowering kit online, this is the generation-specific, engine-specific kit built for maximum drop on the classic body style.
Up front, 2-inch ductile iron spindles pair with 3-inch load-tested coil springs to reach the full 5-inch front drop, keeping the 88–98 V8 front suspension geometry intact 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 providing the additional geometry adjustment and a frame notch kit handling the clearance demands. DoestchTech Premium nitro slammer shocks complete the package with damping tuned for a slammed V8 truck.

Fitment: Compatible with 1988–1998 Chevrolet GMC Silverado Sierra 1500 Pickup 2WD V8. Please check our other listings for V6 applications, the 4/6 configuration, and other drop heights.
Running a V8-specific lowering kit on your 88–98 Silverado is not just about fitting the right spindles; it is about ensuring that every component in the front suspension system is matched to the weight, geometry, and brake configuration of the V8 drivetrain. Using a V6 kit on a V8 truck introduces fitment and safety risks that a correctly spec'd kit eliminates from the start. Frame notching is required, 17-inch or larger wheels are mandatory, and professional installation by a qualified technician with proper equipment is strongly recommended. Please inspect all parts before beginning installation.

Frequently Asked Questions
- Why does the V8 5/7 kit exist separately from the V6 5/7 kit for the same years?
The 88–98 Silverado and Sierra V8 has a heavier front end and different front suspension geometry compared to the V6. The drop spindles and coil springs in this kit are engineered specifically for the V8 drivetrain; using a V6 kit on a V8 truck creates fitment and safety issues. - Is the front drop achieved by spindles alone or spindles plus springs?
Both. This kit uses 2-inch ductile iron drop spindles combined with 3-inch load-tested lowering coil springs to achieve the total 5-inch front drop. The spindle repositions the hub lower, while the spring reduces ride height further; together, they reach the 5-inch total. - What is the minimum wheel size required for this kit?
You must run 17-inch or larger rims. The spindle-based front drop uses larger brake components that require a minimum 17-inch wheel for proper clearance.
