Product Overview
RTZ Chevrolet Silverado GMC Sierra 1500 88-98 V8 4/6 Lowering Kit – 4" Front Drop Spindles & Coil Springs + 6" Rear Flip Kit + DoestchTech Premium Nitro Shocks (1988–1998 2WD V8)
Not every classic body style Silverado build needs to go as low as a 5/7 setup allows. For 1988–1998 Chevrolet Silverado and GMC Sierra 1500 2WD V8 owners who want a strong lowered stance with a more manageable installation, the RTZ 4/6 kit is the right call: four inches of front drop and six inches at the rear, all engineered specifically for the V8 drivetrain of this generation. 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.
The front system uses 2-inch ductile iron spindles paired with 2-inch load-tested coil spring components spec'd for the V8 front end weight and suspension geometry of the 88–98 generation. The spindle-and-spring combination achieves the 4-inch front drop while keeping steering feel and ride quality where it should be on a properly lowered truck. At the rear, the axle flip kit handles the 6-inch drop, and the included frame notch kit provides the clearance the configuration requires. DoestchTech Premium nitro slammer shocks complete the package.

- Pair of 2-inch ductile iron drop spindles front, V8 specific
- Front lowering 2-inch coil springs, load-tested
- Rear axle flip kit, 6-inch rear drop
- Frame notch kit required for full drop clearance

Fitment: Compatible with 1988–1998 Chevrolet GMC Silverado Sierra 1500 Pickup 2WD V8. Please check our other listings for the 5/7 configuration and V6 applications.
The 4/6 configuration on an 88–98 V8 Silverado gives you a stance that commands attention without requiring the extra rear modifications that come with going to 5/7. No shackles are needed; the drop is handled by the axle flip kit and frame notch alone, and the DoestchTech shocks keep the lowered truck composed on the road. If you want to go lower later, the 5/7 kit is available, but for a first-time lowering build on a classic V8 Silverado, the 4/6 is the proven starting point. 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
- Does the 4/6 V8 kit include shackles as the 5/7 V8 kit does?
No. The 4/6 configuration achieves its 6-inch rear drop using the axle flip kit and frame notch kit alone; shackles are not required at this drop height. Shackles are included in the 5/7 kit for the additional rear drop height it requires. - Is this kit the right choice if I want to lower my truck but stay closer to a daily driver setup?
Yes. The 4/6 configuration delivers a strong lowered stance while involving fewer rear modifications than the 5/7 kit. It is a practical choice for V8 Silverado owners who want a significant drop without committing to the maximum slam configuration. - Will V6 lowering components fit my V8 88–98 Silverado?
No. The V8 front suspension carries more weight and has different geometry than the V6. Using V6-specific spindles or springs on a V8 truck creates fitment and safety issues; always use the correct engine-specific kit for your application.
