Product Overview
RTZ Chevrolet Silverado GMC Sierra 1500 V8 5/7 Lowering Kit – 5" Front Drop Spindles & Coil Springs + 7" Rear Flip Kit + DoestchTech Premium Nitro Shocks (1999–2006 2WD V8)
If you've already decided the 4/6 drop isn't enough for your V8 Silverado or Sierra, the RTZ 5/7 lowering kit is the next step: one inch more of front drop and one inch more at the rear, with all the engineering behind it to make it work properly. Built specifically for the 1999–2006 Chevrolet Silverado and GMC Sierra 1500 2WD V8, this 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 a Silverado V8 5/7 lowering kit with shocks online, this is the maximum drop configuration available for the V8 application.
At the front, 2-inch ductile iron spindles are paired with 3-inch load-tested coil springs to achieve the full 5-inch front drop, keeping front suspension geometry correct while going lower than a standard 4/6 setup. The rear axle flip kit repositions the axle above the leaf springs for the 7-inch rear drop, with shackles and a frame notch kit included to handle everything the extra drop demands. DoestchTech nitro slammer shocks complete the kit and keep ride quality and handling dialed in at the lower stance.

Fitment: Compatible with 1999–2006 Chevrolet GMC Silverado Sierra 1500 Pickup 2WD V8. Please check our other listings for V6 applications and different drop heights.
Choosing the V8-specific 5/7 kit over the V6 version matters: the front suspension components are engineered for the weight and geometry of the V8 drivetrain, and using the correct engine-specific kit is what ensures proper fitment and safe installation at this drop level. With 5 inches of engineered front drop and 7 inches at the rear, this is a build for owners who are fully committed to a slammed stance on their V8 Silverado. 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
- What is the difference between the V8 5/7 kit and the V6 5/7 kit?
Both kits achieve the same 5-inch front and 7-inch rear drop, but the components are engineered specifically for each engine. The V8 kit is built for the heavier front end weight and suspension geometry of the V8 drivetrain; using the correct engine-specific kit is essential for proper fitment and safety. - Why does this kit include shackles when the V8 4/6 kit does not?
The additional rear drop height of the 5/7 configuration requires shackles alongside the axle flip kit to achieve the full 7 inches at the rear. The 4/6 kit reaches its 6-inch rear drop with the flip kit alone. - Is professional installation required for this kit?
Yes, strongly recommended. This kit requires frame notching for rear clearance and 17-inch or larger wheels. The combination of spindle drop, coil spring drop, axle flip, and frame modification makes professional installation by a qualified technician with proper equipment essential.
