Five inches of front drop and seven inches of rear drop, the RTZ 5/7 lowering kit for the 1999–2006 Chevrolet Silverado and GMC Sierra 1500 2WD V6 is built for owners who want to go lower than a standard 4/6 setup and have the handling to match. 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 5/7 lowering kit with shocks online, this is the full V6-specific slam kit built to take your truck as close to the ground as this configuration allows.
The front drop system pairs 2-inch ductile iron spindles with 3-inch load-tested lowering coil springs, combining spindle drop and spring drop for a total 5-inch front reduction that maintains smooth ride quality and proper front suspension geometry. At the rear, the axle flip kit repositions the rear axle above the leaf springs for the full 7 inch drop, with a pair of shackles and a frame notch kit included to handle the clearance demands of running this low. DoestchTech nitro slammer shocks complete the package and deliver the refined, sport-tuned damping you need on a slammed truck.

The 5/7 configuration pushes your Silverado or Sierra lower than the 4/6 kit an extra inch of front drop and an extra inch of rear drop that makes a visible difference in stance, especially when the truck is sitting still at a show or cruising a boulevard. The addition of shackles at the rear and the 3-inch coil springs up front are what separate this V6-specific kit from the V8 4/6 package. Frame notching is required, 17-inch or larger wheels are mandatory, and professional installation is a must. Please inspect all parts before beginning installation.

Frequently Asked Questions
- What is the difference between this 5/7 kit and the 4/6 V8 kit?
This kit is engineered for the 2WD V6 Silverado and Sierra and achieves a 5-inch front and 7-inch rear drop using 2-inch spindles combined with 3-inch coil springs up front, plus shackles at the rear going one inch lower front and rear compared to the V8 4/6 package. - Why are shackles included in this kit but not the 4/6 V8 version?
The 5/7 drop configuration requires shackles at the rear to achieve the additional rear drop height alongside the axle flip kit. They are specific to this drop level and engine application. - Does this kit require any modifications beyond frame notching?
Frame notching is the primary required modification for rear clearance. You must also run 17-inch or larger wheels due to the brake size associated with the spindle-based front drop. Professional installation is strongly recommended.
