Silverado/Sierra 1500 ZR2/AT4X PRELOAD Lift Kit (2.25" Lift Height)
Take the stance and capability of your Silverado ZR2 one step further with the Vector Engineering Preload Lift Kit—a complete front leveling solution designed to deliver additional lift while addressing one of the common weak points in the factory Silverado/Sierra 1500 suspension.
Building on our standard ZR2 Billet Leveling Kit, the Preload Kit adds precision-machined lower spring collars to achieve additional front lift while retaining the factory ZR2 suspension. The result is a more aggressive stance, increased clearance, and a purpose-built solution engineered specifically around the Silverado/Sierra ZR2/AT4X platform.
CNC-Machined 6061-T6 Billet Aluminum
Every billet component in the Preload Lift Kit—including the upper components and lower collars—is precision CNC-machined from 6061-T6 billet aluminum for an ideal combination of strength, durability, corrosion resistance, and low weight.
Each component is finished with a durable black anodized coating to protect against the elements while maintaining a clean, OE-inspired appearance. A precision laser-etched Vector Engineering logo completes the package.
Additional Lift with Billet Lower Collars
What separates the Preload Lift Kit from our standard ZR2 leveling kit is the addition of billet lower spring collars.
These collars work in conjunction with the upper components to provide additional front-end lift, giving Silverado ZR2 owners a more aggressive stance and increased clearance while continuing to utilize the capable factory suspension system.
Rather than relying on an oversized top spacer alone, the Preload Lift Kit distributes the lift through a purpose-built combination of upper and lower components designed specifically for the ZR2 suspension which provides a near stock ride quality.
Addresses the Factory Upper Bushing Issue
The Preload Lift Kit isn't designed simply to make your truck taller. Like our standard leveling kit, it was engineered to address the factory upper shock bushing issue found on Silverado/Sierra 1500 models.
By incorporating this solution directly into the leveling system, the Preload Lift Kit provides an upgrade that improves both the stance of the truck and an important interface within the factory front suspension.
Built Around the Silverado/Sierra 1500 ZR2/AT4X
The factory Silverado/Sierra ZR2 is already an extremely capable platform. The Preload Lift Kit is designed to build on that capability without requiring owners to immediately replace the complete factory suspension system.
For ZR2 owners looking for additional front lift, increased tire clearance, a more aggressive stance, and an upgraded upper shock mounting solution, the Preload Lift Kit delivers a complete package engineered specifically for the truck.
