ReadyLift Suspension RL 3 Rear Block Kit for 2025 Chevrolet Silverado and GMC Sierra

Upgrade the rear stance of your 2025 Chevrolet Silverado or GMC Sierra with the ReadyLift Suspension RL 3 Rear Block Kit. Designed for applications requiring a 3-inch rear lift, this kit helps create a more balanced appearance and supports proper suspension geometry when paired with a compatible front leveling or lift setup. The ReadyLift Suspension RL 3 is engineered for a direct, vehicle-specific installation using the factory-style rear suspension layout.

Built for dependable performance, the kit uses durable rear lift blocks and supporting hardware to raise the rear of the truck while maintaining the original leaf-spring suspension design.
