Dent Vision ShockBlocker X4 Knockdown | Dual Spring Shock-Free PDR Knockdown

Overview

The Dent Vision ShockBlocker X4 Knockdown is designed for technicians who want maximum control, reduced vibration, and a firmer knockdown feel during Paintless Dent Repair. Featuring a patent-pending dual spring shock absorption system, the X4 is tuned for maximum stiffness while still allowing controlled movement through the shaft to reduce impact transfer to your hands and fingers.

Built for daily professional use, the ShockBlocker X4 helps reduce fatigue during repetitive tapping, blending, and finish work while maintaining the crisp feedback technicians need for accurate panel correction.

Available in four color options: Red, Green, Orange, and Blue.

The result is a knockdown that feels precise without punishing your hands.
