🧾 Overview
The TeraFlex 9550 VSS Twin-Tube Shock Kit is a complete shock upgrade for Jeep Wrangler JK, designed to improve ride quality, control, and durability on lifted vehicles running approximately 2.5" of lift.
These shocks use a vehicle-specific valving (VSS) system, tuned specifically for JK suspension geometry to deliver a balanced ride both on-road and off-road. The twin-tube design provides increased travel and durability, while maintaining a smooth, controlled feel compared to factory shocks.
Built for real-world use, the oversized shock body, triple-chrome plated rod, and internal travel limiter all work together to handle off-road abuse while keeping daily driving comfortable.
