Overview

The triple chrome-plated piston rod reduces seal wear, contributing to longevity. Its higher gas pressure enhances steering response and helps keep electronic safety systems performing as intended.
Show original supplier description
Its high-pressure monotube design offers significant advantages over traditional twin-tube shocks, including instant and automatic adjustment to driving needs and resistance to fade caused by aeration. The shock features two distinct working chambers: a hydraulic piston and valve area for responsiveness, and a high-pressure nitrogen gas area with a floating piston for a comfortable ride that can instantly provide more performance when demanded. This construction, combined with the high-pressure monotube design, ensures fade-free operation and instant response to road conditions. The increased gas pressure directly contributes to improved steering response and helps maintain the optimal performance of modern electronic safety systems, which rely on the suspension, brakes, and tires functioning as the manufacturer intended. It is an ideal upgrade for vehicles that are used for work, towing, or have larger, heavier tires and wheels. The Gas-a-Just series aims to deliver a stock handling characteristic while offering a noticeable improvement in damping performance for a more controlled driving experience. It is a non-adjustable, medium-budget option for OE upgrade applications.
