## Overview

The KYB 554384 Gas-a-Just Gas Shock is a high-performance, monotube OEM replacement shock absorber designed specifically for Hyundai vehicles. Featuring a high gas pressure system and an air-free hydraulic unit, it delivers instant control, superior handling, and fade-free reliability. Finished in machined silver, it offers a perfect vehicle-specific fit for seamless installation and restored driving dynamics.

## Description

The KYB Gas-a-Just monotube shock absorber has additional performance advantages over the traditional twin-tube design: It can instantly, automatically adjust to your performance needs and never experiences fade due to aeration. The Gas-a-Just is available as an OE monotube replacement and as an OE twin-tube performance upgrade. The KYB Gas-a-Just has two separate working chambers: An air-free hydraulic piston and valve area for responsiveness & control, and a second high-pressure nitrogen gas area with a floating piston that provides a comfortable ride during normal driving and adds instant performance on demand.

Review: Veloster Rear end jump/bump steer 99% gone - 2013 Veloster base dct. OMG been considering a rear torsion bar for a year. Now bought these instead for less cost than a bar. These shocks solved almost all of the rear end jumping out of line on bumps, causing twitchy steering. Hated it for a long time. Even replaced old rear shock absorbers with factory ones, still had the same problem. Just took a 40 min drive. And they aren't too stiff by any means for a lightweight car like this. Holy cow so much better. Hopefully longevity is good. Considering kyb front struts. I also carry a 120lb sound system in the trunk. These do awesome with that too. Night and day difference. 2 year update: still BETTER than new factory absorbers. BUT broke in very well now the steering issue partially came back...Not to the point of complete frustration like before. Still satisfied enoigh with the price for how much of the issue is resolved.
Review: Easy 30 to 45 minute installation if you have - Installed two rear KYB #554384 Gas-A-Just Shocks on a 2015 Kia Forte5 SX with 54,000 miles. Same rear suspension as a Hyundai Elantra and Veloster. BIG improvement in the ride: much less rear end hop and crashing noises over bumps, less stepping sideways, quieter inside. I wish I had installed these 30k miles ago. These shocks are a huge improvement over the stock units and are a very inexpensive upgrade at ANY MILAGE. Easy 30 to 45 minute installation if you have: a floor jack, jack stands, torque wrench and a rubber mallet. There are a couple of YouTube videos that step you through the process or buy a pair of these and point your mechanic to the videos. We’ll see how they last. Highly recommended.

### ⭐⭐⭐⭐⭐ The perfect shock absorber
*by A***S on August 24, 2024*

2017 Kia Forte5 LX. One of the reasons I decided to replace my rear shocks at 62,000 miles was because my OEM shocks were no longer able to safely hold the load of 4 passengers. The other reason, of course, was for better performance overall when I drive. My car now seems to brake and accelerate faster, react to steering inputs quicker, and turn out of corners easier without losing traction on the inside wheels. And as other Hyundai/Kia owners have stated, I also feel like I should have swapped the rear shocks out with KYBs much sooner.
