KYB Shocks & Struts Gas-A-Just Rear GMC MOTORHOME CHASSIS 1973-78

You're getting a KYB Gas-A-Just rear shock absorber for your 1973 or 1974 GMC Transmode. This shock is built with a monotube design, which offers some advantages over older twin-tube styles. It's designed to automatically adjust to your driving needs, so you get a comfortable ride when you're cruising but more control when you need it. Plus, it won't lose performance over time due to aeration, which can happen with other shock types.

Inside, this shock has two separate chambers. One is for the hydraulic piston and valve, handling responsiveness and control. The other is a high-pressure nitrogen gas area with a floating piston. This setup means it provides a comfortable ride during normal driving, but it can instantly add performance when you demand it. Keeping your suspension working as the manufacturer intended is important, especially for modern electronic safety systems, and this shock helps ensure those systems function correctly.
