KYB 554375 Shock Absorber - Front

KYB Gas-a-Just Front Shock for Ram 1500

The KYB Gas-a-Just 554375 is a front suspension shock absorber for Ram 1500 and Ram 1500 Classic applications. Built as a monotube performance upgrade, it adds firmer control for trucks that work, tow, or run larger wheels and tires while maintaining a controlled ride in normal driving.

Gas-a-Just shocks use a high-pressure monotube design that separates gas and oil for quick response and fade-resistant operation. For Ram 1500 owners looking for a direct-fit front shock upgrade, part number 554375 is engineered around the demands of heavier-duty use.

Key Features

• Monotube shock absorber with separate gas and oil chambers for consistent damping
• Up to 25% more damping performance than original equipment shocks
• Designed specifically for Dodge Ram and Ram truck applications
• High-pressure nitrogen gas helps deliver immediate response and improved steering feel
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Supports vehicles used for towing, hauling, and larger tire and wheel setups
• Helps electronic safety systems operate as intended by maintaining suspension control
• Compressed length: 9.84 in; extended length: 14.05 in; stroke length: 4.21 in

Product Details

KYB Gas-a-Just shocks are built for drivers who want more front-end control without giving up everyday drivability. The monotube layout keeps the hydraulic working area responsive, while the high-pressure gas chamber adds damping on demand when the truck sees heavier loads or more aggressive road inputs. This makes the KYB Gas-a-Just 554375 a practical choice for Ram 1500 front suspension service where OE-style comfort and added control both matter.

This part cross-references Monroe Shocks & Struts 911300 for the same application.

What It Helps Address

• Excessive front-end bounce after bumps or dips
• Reduced steering response on Ram 1500 and Ram 1500 Classic trucks
• Shock fade during repeated suspension movement
• Loss of control from worn or leaking front shocks
• Instability when towing, hauling, or running heavier wheels and tires

Installation Notes

Compatible With 2009-2010 Dodge Ram 1500, front; 2011-2012 Ram 1500, front; 2013-2018 Ram 1500, front; 2019-2021 Ram 1500 Classic, front; and 2022-2024 Ram 1500 Classic, front. This shock is for vehicles without air suspension. Verify upper and lower mount types before installation: upper mount S1 (12 mm) and lower mount E3 (65.4 x 94 x 5). Confirm compressed and extended length against the original shock before service.

Quality Assurance

KYB designs Gas-a-Just shocks with a monotube construction and high-pressure gas separation to maintain consistent damping performance. The triple chrome plated piston rod is used to reduce seal wear and support long-term shock operation in demanding truck applications.
