KYB 5510018 Suspension Strut - Front

KYB Gas-a-Just Front Suspension Strut

The KYB Gas-a-Just 5510018 is a monotube front suspension strut built as an OE-style replacement for trucks and SUVs that need restored control, steering response, and ride stability. It is engineered for Chevrolet, GMC, and Cadillac applications where the suspension works harder under towing, hauling, or larger wheel and tire setups.

Gas-a-Just Product Line

KYB Gas-a-Just struts use a monotube design with separate hydraulic and high-pressure nitrogen gas chambers. That layout supports quick response, consistent damping, and fade-resistant operation during demanding driving, while still maintaining a controlled ride in normal use.

Key Features

• OE-style monotube replacement for front suspension service
• High-pressure monotube design separates gas and oil for consistent response
• Built for vehicles that tow, work, or run larger, heavier tires and wheels
• Triple chrome plated piston rod helps reduce seal wear from fluid leakage
• Higher gas pressure improves steering response
• Supports proper operation of electronic safety systems when the suspension is maintained as designed
• Part number 5510018 for direct catalog identification

Detailed Description

KYB 5510018 is designed to restore the original handling characteristics of front suspension systems on select Cadillac Escalade and Escalade ESV, Chevrolet Tahoe and Silverado 1500, and GMC Yukon, Yukon XL, and Sierra 1500 models. The monotube construction uses an air-free hydraulic working area for control and a separate nitrogen gas chamber for immediate damping response. This helps maintain stable ride quality on vehicles that see load changes, towing, or heavier wheel packages. The part number 5510018 is also cross-referenced to Monroe Shocks & Struts 39112 for the same application.

What It Helps Address

• Excessive front-end bounce or float
• Reduced steering response after shock or strut wear
• Ride fade during towing or heavier-duty use
• Oil seepage related to seal wear
• Loss of suspension control on full-size SUVs and trucks
