KYB 5510054 Suspension Strut - Front

KYB Gas-a-Just Front Strut for Silverado and Sierra

• Internal rebound spring included
• Compressed length: 16.81 in; extended length: 20.49 in; stroke length: 3.69 in
• Lower mount type: E3(100x128x10)
• Upper mount type: S1(10MM)

Product Details

KYB Gas-a-just is the brand’s monotube performance line, built as an OE-style replacement for vehicles that need controlled damping without sacrificing normal ride comfort. Part number 5510054 is engineered for the front of factory-lifted Silverado 1500 and Sierra 1500 models, using a gas-charged monotube layout that separates the working hydraulic area from the nitrogen gas section for more immediate response when road conditions change. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Strut Helps Address

• Excessive front-end bounce over rough pavement
• Reduced steering control during braking or cornering
• Uneven ride quality after strut wear
• Front suspension instability on lifted truck applications
• Noisy or inconsistent damping from a worn OE strut
