What This Shock Helps Address

• Excessive front-end bounce after bumps or dips
• Loose steering feel or delayed lane-change response
• Reduced tire contact and uneven body motion over rough pavement
• Handling changes caused by worn original shocks
• Suspension performance issues on Chevrolet Silverado 1500 and GMC Sierra 1500 front applications

Installation Notes

Verify the vehicle’s suspension package before ordering, especially electronic suspension, Quadrasteer, Z71 Off Road, Z55 Autoride, and Premium Smooth Ride configurations. This front shock uses a special lower mount and an S1 upper mount, so match the mounting style to the original part before installation. Confirm compressed length, extended length, and stroke against the existing shock to ensure correct application on the Silverado 1500, Sierra 1500, Tahoe, Yukon, and related models.

This part cross-references Monroe Shocks & Struts 37178 and Gabriel G63803 for the same application.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers and builds Excel-G on the same OE assembly lines using OE-quality components. The 344381 is calibrated to restore original vehicle performance characteristics and support proper operation of suspension-related electronic safety systems when the rest of the vehicle is functioning as designed.
