KYB 339422 Suspension Strut - Front

KYB Excel-G Front Suspension Strut

The KYB Excel-G 339422 is a front suspension strut for select Buick, Chevrolet, and GMC SUVs and crossovers. Built to restore original ride control and handling, it is a direct OE-style replacement for drivers who want factory-correct response on the road.

As part of the KYB Excel-G line, this strut is calibrated to return the vehicle’s designed performance rather than change it. It is made on KYB OE assembly lines and uses OE-quality components, making it a practical choice for a 2013-2017 Buick Enclave front strut replacement, a 2013-2017 Chevrolet Traverse front strut replacement, or a 2013-2016 GMC Acadia front strut replacement.

• Triple-lip fluid seal helps reduce oil and gas leakage
• Vehicle-specific, hand-assembled damping valves manage tire contact, steering response, and body movement
• Strong strut body and bracket design helps minimize flex and maintain alignment

Excel-G Product Line Details

The KYB Excel-G line is built for restoring original suspension behavior on vehicles that rely on precise damping for ride quality and electronic safety system performance. KYB supplies shocks and struts to new vehicle manufacturers, and the Excel-G is produced on the same OE assembly lines using the same quality standards. Part number 339422 follows that OE-focused approach for front suspension service on the Buick Enclave, Chevrolet Traverse, and GMC Acadia.

What This Strut Helps Address

• Excessive bounce or float after bumps
• Reduced steering response during lane changes
• Front-end instability under braking or cornering
• Uneven tire contact caused by worn damping
• Suspension noise or fluid leakage from a worn strut assembly

Installation Notes

Fits 2013-2017 Buick Enclave, front; 2013-2017 Chevrolet Traverse, front; 2017 GMC Acadia Limited, front; and 2013-2016 GMC Acadia, front. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify compressed length, extended length, stroke length, and upper mount type before installation. This part cross-references Monroe Shocks & Struts (e.g., 72518, 72949) for the same application.

Quality Assurance

KYB builds Excel-G struts on OE assembly lines with OE-quality components and vehicle-specific damping calibration. The design supports the suspension performance that electronic safety systems expect from the vehicle’s original setup.
