Installation Notes and Tips

Verify compressed length, extended length, stroke length, and mount types before installation. This KYB Excel-G 344466 uses lower mount type E2(14X42.5) and upper mount type E3(61.6X87X25). For 2006 Isuzu i-350 and 2007 Isuzu i-370 applications, follow the manufacturer’s instruction to replace the suspension strut and coil spring assembly as directed. Always confirm rear-position fitment against the vehicle’s suspension configuration before service.

KYB supplies shocks and struts to new vehicle manufacturers, and Excel-G is produced on the same KYB OE assembly lines using OE-quality components. The design focus is restoring original ride control and handling characteristics for the listed Chevrolet Colorado, GMC Canyon, and Isuzu applications. This part cross-references Monroe Shocks & Struts 911230 for the same application.
