Detailed Description

KYB Excel-G 340100 is engineered for the front left suspension position on the Infiniti EX35, EX37, and QX50. It is designed to restore the vehicle’s original control characteristics rather than alter ride height or handling behavior. With a compressed length of 11.88 inches, extended length of 13.83 inches, and 1.95 inches of stroke, this strut is built for the specified application and suspension geometry.

This part cross-references Monroe Shocks & Struts 72701 for the same application. KYB also recommends replacing the strut mount with SM5733 and protecting the assembly with strut boot SB103 to reduce noise, vibration, and contamination.
