Monroe 5654 is engineered as a rear replacement shock for vehicles that use stock suspension components and need OE-style ride restoration. The OESpectrum Passenger Car Shock Absorber line is focused on maintaining original factory drivability while improving control over body motion and road inputs.

Compatible With 2007-2008 Infiniti G35, rear; 2011-2012 Infiniti G25, rear; 2009-2013 Infiniti G37, rear; and 2015 Infiniti Q40, rear.

Confirm upper stem and lower clevis mounting styles against the original shock absorber, and compare compressed and extended lengths to the OE unit before installation. Use the vehicle’s service information for torque specifications and final inspection.
