KYB 349027 Shock Absorber - Rear

Rear Shock Absorber for Infiniti FX

The KYB Excel-G rear shock absorber is built to restore original ride control, stability, and handling on select Infiniti FX models. This KYB Excel-G 349027 is a direct-fit suspension shock absorber for the rear position on the 2003-2008 Infiniti FX35 and FX45.

Excel-G is KYB’s OE-style product line, assembled on the same KYB production lines used for original equipment components and calibrated to return the vehicle to its designed damping characteristics. For Infiniti FX35 and FX45 rear suspension service, part number 349027 is a practical replacement choice when the goal is to recover factory-like control without changing the vehicle’s intended ride behavior.
