KYB 343442 Shock Absorber - Rear

KYB Excel-G Rear Shock for Toyota Yaris

The KYB Excel-G 343442 is a rear suspension shock absorber built to restore original ride control on select Toyota Yaris models. It is an OE-style replacement for drivers who want stable handling, predictable braking response, and consistent lane-change control without changing the vehicle’s factory tuning.

This makes it a practical choice for replacing worn rear shocks that can contribute to excess bounce, reduced stability, uneven tire contact, and slower response during braking or cornering. This part cross-references Gabriel G51783 for the same application.
