✔ Designed specifically for the third-generation Mazda 3 (BM/BN chassis, 2014-2018).
✔ Location: Front Axle Suspension (inside the front strut assembly)

This is a Genuine OEM Front Shock Absorber Bump Stop, identified by the Mazda part number B45G 34 111A. This component is critical for the front MacPherson strut suspension system of the third-generation Mazda 3 (BM/BN chassis), which utilizes Mazda's Skyactiv Technology platform.
The Stopper Bush (or bump stop) is made of a carefully calibrated, progressive-rate material. It is fitted onto the strut piston rod and acts as a progressive cushion to absorb the final, high-force energy when the suspension is fully compressed (e.g., severe road impacts or hard driving maneuvers). This prevents harsh, damaging metal-on-metal contact (bottoming out), which could compromise the strut's performance and the vehicle's handling stability.
Replacing an old, brittle, or cracked bump stop with the Genuine Part ensures:
✔ Direct Fit: Guarantees correct fitment and optimal energy absorption characteristics for the Mazda 3 BM/BN.
✔ Strut Protection: Prevents internal damage and prolongs the service life of the front struts.
✔ Ride Consistency: Maintains the precise suspension travel limits designed to deliver the car's intended balance of comfort and dynamic handling.
