Stopper Bush Absorber Front > MAZDA 3 BK / MAZDA 5 / BIANTE > BP4K 34 111C > GENUINE PART

This is a Genuine OEM Front Shock Absorber Bump Stop, identified by the Mazda part number BP4K 34 111C. This component is a critical standardized part used across several Mazda vehicles that share the C-platform architecture, including the compact sedan Mazda 3 (BK chassis), the compact MPV Mazda 5, and the larger MPV Mazda Biante.

The Stopper Bush (or bump stop) is made of a durable, compressible, and progressive-rate material. It is fitted onto the strut piston rod and acts as a final cushion, absorbing the highest-force energy when the suspension is fully compressed (e.g., hitting a large bump or heavily loading the MPVs). This prevents harsh, damaging metal-on-metal contact (bottoming out), which could compromise the strut's performance and lifespan.

Replacing an old, brittle, or cracked bump stop with the Genuine Part ensures:

✔ Direct Fit: Guarantees correct fitment and optimal energy absorption characteristics for all compatible Mazda platforms.

✔ Strut Protection: Prevents internal damage and prolongs the service life of the front struts.

✔ Ride Consistency: Maintains the designed travel limits and contributes to stable and comfortable handling.
