Genuine Mazda NF79-50-2H1B RH Rear Bumper Side Retainer

Replacement Genuine Mazda right-hand rear bumper side retainer for Mazda MX-5 Mk3 / NC pre-facelift models from 2005 to 2009 listed in the compatibility table.

The retainer is mounted behind the right-hand rear bumper corner where the bumper cover meets the rear quarter panel.

Its locating channels and mounting points support the side edge of the bumper cover, helping hold it securely against the body and maintain the intended alignment and panel gap.

Replacement may be required if the original retainer is cracked, distorted, impact-damaged or has broken locating points. A damaged retainer can allow the bumper corner to sit proud, sag, move or repeatedly detach from the body.

This listing supplies one Genuine Mazda right-hand rear bumper retainer. The corresponding left-hand retainer is a separate component.

Fitment advice: This is the right-hand retainer for the original pre-facelift Mk3 / NC rear bumper. Mk3.5 and Mk3.75 facelift bumpers use different retaining components.

Inspection advice: Inspect the bumper-cover locating tabs, rear quarter-panel mounting area, retaining screws and adjoining brackets before installation. A new retainer will not correct a torn bumper tab, distorted body panel or incorrectly fitted bumper cover.

Other items to consider: When replacing this component, consider purchasing the corresponding left-hand retainer, bumper screws, plastic clips and any adjoining brackets damaged during removal or impact.

Useful tools / consumables: Plastic trim-removal tools, panel-clip remover, suitable screwdriver and socket set, together with replacement bumper clips and fasteners where required.

Difficulty guide: DIY Difficulty: Moderate. The rear bumper normally requires partial or complete removal to access the retainer without damaging the bumper cover, locating tabs or surrounding paintwork.

Why Genuine Mazda? Genuine Mazda bumper retainers are manufactured to the intended profile, mounting-point positions and locating-channel dimensions for the original bumper cover and body panel. Using the correct OE component helps restore accurate bumper alignment and secure attachment.
