Genuine Mazda NH52-50-2J1A Rear Bumper Retainer – LH

Replacement Genuine Mazda left-hand rear bumper retainer for Mazda MX-5 Mk3.5 and Mk3.75 / NC facelift models with 1.8L and 2.0L petrol engines from 2009 to 2015 listed in the compatibility table.

The retainer mounts between the left-hand rear quarter-panel area and the side edge of the rear bumper cover. Its locating slots and attachment points hold the bumper corner securely against the vehicle body and help maintain the intended panel alignment.

Correct bumper-retainer condition is important for keeping the bumper edge flush with the adjoining rear body panel. The retainer supports the bumper during normal vehicle movement and helps prevent vibration or separation around the side mounting area.

This listing supplies one Genuine Mazda left-hand rear bumper retainer. One is fitted to the left-hand side of the vehicle. The corresponding right-hand retainer, part number NH52-50-2H1A, is supplied separately.

Replacement may be required where the original retainer has cracked, distorted, lost one or more locating tabs or become damaged during bumper removal or accident repair. Possible symptoms include the bumper corner sitting proud, an uneven panel gap, movement when the bumper edge is pressed or the bumper repeatedly disengaging from the body.
