Genuine Mazda Boot Lid Rubber Weatherstrip / Seal – PRHT • NE52-56-951B

Genuine Mazda Boot Lid Rubber Weatherstrip / Seal – PRHT

Replacement Genuine Mazda boot-lid weatherstrip for Mazda MX-5 Mk3, Mk3.5 and Mk3.75 NC models fitted with the power retractable hard top.

The moulded rubber weatherstrip fits around the luggage-compartment opening and seals against the underside of the closed boot lid. It helps prevent rainwater, road spray, dust and exterior air from entering the boot.

The seal installs onto the raised body flange surrounding the boot aperture. Its moulded profile must remain correctly seated around the complete opening so that the boot lid can apply even compression when closed.

Over time, the original rubber can become flattened, torn, hardened or displaced. A deteriorated seal can allow water or condensation to collect inside the luggage compartment and may contribute to damp trim, corrosion or persistent moisture around the boot floor.

One weatherstrip is fitted per vehicle, and this listing supplies one complete Genuine Mazda boot-lid seal.

Important roof-type restriction: NE52-56-951B is specifically for power retractable hard-top models. Soft-top MX-5 NC models use the different NE52-56-951 boot-lid weatherstrip.

Typical reasons for replacement:

• Seal loose or repeatedly lifting from the body flange
• Boot seal damaged during body or trim repairs
• Original weatherstrip missing or incorrectly fitted
• Visible deterioration around corners or joined sections

Fitment advice: Confirm that the vehicle is fitted with Mazda’s factory power retractable hard top. Do not order this seal solely from the vehicle year, because soft-top and PRHT models use different boot-lid weatherstrips.

Leak-diagnosis advice: Water in the boot is not always caused by the boot-lid seal. Inspect the rear lamp seals, drainage system, roof drains, body seams, aerial mounting and other luggage-compartment sealing points before assuming that the weatherstrip is the sole source of a leak.

Replacement advice: Remove dirt, old adhesive residue and corrosion from the body flange before installing the replacement. A distorted or corroded mounting flange may prevent the new seal from seating evenly.

Seal-care advice: Clean the rubber using suitable mild products. Avoid petroleum-based cleaners or lubricants that may soften, swell or damage the weatherstrip material.

Other items to inspect: Check the boot-lid alignment, latch adjustment, luggage-compartment trim, rear lamp seals, roof-drain outlets and boot-floor drain points while investigating water ingress.

Useful tools / consumables: Plastic trim-removal tools, mild cleaning solution, lint-free cloths and a suitable rubber-care product. Specialist tools are not normally required.

Difficulty guide: DIY Difficulty: Easy. The seal pushes onto the body flange, although careful alignment around the complete boot aperture is required.

Why Genuine Mazda? Genuine Mazda weatherstrips match the original boot-aperture profile, moulded corners, overall length and compression characteristics. Correct fit helps the boot lid close normally while maintaining an even seal around the luggage compartment.

What’s in the box: One Genuine Mazda boot-lid rubber weatherstrip for power retractable hard-top models, part number NE52-56-951B.

Installation notes: Open the boot lid and note the orientation and joining position of the original weatherstrip. Carefully pull the old seal from the body flange and clean the complete mounting surface. Position the replacement in the same orientation and press it fully onto the flange, working progressively around the opening without stretching the rubber. Ensure that all corners and moulded sections sit evenly. Close the boot carefully to check alignment and compression, then test the luggage compartment for water ingress.
