Airbag cover Mansory for Mercedes G-class G500 / AMG G63 W463A

Airbag cover Mansory for Mercedes G-class G500 / AMG G63 W463A

The Mansory carbon airbag cover sits at the very centre of the W463A driver wheel — the part your eyes land on every time you grip the rim, and the part regulators care about more than any other piece in the cabin. This trim wraps the OEM driver-airbag module of the 2018+ G-class (G500, G550, G400d, G350d and AMG G63) in a thin 2K plain-weave carbon shell while retaining the original Mercedes 3-pointed star centre boss. Within the wider Mansory Carbon Body Kit for Mercedes G-class W463A G500/G63 programme it is one of the few interior parts that touches a regulated, life-safety component, so the engineering brief is the inverse of every other carbon trim: do not stiffen, do not reinforce, do nothing that could change how the bag tears out at 200 km/h.

Construction & Materials

The cover is laminated as a thin pre-preg skin over a moulded ABS sub-shell that mirrors the geometry of the OEM airbag lid. The carbon adds visual surface only — the structural tear path stays inside the OEM polymer, untouched. The lacquer is hand-polished after a low-temperature cure so heat does not change the polymer behind it.

• Weave: 2K plain weave, fine pitch, oriented so the warp runs vertically across the steering boss for symmetry left-to-right
• Cure: low-temperature autoclave (≤ 80 °C) — chosen specifically so the underlying ABS airbag lid is not heat-aged or warped
• Wall thickness: 0.6–0.8 mm of carbon skin bonded to the OEM-shape sub-shell; total cover thickness within ±0.4 mm of stock
• Weight: ~120 g, within a few grams of the factory plastic lid — no measurable change to wheel inertia or self-centring torque
• Mounting: bonded with controlled-failure 3M VHB along the perimeter of the OEM lid; adhesive line is interrupted along the engineered tear path so the bag still splits along the factory seam
• Centre boss: OEM Mercedes 3-pointed star emblem retained — chrome (standard) or matte black (option), pressed into its original recess, never glued over
• Finish: black gloss lacquer (default), satin, or natural carbon under clear UV-stable lacquer; UV inhibitor matched to dashboard plastics so the cover ages with the cabin
• Tear seam: OEM H-pattern weakness line in the underlying ABS is preserved; the carbon skin is scored and the adhesive omitted along this line so the cover splits cleanly when the bag fires

Design & Visual Function

Visually the cover does one job: it pulls the centre of the wheel into the same material language as the rest of the Mansory cabin — the dashboard inserts, the door switch panel, the speedometer top panel — without shouting. The 2K plain weave is deliberately finer than the 3K twill used on exterior parts, because at 30 cm from the driver's eyes a coarse twill reads as busy. Plain weave gives a quiet, almost woven-silk surface that catches the cabin ambient light and the headliner reflection in equal measure, never glaring.

The 3-pointed star is kept in its OEM position and OEM size. Mansory considered (and rejected) replacing it with a Mansory crown — the airbag lid is one of the few panels where Mercedes' own type approval covers the emblem placement and size, and altering the boss geometry would invalidate the deployment test. So the star stays. Owners who want the crown move it to the bonnet badge, the grill logo or the steering frame, all of which sit in the same eyeline and carry the brand without touching the safety part.

Geometrically the cover follows the OEM contour exactly — same crown radius, same depth from rim to boss, same chamfer at the spoke roots. Hands resting at six-o'clock or palms hooked over the top of the wheel feel no edge and no lip. The only tactile change is the substitution of plastic for lacquered carbon, and even that is tuned: the lacquer is mid-gloss, not high-gloss, so it does not become slick when warm.

Compatibility & Fitment

This airbag cover fits the Mercedes-Benz G-class W463A generation only — the 2018+ 4th-generation platform (Mercedes internal model code W463A, marketed simply as "G-class"). It covers G500, G550, G400d, G350d and AMG G63 (M177 4.0 V8 biturbo) when fitted with the factory driver-airbag module of that generation. Pre-2018 W463 (the original "boxy" G from 1979–2018) is not compatible — the airbag module geometry, electrical connector and tear pattern are completely different. W463A Gronos and W465 next-gen variants use a different cover and are not covered here.

LHD and RHD wheels share the same airbag module and therefore the same cover — no left/right SKU. The cover is independent of base vs AMG-package trim because the airbag lid itself is shared across G500, G550, G400d, G350d and G63. If the car has a non-OEM aftermarket steering wheel already fitted (a different brand of sport wheel, a flat-bottom retrofit), the OEM Mansory cover may not fit — confirm by photo before ordering.

Installation & Reversibility

Installation is the single point in this product's life cycle where things can go wrong, and the documentation reflects that. The job itself is short — about 30 to 45 minutes of physical work — but it touches a pyrotechnic device, so the procedure is non-negotiable. Disconnect the battery, wait at least 10 minutes for the airbag capacitor to discharge, remove the OEM airbag module from the wheel using the two side-access spring clips, disconnect the yellow airbag connector, peel the OEM plastic cover from the module along the factory perimeter (it is bonded, not screwed), clean the underlying ABS substrate with isopropyl alcohol, apply the Mansory cover with the supplied 3M VHB primer along the OEM perimeter only — never across the tear seam — and seat under firm, even pressure for 60 seconds. Reconnect the airbag harness, reseat the module, reconnect the battery, run a diagnostic scan to confirm no SRS fault codes, and only then drive.

The cover is technically reversible — the VHB releases under heat from a panel-flasher heat gun at low setting — but in practice we strongly recommend the work is done by a body shop or a Mercedes-trained technician, not as DIY. The reason is warranty: any independent removal of the airbag module logged by the SRS control unit will, in most jurisdictions, sit on the car's record. Owners doing the work themselves should at minimum film the procedure and keep the time-stamp. The Mansory cover does not affect the SRS warning lamp logic in any way — but any post-installation amber SRS light is a stop-driving event until cleared by a scan.

Pairing within the Mansory G-class W463A G500/G63 programme

The airbag cover is the centrepiece of a three-part wheel build. The natural siblings are the steering wheel surround and the wheels themselves: steering wheel panel surround at the lower spoke, Sport steering wheel I as the full rim replacement when the owner wants a flat bottom and thicker grip, and Sport steering frame as the carbon collar around the boss. Cars that already wear the Sport steering wheel I almost always specify the airbag cover at the same time — the OEM plastic lid against a full-carbon rim looks unfinished. Cars that keep the OEM rim and want only one carbon accent on the wheel typically pick this cover plus the Sport steering frame.

Maintenance & Durability

Wipe with a soft microfiber and an interior-safe cleaner — never an ammonia-based glass cleaner, which fogs the lacquer over months. Avoid alcohol wipes, sanitising sprays and citrus-solvent cleaners; they all attack the UV-stable clear coat. A light coat of carnauba interior wax twice a year keeps the carbon weave reading sharp and protects against the slow yellowing that desert sun and tinted-window UV bleed-through cause over a decade. Do not rest a coffee cup or phone on the cover — the centre boss carries weight only from the airbag itself, and a sharp impact from a dropped object can crack the lacquer over the tear seam, exposing the controlled-failure adhesive line. If the lacquer chips, do not patch it with shop touch-up — use the Mansory-supplied UV-cure repair pen, which is colour-matched to the original cure.

Lead Time & Warranty

Lead time is 3–4 weeks from order confirmation. Each cover is laminated, cured and lacquered on demand because the centre-boss recess is hand-finished around the 3-pointed star. The 12-month warranty covers manufacturing defects — delamination, lacquer cracking under normal use, voids in the carbon skin, adhesive failure of the perimeter VHB. It does not cover damage caused by improper installation, post-deployment replacement (a deployed airbag cover is consumable by definition), or aftermarket steering-wheel substitutions. Replacement after a deployment is supplied at a discounted rate against proof of incident.

FAQ

Q: Does this cover affect airbag deployment?
A: No. The OEM ABS airbag lid with its factory tear seam is preserved underneath. The carbon shell adds visual surface only. The adhesive line is deliberately interrupted along the tear path, and the carbon skin is pre-scored, so the bag splits along the factory H-pattern at the factory pressure. Mansory tests cover-equipped modules against FMVSS 208 and ECE R94 deployment criteria as part of the supply chain.

Q: Can I keep the OEM Mercedes star or change it to a Mansory logo?
A: The 3-pointed star stays. The airbag lid emblem placement is part of the type approval — substituting the boss invalidates the deployment certification. Owners who want the Mansory crown apply it to the bonnet, the grill or the steering frame, none of which touch the SRS.

Q: Is this DIY-installable?
A: Mechanically yes — about 30–45 minutes of work — but because it touches a pyrotechnic device we recommend a body shop or Mercedes-trained technician. Disconnecting and reseating the airbag module incorrectly will set an SRS fault and may void warranty on the safety system.

Q: What is the weight, and does it change steering feel?
A: ~120 g, within a few grams of the OEM plastic lid. Wheel inertia, self-centring torque and electric power-steering response are unchanged.

Q: After an airbag deployment, can I reuse the cover?
A: No. A deployed airbag destroys its cover by design — the tear seam splits and the lid hinges out of the way. The Mansory cover is consumable in the same way the OEM cover is. Replacement is offered at discount against proof of incident.
