Cometic Ford 5.0L Gen-3 Coyote Modular V8 94.5mm Bore RHS .040in MLX Cylinder Head Gasket

Cometic's .040in MLX head gasket seals the right side (RHS) of the 5.0L Gen-3 Coyote V8, built for the 2018-2025 Ford Mustang GT, Bullitt, Mach 1, and Dark Horse, plus the 2018-2020 Ford F-150 Base. It's sized for a 94.5mm bore. Per Cometic, its HP shim technology raises clamp load around the combustion chamber to hold the seal on this engine's open deck block.

Why Upgrade to Cometic's MLX Head Gasket

Per Cometic, here's what the HP shim technology does:

• Built on HP shim technology as part of the MLX design.
• Adds clampload right around the combustion chamber.
• That extra clampload gives a tighter seal around the open deck block.

Fitment Notes

This RHS head gasket fits the 5.0L Coyote in the 2018-2025 Ford Mustang GT, Bullitt (2019-2020), Mach 1 (2021-2023), and Dark Horse (2024-2025), plus the 2018-2020 Ford F-150 Base. Does not fit the F-150 Raptor, or the Mustang EcoBoost, GTD, GT500, or GT350.

Install and Honest Talk

This listing is the right-hand-side (RHS) gasket only. If you're doing a full head gasket job on both banks, you'll need the left-hand-side counterpart too, it isn't included here. Cometic built this one around HP shim technology to hold clampload and sealability at the combustion chamber on the open deck block once it's torqued down, but a head gasket only seals as well as the install behind it. What else you need: [VERIFY: head bolts or studs and torque procedure, gasket sealant if called for, and whether a tune is required.]

Free US shipping over $99

Orders over $99 ship free by ground to the lower 48 states. Alaska, Hawaii and Canada are not included; shipping to those addresses is calculated at checkout. Some oversize or heavy parts (long-tube exhausts, bumpers, full lift kits) go freight instead of parcel: free to a commercial address with a loading dock, and residential freight delivery carries an additional charge.

When it ships

Parts ship direct from the distributor warehouse that stocks them, so dispatch timing depends on the part, not on a single cutoff. You get a confirmation with tracking as soon as it leaves, and tracking shows the delivery estimate for your address. If a part is backordered we email you an expected availability date.

Report a short shipment or shipping damage within 5 business days of delivery. For a packing error, send us the date or package code printed on the label along with the part number so we can trace it with the warehouse.
