Fel-Pro 06-15 Mazda MX-5 Miata/07-12 CX-7/10-13 3/12-17 5/03-08 6 Engine Crankshaft Seal Kit

A Fel-Pro engine crankshaft seal kit, part number BS40689, listed in our fitment data for the 2015-2021 Ford Mustang EcoBoost. Its job is to seal the crankshaft. This is a repair part, not a power part: you fix the seal and get back to driving.

Why Upgrade to a Fel-Pro Seal Kit

Per Fel-Pro, here is what the kit is built to do:

• Deliver a reliable seal, including on the applications the brand calls troublesome, so the job holds once it is done.
• Handle imperfect sealing surfaces. A mating face that is not perfect is planned for in the design, not something you have to work around.
• Use proprietary materials. Fel-Pro does not spell out what they are, and the stated aim is a seal that holds under real-world repair conditions, not a lab surface.

Fitment Notes

Our fitment data lists this kit for the 2015-2021 Ford Mustang EcoBoost only. Does not fit Mustang GT, GT350, GT500, Mach 1, Bullitt or V6. [VERIFY: the product title names Mazda MX-5 Miata, CX-7, 3, 5 and 6 applications and does not mention Mustang, so the title and our coverage data disagree; confirm BS40689 fits the EcoBoost Mustang before ordering.]

Install and Honest Talk

Straight talk: the install requirements for this kit are unknown. Nothing on file says what comes off the engine to reach the seal, what tools you need, what stays in place, or what torque to use going back together. Do not guess. Read the included instructions before you pull anything apart, and match the part number against your engine. The real tradeoff is that this is a fix, not an upgrade: you will not feel anything from the seat when it is done, and the payoff is a seal that holds. The fitment conflict above means a wrong order costs you the wait and a return, so check it first.

What else you need: [VERIFY: supporting parts, hardware in the box, tools, sealant or other consumables, and whether any other seal or gasket should be replaced at the same time.]

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.
