LubeLocker For 9.75" Differential Cover Gasket

2015 F150 XLT 4x4 perfect fit. Look at the shape and bolt pattern if yours looks as pictured, it will fit. Owned truck from day 1 and had some gear oil on the lower cover. never dripped or got worse. 10 years later time to change out all fluids. Ford saved $20 using a $1 worth of silicone instead of a gasket, disgraceful. No way i was going to redo this job with the silicone process and wait for it to set and then torque correctly especially after having leak from day 1. You think the factory did it right? NOT, no wonder was wet from day 1, i bet my experience is not unique for F150s. Hardest part of this job was to clean all that old silicone off with a scotch pad on air grinder (cover the gears with rags). After that was done, just cross bolted cover back in place with gasket in between, done. Now, I can pull and replace cover with none of that work, it's reusable. At the end of the day, good quality product, great fit, less effort/time, reusable, well worth the price.

Ford, in it's ongoing wisdom, decided to put different rear ends in the same model year trucks so you cannot go by the year to determine fit. The number of bolts on the cover are the same and not even the VIN identifies which one is used, you must look at the differential and not if it is more round or has a slight "ear" pointing toward the passenger side of the truck. The one with the slight ear is the 9.75" differential this is made for. No matter the size differential you have, none of them have a drain plug meaning that every fluid change will entail removing the cover. You can either remove the RTV and clean the surface, reapply RTV, and repeat every fluid change or save time and hassle by using a gasket. The LubeLocker gasket was well protected in shipment by the packaging and the quality is apparent on first inspection. There are multiple sealing lines around the gasket ensuring a leak free experience even if one somehow gets damaged. The material feels solid and although it will be hidden from view when installed, it looks nice. This is a perfect fit for the 9.75" differential and best of all, it is reusable so buy once, cry once. Total time for a fluid change with the LubeLocker is roughly 15 minutes with most of that being cleaning up the cover and wiping out any sludge. Compare that to almost an hour of scraping old RTV off the sealing surfaces and then removing residue. The most important question, does it work? I've had mine installed for two weeks and not a single drop for a leak. I highly recommend this as a replacement for the RTV if you do your own maintenance.

Good fit and no leaks for 2013 F150

Installed this on my 2020 Ford F-150 Raptor. First time ever doing a differential job before, and this gasket made it quick and easy and so far has not leaked! Just make sure you scrape the surface clean and line it up correctly. Much better than using RTV.

The best diff gaskets out there. No mess and reusable. Highly recommended. Fits a 2019 F150 XLT perfectly.

No leaks a few months in now, very easy service for rear.

Great gasket, will see on durability and resuseability in the future. Packaging was good quality, heavy duty and protective. Fit F150 with 9.75" perfectly. Sealed cover/differential well, no leaks. 1000× better than RTV and no mess what so ever. Clean flat mating surfaces and this gasket is all you need.

Quality gasket and worked as expected. 4 out of 5 stars as its over priced for a hyped up diff gasket.
