Ford 9.75 Differential Cover Gasket Lubelocker

Easy to install in my 2011 Ford SVT raptor rear diff paired with a Spicer diff cover. No leaks yet, will update if that changes. Well worth the purchase price as of now. Way better than dealing with RTV gasket sealer or leaky cheap gaskets

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.

No leaks

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.

Amazing quality perfect fit for my 2021 9.75 Rear Diff.
