Lube Locker Axle Housing Cover Gaskets: The RTV-Free Approach
Sealing a differential cover has traditionally meant scraping old sealant, laying a bead of RTV, and waiting for it to cure before adding gear oil. Lube Locker built its reputation on replacing that routine with a reusable gasket. Its axle housing cover gaskets slip onto the cover dry and seal against the housing without any silicone, which makes them a favorite for anyone who services differentials regularly.
How the Design Works
Lube Locker gaskets use a rubber-coated aluminum core. The rigid core keeps the gasket stable and evenly supported between the cover and the housing flange, while the rubber coating provides the actual sealing surface. Raised rubber beads help the gasket seal against gear oil and keep it from sticking to the mating surfaces, so it can come off cleanly at the next fluid change. Because no sealer is involved, there is no cure time, and the axle can go back into service sooner once the cover is torqued down.
Installation is straightforward, but the surfaces still matter. Clean the housing flange and cover thoroughly, and remove any leftover RTV or old gasket material with a solvent such as brake cleaner. Tighten the cover bolts in a crisscross pattern to apply even clamping force; Lube Locker packaging includes the recommended tightening order, and a torque wrench helps you hit spec without over-compressing the seal.
Applications Covered
Lube Locker's differential cover gaskets are built for popular off-road, truck and performance axles. The lineup includes gaskets for:
- Dana 30 differential covers
- Dana 44 differential covers
- Dana 60 and Dana 70 covers, which also fit the Ford Super Duty Dana 60
- AAM 11.5" axles found in late-model GM and Dodge trucks
Fitment is specific to each axle's cover shape and bolt pattern, so confirm your axle type before ordering. Many Jeep, truck and off-road builds use these axles, and owners who change gear oil often after trail use or towing see the biggest benefit from a gasket that can be reused.
Why Reusability Matters
With proper care, a Lube Locker gasket can be reused across multiple fluid changes. That suits racers who inspect differentials frequently, off-roaders who service axles after water crossings, and mechanics who want a repeatable, mess-free job. It also reduces the temptation to over-apply sealant, which can squeeze into the housing and contaminate gear oil.
