tech note

The bolt pattern on Dana-Spicer Dana 50 monobeam, Dana 60 and Dana 70 series axles is the same. The covers however, have different top and bottom flange widths. For Dana 50 monobeam, Dana 60, and Dana 61 axles, order QU42029.

tech note

Starting in the 1970's, Dana-Spicer switched from light gauge steel covers with embossed mating flanges to heavy gauge covers with flat mating flanges. Gaskets were used to seal the early covers, but the late covers used RTV sealant instead of gaskets. Due to the Design of the older covers, you MUST use a cut gasket for a leak proof seal between the cover and diff housing. With the late, flat flange covers, you can use either RTV or a cut gasket. The advantage of RTV, is that properly installed on clean dry surfaces and using a grade of RTV that is resistant to gear lubricants (see S82194 RTV), it will not leak. The disadvantage is the covers sealed with RTV are hard to remove at the next service interval and once removed, the RTV residue stuck to the mating flanges must be laboriously cleaned off both surfaces. Our Spicer® QU420 series reusable diff cover gaskets provide superior sealing, easy removal and minimal clean up.

tech note

QU42030 Dana 70/Dana 70HD Reusable Gaskets are manufactured by Dana-Spicer. These excellent gaskets feature a woven steel core, non-asbestos facing, and are coated with Teflon® so the gasket does not stick to your axle housing or cover. Do NOT use RTV sealant with these reusable gaskets!
