Ditch the Silicone: Benefits of Using a Differential Cover Gasket

Published by Dustin Babich on

Differential cover gasket provides better protection than silicone. When changing the differential fluid, it’s crucial to choose the correct gasket or sealant to prevent leaks.

Some mechanics prefer using silicone because it can be more forgiving when it comes to small surface imperfections or uneven mating surfaces. However, using silicone as a replacement for a gasket may not hold up to vibration or heavy-duty applications.

On the other hand, using a differential cover gasket provides a reliable and long-lasting seal, making it a better choice for heavy vehicles or off-road.

A differential cover gasket may be your go-to choice if you’re looking for a more straightforward replacement option that requires minimal time and effort. Conversely, if you’re after a more permanent seal, silicone may be the ideal choice for you.
