Mod Mafia Ribbed Inspection Hub Covers
Inspection Site Glass
These Hub covers have a site glass installed so the level and condition of the fluid can be seen and monitored without removing the wheel or opening the fill plug. This is a large advantage over stock hub covers because if you get water in your hub you will be able to see the hub oil turn murky. Being able to see the level is important for general maintenance, but it’s extremely helpful on long road trips. It can add piece of mind if you discover a hub oil leak because then you will know if you need to tow your vehicle home or just drive it and fill when you get home.
We wanted to produce a ribbed hub cover to increase cooling. Although hubs are one of the most reliable pieces on the truck, that does not mean it could not be better. Our results over the course of months of testing has shown a reduction in the heat generated from driving by 36%. Example: we saw temperatures of 2wd Hummers get to 160F when ambient was 80F. With these covers it dropped the temp by 28.8F to 131.2F. This reduction in hub temperature will increase seal and oil life.
