Differential Gear Oil weight

This is one of the diff covers available for the Raptors that Boss Hoss was referring to. They work well for cooling the differential and have the drain plug and dipstick. We sell them, but they have been on back order for a while. We are hoping to have more in within the next 2 weeks.

Ive been using Amsoil Severe gear 75w-90 or 75w-140 for years in all my other cars. Very happy with it.
