What you see is what you get — exact item, as pictured. Want it upgraded? We’ll refurbish it to your spec.
aFe Power front and rear cast aluminium differential covers supplied with gear oil for the 2020–2025 GM 2500HD / 3500HD 4WD.
A differential cover does three jobs: it keeps the gear oil in, it keeps debris and impacts out, and — if it is designed for it — it helps get heat out of the oil. The factory stamped-steel cover does the first well enough and the other two badly.
aFe's covers are cast aluminium with reinforcing ribs, which adds strength and heat dissipation as well as fluid capacity. More oil at a lower temperature is exactly what a differential wants when the truck is towing.
This is the complete kit: front and rear covers together with the gear oil to fill them, so a differential service and a cover upgrade happen in the same afternoon rather than in two parts orders.
Keeping rear differential temperature down is the point on a truck that tows — that is where the heat goes.
