Hahaha! Ive seen em on the diesels as welll. Post up some pics once its installed!
I run one on my prerunner with the m220/d46HD.
These advantek axles hold so little oil…
We used to cook the rear diffs in the crown Vic during some prolonged car chases in the city… mostly because they were so shoddily maintained.
And then when I started working on a project with the R180 and R200’s I got to learn about power and heat in the diff.
So a diff cover that had cooling veins and then also a pump and heat exchanger,
Anyways my d46 would get hot at speed offroad but got to the critical point when I went to 33’s and then got better with a regear and 35’s but that may have been for other reasons like me getting scared.
Diff cover that held more fluid and had a giant heat sink on it and the temps dropped significantly.
Only downside is the aluminum ones aren’t as tough as steel if you do any rock work.
Apparently there are some large capacity d60 covers in steel.
I will put a temp strip on the oem cover and shaft tube and by the pinion seals to see what temps they generate this spring on the next trip. If the temps get high… then cover.., if not then no.
I’m getting slower in my acheyness.
Tl;DR they work but are more fragile than steel. Don’t believe Banks. He made that video to release his product. His product is good too. But he slung a lot of bs in that video
