The TeraFlex Heavy Duty Dana 44 differentials have been fabricated to withstand debris, impacts, and most likely Armageddon. This has been achieved through the massive 3/8" thick high strength ductile iron construction.
This design also features recessed bolt holes so that the hardware does not get caught on anything else, and yes that is a possibility. The drain plugs, as well as the refill plugs are in an easy location, and the outer cover has been powder coated a sleek black finish for abrasion resistance.
