Teraflex AdvanTEK HD Differential Cover Reviews

The installation was easy! It’s very robust compared to the OEM differentials covers. What got me so interested in these in first place was the large diameter fill tube/inspection port at the top that can accommodate a funnel! It’s a very well designed product!

Bolts were terrible.
