Also, most cars have cast rearends. My cars....Not 1 seeps oil.
So thickness, or quality of cast ?
And zero quality control @VTT. When you order the cheapest stuff from China and then put on a 40% margin this kind of stuff tends to happen.
China is notorious for this shit. You can get great quality products made there but you have to pay for it. When another china cast vendor offers you the same cast VC for 1/2 the price but with shit quality control but your margins increase 20% a greedy company compromises on quality for margin.
VTT return policy: if you install it you can't return it. You don't know about the shitty fitment or quality of their products until you install and find out the issues. At this point it is your problem not theirs. Blame the customer 100% seems to be their customer service model. You used the wrong oil, warranty declined, you installed it yourself, warranty declined etc. Remember when vtt was going to require you to send in a Blackstone oil report before you could get a warranty replacement? The only reason you do this is to make returns cost more, take longer, and easier to deny. God forbid you did an oil change and did not send it to Blackstone. Warranty denied!
Why people are surprised at VTTs quality this many years later is beyond me. They have had bad quality and CS since day 1. Things only got worse when they outsourced everything to China and just became a Chinese distributor of cheap parts with high margins. What a great American company.
