I bought my JDM trussed 8.2 rear axle housing from Megazip earlier this year and had it shipped from Japan (that was a hard part to get but saves me the hassle and some of the cost relative to upgrading to a 9.5" or a Dana 60).Absolutely. I traveled to japan last year and everything was about 30%-40% off compared with the price for the same thing back in the States.
I think the USD price for the housing was something like $500. Less than half what the USDM, non-trussed version cost from my local dealer. Shipping was actually more than the housing was, but it came within a few days via FedEx air. I don't see Toyota can fabricate the housing for $500 USD, paint it, and still make a profit. Must just be the exchange rate allowing to make them parts so cheaply.
