Chevy LS/LT/SB/BB to 8HP 45/50/70/75/90 N57 B57 B58 N63 N73 N74 Adapter Kit

One adapter to rule them all! Our popular LS to 8HP just got a new revision and this time we have fitted 3 8HP Transmission bolt pattern into one adapter. This means you can now bolt a 8HP50 B58, 8HP70 N63 or a 8HP90 N73/N74 to the same adapter.

There will be two different TC Adapter versions depending on what transmission you are going to fit. Please select in the meny which tranmission you are going to use in the dropdown menu.
