Domiworks Chevy LS/LT/SB/BB to 8HP 70/90 N63 N73 N74 Adapter Kit

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.

Adapter plate and converter adapter made out of high grade aluminum and natural/black anodized for a premium feel and experience.

Includes three bolt pattern on the backside of the converter adapter to support multiple chevy and converter bolt patterns. The following PCDs are:

- 10.75" (6-bolt)

- 11.08" (6-bolt)

- 11.5" (6-bolt)

Adapter plate thickness is 35mm.

Laser etched markings.

Note! Recommended to use a non-shrouded starter, otherwise you need to trim the adapter and gearbox bellhousing.

Note! If you have a SB/BB engine please make a note while ordering as the center guide and bolts are different.

Note! This kit supports both long and short-nosed crank, however if you have a long nose crank the center guide needs to be shortened and modified. Reach out to us before ordering.

Adapter kit includes:

- LS to 8HP Adapter plate

- Converter adapter and guiding pin

- Mounting hardware such as bolts and dowels. Please select your version to get the correct bolts.
