I have a 2004 3.9 v6 mustang. I was thinking about an 8.8 or i might try to save money and just go with a traction lock. I know theres 3 different kinds for the v6; ford t-lock, detroit tru trac, and eaton i forget their brand. I hear that the eaton and detroit ones are stronger than ford;s.

Anyways how much they would be installed with 3.73's? or should i do 3.53?
Whats some good shops in the area?

Thanks
