Ive been looking into this as well. As of now no one has a selectable locker available for the car 12 bolt. The 9" is covered. But i heard that a new electric locker will be comming out within the next couple of months. And i was told it will be the best design for stength. It is also probable that a car 12 bolt option will be released. I ve seen thes on many trail rigs and they work great and i think it would be a great idea/option for street/strip cars. As to the price yeah there more expensive than lockers or spools. But truck guys also have been using cable actuated lockers for years and i would think someone who has the resources available could make these work for the car 12 bolt and would be much more wallet friendly.
thanks for the info hokie. i friend of mine asked me at work about the set-up and i couldnt give him an answer as i have never seen a thread covering the topic. i am still wet behind the ears when it comes to rear-ends and i have never looked into the electric ones before. i was just planning on a 9" with the detroit locker. are there any issues with these not disengaging when the power is let off? my friends truck stayed locked all the time and i dont want that in a daily driver? or is the electric locker the way to go? TIA
