  • Q:

    How exactly does this locker engage? I am looking for a locker that will not engage on the road to prevent tire wear and dangerous turning. If this locker does engage on the road, are those concerns addressed? Thank you.

      Hello Devin, the Detroit Locker Toyota 8.4in. Automatic Locker part# EAT187SL199A engages whenever your foot is on the accelerator. This can make highway driving a bit trick. You will need to let of the pedal around corners so that it will unlock and not break traction. Thank you for your inquiry.

      Hi Cowtaquito
      This locker will fit your Tacoma You will not require any other components but a install kit would make the install much easier because you will have all the necessary bearings and shims encase you damage the originals. http://jo.my/sqm0qy Thank You
