I have been looking on the interweb for an 8" factory E-locker and I am wondering what a reasonable price is for one. Specifically, I have been looking for a Tacoma or FJ 8" with the 3.73 gear to match my stock front gear.
Look for an 8.2 axle with locker from an auto FJ or 4Runner 10+. Will upgrade your ring and pinion strength as well. I have seen them used for $1200-2000.
