Has ford ever made a posi or semi posi rear for it's 10.25 axels, and if so, are they any good and worth the effort to find and buy? I heard that lockright is too weak to handle tough use in the 10.25 and should not be bought, any comments appreciated on these questions.
you want to explain to use what a "semi posi" is. yes they did make a limited slip for these axles as a option.
i dislike the lockrights, but a dustin in his bronco has it in the 10.25 and its held up good to 39's.
