I'm just resetting my front wheels to be straight, I only have 8 turns of the tie rod onto the steering arm, factory preset was 10 (late model rack untouched).
Is this enough or should I look for a new longer tie rod end?
Thanks.

8 turns engagement is plenty, IMO.
There are only 6 threads inside the lock nut, and they don't strip.
