new gears for the 87 thinking 4.56s should i add a locker?

I agree with diesel dawg, a limited slip will be easier on the axle and truck. For street use, it will be fine unless you plan on roasting the 35" tires. Which would grenade a ten bolt anyway.

The factory Gov-Locks use a 100 rpm wheel speed difference to activate. I always found that to be a little harsh and jarring, especially when one tire was on firm ground and the other with no traction at all. A couple times I thought I'd have to sweep up the peices of my rear diff after backing out of a snow bank. In my opinion a selectable locker or strong limited slip would be much better. The Eaton E-locker does both (LS when not activated, locked when active) and will be my choice some day.
