Rear Differential
 

:moon::choochoo:Am getting ready to rebuild a GM 12 bolt. Wanna get more traction.

Looking at either a locker or spool. spools are a lot cheaper than lockers truck won't be a daily driver. Occasional trail/mud and truck pulls. Maybe a little cruising around town.

Anybody have any experiences with a spool around town? Is it worth the money to buy the locker instead?

Thank You!
