Installed Dana Spicer
This is my first post, but I've been reading for a while. Decided to replace my open differential with a Dana Spicer and I can't say enough about this swap. I get excellent traction on snow and icy roads. Almost feels like I'm riding in a tank. My truck is a 2wd, so I'm use to doing a lot of spinning with little to no traction. Anyone considering this upgrade should go for it!

I was running a stock 3.92 gear, but when down to a 3.55. Most people will cringe when they hear this, but I do highway driving and seldom tow. I'm hoping to gain a couple of extra miles per gallon. I can already tell that I'm getting better mpg and lower rpm's on the highway. Haven't crunched any numbers yet on milage, but will in coming weeks.

This differential is a Trac Loc model. It's like a positive traction rear end. Both tires push all the time, but it has the ability to allow one wheel to slip when needed while keeping power to the other wheel. Then power returns to both wheels. I think some limited slips operate a little different.
