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!
Sounds like its working good for you but what exactly did you install? Dana Spider is a company that makes axles, differentials, ball joints, u-joints and several other driveline parts.

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.
So you got a limited slip, that makes sense now. I had one of those in my Jeep before I swapped it out for a locker. Good unit for a 2wd street truck.
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.

Yeah the track lock uses clutches to keep both wheels spinning at the same speed but still allows some slip so you can corner without chirping the tires, those clutches will wear out and need replaced eventually. There is also gear driven limited slips like the Truetrac, no clutches to wear out but they also cost more.
