I have recently pulled out a GMC Sierra out of the ditch, I gave it a few tugs and my rear end started to slid into the ditch a little bit, the tires that I needed the traction on didn't spin at all and the ones that were just in the slush slop were spinning. I am doing some research on some options for differentials and I don't really want a rear locker but maybe a LSD. Mind you, I have a 95 F150.

1--What would most likely be better? Speed sensitive or Torque sensitive? (I do a bit of driving on dirt roads and things with snow on it, like the lake and back roads)

2--Where can I find these? (I only find them for cars)

Thank you. I'm sure I'll have more questions in the future.

 

you have an 8.8 rear end, correct? Find a factory Traction Lok on ebay, get the ford motorsport clutch rebuild kit, actually two of them and repack the unit per the write-up on modulardepot.com. It wont cost you much to get it setup and off to the installer.

 

Sounds like you may need some lockers. Try looking into Detroit Locker for some ideas. Your wheels should never spin when trying to gain traction and lockers are the way to go. Good luck!

 

What's an 8.8 rear end? Are you talking long box? Yes, I have a long box.

 

The question is if you have the 8.8" differential... which is that round thing that converts the spinning of your drive shaft into the spinning of your tires.

There are different sizes of differentials for various years.

 

Yeah the trac-loc for the 8.8 is mad cheap on Ebay there is one on there right now for 120.

 

I don't know if it's 8.8" how do I check this? Crawl under the truck and measure?

 

look at hte tag on the center section.

for example: It might say 8.8 3 L 73.

In which case, it would be an 8.8 center section with a 3.73:1 Traction Lok diff.

 

Ok, so I'll eventually crawl under there with a brush and take a look.

 

You could get a lock right locker. They are automatic locking and unlocking. They are easy to install in your staock carrier and you will not have to pull the rear ring and pinion so you wont have to set back lash ect. I have run one on my Jeep for years and it has never failed me.

Now it does click when cornering as it disengages and you have to slightly modify your driving style a bit but a locking diff is worth its weight in gold!
