As you can see in my signature I have a 2wd truck but it only has 42K on it and it is in like new condition. Honestly I would love to get a 2009 or up f150 supercrew 4wd used but the idea of paying 20K plus for a truck with over a 100K miles on it is not really appealing to me. I drive a work van so I only put 5K or so a year. As I am sure most if you know a 2wd drive with empty bed and huge motor in front is not real useful in slick conditions so I am thinking of installing a locker as well as some more aggressive tires on the rear to help. Not talking going mudding but this thing will get stuck in wet grass. Just looking for opinions on it the install is worth the money.
For on the street you are most likely better off something like the Detroit Truetrac. A good rear differential can make a big difference in traction. The stock limited slip leaves a lot to be desired.
I had a limited slip in the 2000 expy I had before this and it did well. It was 4wd too. I just figured if I was gonna spend the money I should get as many opinions as possible first.
I would second the post above about the truetrac. Those are great units. I'd go with an aftermarket limited slip, witch are way better than the stock lsd. You can get them with full lockup capability too. I run the auburn exted locker in my wheeling jeep and I seldom use the lock feature, even when heavy wheeling. The lsd in it is amazing. That would be an amazing unit in the trucks. Would love to put that in my f450, but don't think they make it for that.
Also, I second the comment on the friction modifier. This is a must. Also, most of the units don't like synthetic. Just run the standard gear oil.
You can throw an auto-locker in it, such as a Detroit or Yukon Grizzly, or a selectable locker (preferred but more expensive) like the ARB air locker. Any such option is a major and expensive undertaking. You'll need an axle master overhaul kit, new gears, someone to set those gears up for you, and air pumps if it's an ARB. Though if for some reason you were looking to regear the rear end, well, then I guess you get both birds with one stone. The difference in traction when you need it is phenomenal, even with street tires.
