2003 7.3 PS Cargo Van LSD options?
I've searched the web and different manufacturers and could use some advice from the wise folks here.
I have the 7.3 powerstroke 2003 model, essentially stock outside of DP tuner and fuel recirc mods.
I'm looking for more traction when towing, but I'm having a really hard time navigating the aftermarket options.
There are air lockers, electric lockers, friction plate, gear driven, and "ratcheting" types, compounding that it seems that Ford put any one of several rear ends in their vans at any one time.
I've contacted a couple companies and they ask me what "spline" I have.. how would I know that? (sorry for being ignorant on this).
I could use some help and advice.
I was hoping for a lower cost option because the van is a 3rd vehicle. I wouldn't mind a locking differential but I sent some emails and it seems that only air or electric lockers are available.
What do you folks recommend?
