What leafs do you guys use?

The passenger side is set up like that for power transfer. Most power is applied to the passenger side, therefore the stiffer spring to plant the power. Similar concept to a traction bar, I know how they work just didn't think they would ever do that to a car from the factory.
thats the word I was looking for power transfer. ya you know what you're talking about. i'm just a young guy who knows how to research n the internet and in books. lol. and from what i've read yah they came on cars with 340's. hopefully you get any problems that you might have with your springs fixed though. i don't think the wheels should sit further forward on either side
