Re: Leveling coils?
As far as the OffRoad springs go, they are NOT taller; they have the same uncompressed height as the regular 1500s, but after installation, they make the front end of the 1500 sit higher because they compress less (stiffer).
I personally like the way the Off Road coils feel on & off road better than the regular coils.
2500 coils are really not a good idea, as they are either too stiff (not a good thing for off-roading, but better for towing/hauling) or actually softer than stock 1500 coils.
Finally, make sure that you get Off Road Quad Cab coils if your regular 1500 is a Quad Cab & Off Road Regular Cab coils if you have a Regular Cab. The driver's side coil is always thicker than the passenger side coil (they are not always tagged or marked).
You don't have to compress the Off Road coils as they are the same free height-just drop the front diff & replace them, and get an alignment + align your headlights.
Good luck, keep us posted.
