twin I-beam
 

What is the best way to level a truck with the I-beam front suspension? And what will it do to the alignment?

you can add spacers to the front springs and it won't hurt the alignment much just change the camber a little and the only way to keep it right is by heating the I-beam up and bending it to the right angle even though it won't wear the tires out any faster if you leave them alone.

thanks, Grindman,
Would you have any pics or examples of what some good homemade spacers might look like?

Maybe you find some answers here: The Ranger Station Technical Library Index - Showing You The Way Since 1999!


there is a section on suspension mods

stay away from the home made spacers though they might work they have a problem of coming out
