Includes 2007 Classic models, some parts cross over to the SUV's but they are listed on their own page.
The suspension in these trucks was only slightly changed from the previous generation. But the change was significant enough that the 2WD and 4WD now used the same knuckles. Oh, and did you see I now called them "knuckles" instead of spindles? That's because the hub now is removable. You can still lower them with a coil if it's a 2WD. The 4WD models used torsion bars which can be adjusted for a bit of a drop or indexing keys replaced for about 2 inches of lowering. Although I have personally never seen one, there are apparently some 2005-06 model 2WD trucks that also use torsion bars instead of coils, same as the SUV's.
