You've really done a ton of work on your truck, and it sure shows. Seems like you really like that OME rear leaf pack. I have the same model/year truck as yours, except it's an access cab. Did you have any problems with driveline vibrations at all? I had an 8-pack Alcan setup in the rear and DR coilovers in the front. Still have the coilovers, but ditched the Alcans and went with the Toyota TSB 4-leaf pack for now. I had too many driveline vibration issues with the Alcans, and couldn't get it straightened out to my satisfaction, so that's why I changed for now. Some people have them, some don't. However, the OME's would certainly fit the bill for what I want to do.
