The longer trucks(crew cab long bed) end up with less driveline angle, and normally don't require the driveshaft to be lengthened until you go over 8 inches.

A few things I thought about that I didn't mention earlier are:

1. Dropping the transfer case about an inch will help with driveline angles without causing other problems. The factory spacers that were place above the frame work great when placed between the frame and crossmember.

2. If you go more than 4 inches you will need to fabricate or buy drop brackets for your front sway bar.

3. If your truck still has the factory Y-pipe coming down from the exhaust manifolds, it will cause interferance with the front drive shaft. Sometimes with as little as 4 inches but definitely with 6.
