Spend a little extra and get the McGaughy spindle and keep the stock springs. You won't be sorry! DO NOT BUY BELL TECH SPINDLES!!!!! They are horrible. You will end up with twitchy steering and severe bump steer issues.
If you can't afford the McGaughy spindle just put a 2" spring in the front. Just the springs aren't as good, but they aren't bad either.
Good Luck!
It will look really good with the drop kit on it.
