As Mike mentioned, new dropped springs are not going to yield a full drop as advertised. For example your stock springs have lost tension over the years and are already allowing the truck to sit about an inch lower than it did from the factory.

I personally wouldn't run more than a 3" drop spring in the front.. it will make it pretty difficult to get the alignment back in spec.

So, 3 in drop spring will net only about a 2 or 2.25" drop over where you are right now. Realistically speaking your truck will sit about 31" in that same place you're measuring from.

If you decide to add discs up front I would suggest dropped spindles. And maybe a combination of drop spindles and drop springs to really get it down .. dropped spindles will give you 100% of the advertised net drop. 2.5" spindles gives you your 2.5" drop AND you can retain the factory ride, steering geometry, and alignment specs. Go with spindles if you can.. you'll be glad you did.
