I want to ask here before wasting my money. I have a 2.5" spacer in the front which still leaves me with about 1" of rake. I'd like to install the Bilstein 5100's up front to remove the additional rake and possibly in the rear as well.

Can I install the Blistein 5100's and leave the 2.5" space in? Could I get a bigger block in the rear for an additional inch of height all around?

These are what I'm thinking- https://www.stage3motorsports.com/24...nt-Shocks.html

 

The only way you can do both in front is to leave the Bilsteins on the stock (lowest) setting. Some people do that for a softer ride because the Bilsteins ride pretty firm on the highest setting.
You're maxed out now with 2.5" spacers. Your angles are probably pretty ugly as is with 2.5". Sounds like you need to save your pennies for a 4" or 6" suspension lift.

 

Agreed. Get a proper lift or just leave it as is. You could also ditch the spacer and set the Bilsteins on the highest setting and see where that gets you. I would do the Bilsteins in the rear as well. Stage 3 sells a kit with both for about $100 more.

As I’ve already stated in the multiple threads you’ve started about getting your truck perfectly level, I think it looks great as is and even better now that you’ve got the new tires on. Going higher in the front without an actual lift is probably a bad idea.
