315's with a leveling kit??
 

Couple of Questions:
1st I just purchased a 2.5" Daystar Leveling Kit and I was wondering if I should upgrade my shocks for a better ride and is this a good kit?

2nd Could I fit 315's with just the 2.5" kit or would I need to add a body lift?
Do they have 2" body lifts for '05 F150?

Welcome to the site. No, I don't believe anyone makes a 2 inch body lift for the 04-06 F-150's. Yes, you can fit 315/70-17's (35x12.50) on your truck, if it is a 4x4 and you use the OEM 17x7.5 inch wheels. Also, if you want to upgrade shocks, I'd suggest the new Rancho's. They have a threaded shock body (the front's) that allow you to adjust the ride height and eliminate the need for leveling kits.

You mentioned "adjust the ride height". Don't you mean adjust the ride quality? I have not heard that Rancho shocks can give you any kind of lift but sure would be interested as I have a set of Bilsteins and an Autospring 2" sitting in the garage waiting install.

Thanks.

I think he means u can adjust the shocks if u lift your truck
