Ive heard of lots of guys liking the VP and the s&b intake actually so id have to say good choice
lol ive never used them though. i have a Bakflip HD and i love it.
for the levelling kit, it depends on how much you want to spend, I put in a 2.5inch hellbent steel levelling kit, it was only $80 and works great, and you can easily do it yourself, and once you get it on just get an alignment.
Or if you want to spend a few more bucks you could get bilstein height adjustable shocks, they will run you a couple hundred (if you can find em in stock) and then you can either do em yourself by buying/renting/borrowing a shock compressor or have a shop do it.
Ive heard that you can just take out your strut into like canadian tire and they have a shock compressor and for $80 or something they have put the new shock into the strut, and give it back to you, but that im not to sure of,
