If Ford had a 'track pack' brake option, it would be easily 5k. I suspect that is why they don't offer it, that'd push some of these trucks to like 80k with tax.
I would like the Alcon kit so I can keep factory wheels, all tolled, it would be about 8k installed, so luckily for me, I only need another 8k and I'm good to go.
We do offer financing if you'd like to explore that option! And if you're relatively mechanically inclined, the kit can be installed in an afternoon in your driveway with hand tools.
