I'm looking to putting bags on my 54 p/u and I'm pulling my hair out. There's actually to much info out there. I just want to raise and lower my truck, not play with it. I was wondering if the 1/4 under the dash set ups are going to be strong enough? I don't care about speed. I have re7 slam bags if that matters. Also if that wont work what would be good valves to go with?
