Took little under 3 hour by myself. Gf mom bought me an impact wrench kit for my birthday that I got to use on half of the job, did't get the compressor back from neighbor till half through the job. Purchased 12volt 120psi compressor at Costco to power the bags, too. Pretty sweet, hardest part was drilling four holes on he air bag bracket through the chasis to mount the top bracket.
Already had 12 volt running to the rear for a trailer prior to buying the truck so we can just use that to power the compressor. Also mounted the inlet for air right onto the adaptor for the wire harness for the trailer we use.
Suspensionconnection.com where I bought them. $250 a pair.

sweet!

nice!!

Cool now that you've increased the load capacity of the chassis now you have to increase the load capacity of the tires. You really should increase the tires to a weight rating of at least E. With that extra weight the stock weight rating iirc is D won't hold the extra weight and could blow out.

Sounds good. Yah we only use the boat and trailer, the tongue weight isn't much. And if we do or have thrown some sound or something in there, it isn't going too far,( I hope). Good suggestion though.
