    Lift kit was installed today. Took them right at 10 hours to get it done. There was a slight cost over-run due partly due to the fact my alignment was out so bad and partly due to taxes and shop supplies. Effectively 10 hours cost me $160 an hour. So much for $70 an hour shop rate right? But I'm happy with the result and they did a clean job. The kit & misc fittings $900 with labor, taxes, shop supplies costing another $1,600. I was expecting $1,500 best case or $2,000 worst case it ended up $2,500 out the door. They put a suspension gauge in the box so no more $ on cat scales ever again. There were a lot of different ways this could have been set up including all out electronic smart lift or even controlled from inside the cab but I opted for the simplest and cheapest way, a manual lift. So in 10 years time this ought to save a lot of tire wear and maybe even a little fuel. Based off my number the past 3 years the axle should be up in the air about 65% of the time I'm running either empty or loaded. Haven't measured yet but looks like around 3" of actual lift.

    Now you gotta get some kinda plate to cover the front hangers and bags and lines-paint to match buggy and punch a few holes for lights.

    The good thing about doing lift axle now is that you didn't burn up new tire from alignment being so bad .. Probaly recouped some of the cost without knowing it

    Any change in your tare weight?

    Any chance you could add the Speedview app to your smart phone and log some coast-downs with the axles up vs down?

    Alignment is spot on perfect now. Trailer tracks perfectly true. I only put 3,000 miles on the unit dragging it dog legged down the highway. To be perfectly honest I don't really know what the payback is going to be but this modification seemed like a no brainer with all the light stuff I haul plus my empty percentage being so high. And I know for sure I have pissed away $2,500 on much worse things before.

    The kit adds 75 lbs double yellow. Weight savings is not really a concern although 8 aluminum wheels would shave off 264 lbs. Super singles are most definitely out of the question. Not only are my axles not set up for it but from what I am told they don't wear right if you're running 70-75mph which I do a lot. If you keep it around 65 mph or less they are ok. If I have a good year I might pick up some aluminum wheels but for now it's good to go and I'm really looking forward to getting busy out here.

    Speedview app just sounds like more work. I'm set in my ways and have a ledger system that works for me although I will say I have been wondering about trying out profit gauges because I hear so many good things about it.

    Speedview is an app that uses the features in a smart phone to detect changes in acceleration and measure them over time. A more common use would be getting a virtual quarter mile time in your pickup with the smarty jr turned up to 11.

    Glad you went with a Dane. When it comes to dry van I think they are second to none.

    RC, one thing that you will want to keep an eye when that axle is lifted (from the pics looks awfully close to the ground) is when you hit the brakes, that back axle will drop down momentarily far enough to drag the front axle, making flat spots on your tires. I have that problem with my 3 axle trailer when I lift the back axle. The cure is to put an override valve in, then you can air up the back axle to give yourself some clearance.

    that lift looks like it sits pretty low. id think about maybe bumping a extra inch or so into your leveling valve if you can get away with it. it looks like you might skip the ground more than you would like. sometimes its just un avoidable with a lift but you don't want it happening too much or it can skuff your tires up pretty good. although front lifts tend to be a lot better about not skipping than rear lifts witch is part of the reason i suggested a front lift.

    also are you getting un regulated air to your lift bags? and suspension fully raised as far as it can go when lifted?

    Yep. It'll log speed vs time which we could use to determine how much difference lifting an axle makes in RR.
