Kit was pretty straightforward.
No drilling is a nice feature.
I will contact tech re install instructions for drivers side...it looked a little offset from the leaf using their instructions.
Results....I put 30lb in after install and got 1 5/8" lift!
Too much for my purposes.
Ride quality was very good. Firm, not harsh.
Understand....Thanks to the quality engineering Toyota is known for, I've been riding on the bumpstops in back for yrs....never knew what rear springs felt like.
I reduced inflation pressure to 10lbs...you could see the rear come down as I released air.
Looks better at 10lb, not a big diff in ride quality.
Loaded truck with me, wife, kid=@400lb total....add shitload of vacation gear, easily another 300lb in the bed....so total 700lb.
Drive over the mountains and back...some bottoming , not as bad as stock.
Return drive was on a Sunday...if a tire store was open, I would have added air....thinking 15lb is about right.
FYI, I ran the airlines into the trailer electrical socket, drilled two holes above that into the flange that it mounts to....pretty clean and out of the way.
If you have a 3leaf rear, I think this airbag idea is the right solution.
