When I recently hooked my small boat up to the Sienna I noticed that the rear end dropped more that I remember it dropping in the past. Is this an indication of something worn (shocks, springs etc.)? Can any bolt on modifications help prevent this drop? Any help is appreciated.

I installed Airlift 1000 air bags in the rear springs on my 2003 Sienna.
A link to the first in a series of pictures......that show the installation process.

NOTE!!!
This does NOT increase the loading capacity of your vehicle.....
The intent of the Airlift 1000 is to maintain the original ride height when the vehicle is loaded.
They do work very well for this.
You add air when you increase the load......and let air out when you don't have a load.
Minimum air pressure to be kept in them is 5 pounds.
Max air pressure to be put in them is 35 pounds.
I use a bicycle pump to adjust the air pressure in them......only takes a few pumps to add air needed.

Thanks for the help! Your pictures of the install were a great help. I will order the kit for the install soon.
