Fuel economy will not be affected much unless there is a lot of highway driving and at a higher speed where aerodynamic comes into play.

Most of this was averaging 100kph (62mph) on major country roads, not divided highway.

 

I want to put a lift on my van. Can you suggest places to have this done?

 

You should check the thread on the Mods and Projects page. They discuss some places in the US to get the kit installed.

 

How did the lift affect how the van behaves. Any changes in the driving dynamics?

 

Honestly, I haven’t noticed much. It’s still lower than my wife’s Subaru Outback and seems to handle fine.

My last tank had more highway speed driving, and was 6.2l/100k, so fuel efficiency on par with pre-lift figures. Prior tank was 6.0, best I ever recorded. Prior to that was 6.1, so not a fluke.

Maybe you lose 5% max at higher speeds.

I saw a Sienna last week with what must have been a pretty good load- looked like it was almost scraping the ground.

Very happy with my 2” lift. Without it I wouldn’t make it out our driveway in winter, or some of the canoe-access roads we drive without some big impacts.

 

Good test for the lift kit- we barely made it out an unplowed country driveway with knee-deep powder. Unlifted van would have high-watered like a beached whale.

 

Great info in this post OP! Trying to decide what to buy for cross country travel. Looking for fuel economy, space for the dog and sleeping, and ability to get up a forest road. Thinking the lifted sienna is top of the list!
