I have the JourneysOffRoad 3.5-inch lift kit on my 05 XLE AWD. Purchased in early March 2019 and had the kit installed by my mechanic March 20, 2019.
Definitely improved my ground clearance. I pretty regularly drive Forest Service, BLM and farm roads of widely varying quality. Some of the Forest Service roads will shake you fillings out if you drive over 5MPH. Some of the FS roads are deeply rutted. I haven't scraped bottom or come close to high centering with the kit. With the lift I can get many places that I would not be able to otherwise. My Sienna is a daily driver and a road trip/vacation vehicle. I live in Concord CA and drive extensively. Shortly after the lift kit installation, I drove to the Great Slave Lake in the Northwest Territories with no problems (approx. 5K miles).
The kit is very solid and quite well made. One could put the kit on at home with some serious jacks and jackstands. It would take a full day, maybe more.
JourneysOffRoad was very willing to answer all my questions during my pre-purchase investigation. I am very satisfied with their kit and their customer service.
I first put Yokohama Geolander 235/65 R17's on my stock rims. They seemed fine. I wanted to run Bridgestone Duelers after the kit was installed. I have them on my Tundra 4x4 and really like them: good off-road traction, quiet on the highway and they last about 80,000 miles. Unfortunately the smallest Dueler size rubs the spring collar on the front suspension. Thus the switch to the Geolanders. I now have Toyo Open Country AT II 225/65 R17's on the van. The Toyos seem to have better traction on dirt than the Geolanders
I have driven a bit over 40,000 miles with the lift kit and the tires. I am quite pleased with the setup. The van handles fine both on and off the pavement. It corners well, brakes fine, and doesn’t feel "tippy" at all. The added height was a notable change when getting in and out at first, but I adjusted quickly. I have not had any problems with the CV joints, boots, alignment or handling.
The only drawback is the scratched paint from driving down Forest Service roads that are overgrown with brush.
