Great tracking on shipping. Brought the parts over to a local shop who installed without a problem. Makes the van feel a lot more stable.

Definitely helped with the sway, and increased the ride height about an inch.
Ride seems to be as good as before.

Super easy to install, I removed the wheel for easier access. Installing the SumoSprings was easier than taking the wheel off.

Purchased front and rear Sumo Springs to help stabilize the ride, outstanding results. Installed in less than 2 hours.

Can feel the difference just backing out of the driveway going over the concrete rain gutter as well as when taking turns. The van does not sway as much. Looking forward to our next camping adventure with the van loaded down.
