I purchased the blue rear sumo springs for my Toyota Tundra to help out with towing a 30-ft toy hauler. Loaded down max weight is 8800 lb. My max truck tow capacity is 9800. Even with a weight distribution hit it’s still squatted down too much. With the sumo springs it tows very smooth. Minimal sag, easy installation.
I contacted customer support since there was an error on my part of entering the ZIP code and didn’t look like they shipped to Alaska. I thought that strange since it said international Sumo Springs.
Customer service was prompt and assured me they did ship to Alaska. With a discount code my shipping cost was only a few dollars.

I give my purchase a 10/10 as products work as specified which is great. The front kit is great on and off road acting as bump stops. However, the rear is really stiff(airless airbag as advertised) which is great for road control and anti towing sag. Not so good off road though. Would be nice if there was a kit for the rear to act more as a bump stops instead of airless bags. Both kits are fairly easy to install with only a couple tools. Kits seem to be universal fit so some bolt cutting on front springs may be required depending on your application.
