Timbrens or SumoSprings?

[KOZ45]

Thinking also about payload and/or towing assistance with this truck

My F150 had the Max Tow with Timbrens and the truck was able to handle 2500 pounds in the bed

This Silverado seems to squat easy and it needs some help...…….I like Timbrens because they are simple and effective

I saw another product called SumoSprings……….anyone have hands on experience with them?

Air bags are appealing but seems like the bags and lines are more prone to leaks and failing...…....and the need for an air source
