What's the best brand for rear air ride shocks for 07 tahoe ltz? Must have good towing power

 

Factory shocks. They work the best with the auto ride system. I've done mine in my '11. Yours have lasted 15 years.
It's only a 1500 series truck so there is nothing that will make a 2500 truck towing wise.
I tow a lot also, have 5 trailers.
