Timbren or Sumo Super Springs?

Timbrens here on 15 Tundra towing 8K all smiles here..

I have used Timbrens on two trucks and have had good results.

On the other hand, the Timbrens were terrible on my half ton Ram. They caused the ride to be extremely stiff and jarring, even negatively influencing handling. Probably just the wrong product for my light duty application.

I don't have an experience with Super Springs but I really like the Timbrens I put on my truck. No maintenance and no change in the unloaded ride, but they firm things up nicely under load. I think I paid around $200 and the installation couldn't have been easier.
