Best solution for your use case (at the moment) is to not lift your truck. While failures have occurred in non-lifted trucks they are rare.My #2 question was more along the lines, that I don’t want to spend on a 3rd party fix only to have IG come out with a replacement under warranty.
My issue with the alternatives is that my main ‘trip’ is a two hour up and down with high speed (80MPH+ briefly), and a lot if engine braking. When I get to the destination, it is all medium speed and Offroad. The second half seems like it would be fine for the Agile alternative, the first maybe not so much.
