I can't believe this is the first post of this, but I was finally relieved to see a very honest review from people that have thousands of miles in both Gen1 and Gen2 trucks. I really hate TFL and basically every other review of the truck and was excited to get a real off-road review from people that know what they are actually talking about. In summary, the 4-link really does the job and is night and day better. They'll also be the first to know about durability issues with the new 4-link.
