2019 tacoma trd offroad. If you buy 2" blocks or less you will probably need to grind 1/8" of the cylinder rack mounting bolts, this is nowhere in the instructions and will be a big problem for those who don't have a grinder or don't want me mess around with a new one. Definitely an annoyance. Otherwise these are fine. Just a block of metal. The only other way to mess things up would be threads. They're ok, not great, but good.
