Very easy. I had to file/ grind the end of the internal bar weight flat (has a half moon protrusion to fit the factory end caps). Other than that it just bolts in place of the original end caps. And filing the half moons off doesn’t prevent you from reinstalling the factory caps if you want to go back to them in the future.I've been thinking about doing the same, would be nice to be able to give the old paw a break on the highway sometimes. Pretty easy install?
