So far so good. Currently with one full practice day and one race day under them. I swapped the piston and rods for the stock Yokomo RO1.0 components. Build quality was good, although I did have one lower spring perch that was not drilled out. And I will be replacing the shock cap o rings because they are slightly too large and start to bunch up when the shock cap is screwed on. Assembly was easy and they fit well on the buggy. They've taken some good hits from other buggies and have not had any issues with leakage or blowing the caps off as of yet. Chassis: Yokomo RO1.0
