NX419 shocks
https://nexxracing.com/product/nx412...

Pros: Super wellconstructed and none of them leaked fluid. The NX419 are a super versatile shock. I think overall the best bang for the buck is the NX419 shocks. Both sets of shocks fit perfectly and there is no slop in the pivot balls.

Cons. One of the pivot balls in the shock cap of the NX419 shocks was falling out and that pair also came without preload collars. No big deal as the collars from the other shocks fit perfectly and I was able to run the shocks. The shock shafts bending on the NX419 was most likely due to driving at a skate park.
