Fox 2.5 DSC 13x600 to 14x650?

Recently changed 13x600 springs to 14x650 to accommodate a slight weight increase up front with ride heights being the same as before. Now it feels as if rebound is insanely fast when I go over bumps or any type of rapid change of road height ie potholes, tall speed bumps, etc

Will 50lbs extra rate increase cause that much a change?

 

In short, yes. Valving will also play a part in controlling the shock with what ever spring rate is on there.

Great article we have that discusses spring rates for Tacomas:
