I put some doubles in with the C/H swap a few years back. I have about 12K miles since the swap.

Are these still OK or should I dump them for beehives?

 

Aren't the REV's the ones with the bad history of breaking, I would dump them if it were me.

 

A thought batch of REVs had some issues but I got an early run that was heat treated properly.

These pups are very stout. The pressures are a ton more than stock springs. Does this rob power? I'm running a mild street cam without too much lift.

 

You could always have the spring pressures checked....
