Nasty. Finding the root cause would be good. While there are better lifts/suspensions, I would not call BP-51 a POS (though I understand the frustration when your wife calls and you see what's in the pic). Mine have been installed for almost 50k miles and 5 years with some significant bashing and off road use. I've never had any issues or even adjusted them other than playing with the adjustments. All I do is grease the UCA every oil change. I figure at 50K I'm getting close to rebuild time but I know that going in.
What would go with instead. Mine are getting long in the tooth and I have been thinking of replacing them.Though not as severe as what happened yesterday, I've had my share of issues during ownership. Mostly leaks. Also, one failed shock replaced under warranty, but only after much haggling.
Mine are a very early model. I'd expect improvements have since been made.
Pretty sure I would not buy them again.
