Is this differential arrestor (55425-N4300) spent?

It doesn’t look too bad, but it’s a little stiff and there is a tiny bit of wear near where the bolts are. Debating whether to replace it while the diff is off. 

I've only read about them breaking for the guys that have V8's and abuse them.

That one looks to be in excellent condition, I would say it has had an easy life so far.

Thanks guys! Didn't want to throwaway good parts if not necessary. 

use it again! no problemo

Or ditch it for a RT Mount and fix the less than optimal design.
