Popping behind !

well, if you don't constantly do pavement ripping burn outs it may last a lifetime. then again how can you not. 8.75 can go for at least 150,000. but i dont go that long between services. 30,000 sounds about right. my 7.25 has 218,000. i bought all the seals and bearings for the massive rebuild a couple weeks ago. the last major project left on the car. EVERYTHING else is new.
