3.4 Dogbones

Got a 91 Z, and i'm goin through 1 "torque strut" ie. dogbone every 6-8 months. I know i drive hard, lot of light to light heavy foot'n. I'm just curious as to the length of others mount life. As well as if the FFP dogbone is worth the money.

I just replaced the motor not that long ago. As well as a rebuilt and strengthened cradle. All the mounts are and very good condition. That is why i can't figure out why i'm killing these things so fast. I mean i just replaced it yesterday. Thats the 5th one i've done in about 2 yrs. Had the same issue before the motor change.

Strut type?....It's not a "strut".....It's the regular Solid dogbone with rubber bushings and steel inserts. When i said Torque strut, that's because that's what the technical term is. I didnt mean a shock/strut style mount. 1 thing i forgot to mention almost 100% of the time its the motor side bushing that fails not the rad. side.

Maybe I read it wrong then. The rubber bushing are more than likely the problem. They dont last long, especially when your driving your car hard. Try some polyurethane bushings. Because when your driving your car hard, the engine moves alot, especially with the rubber bushings. So that just maybe be your problem. Or maybe it would be something is bent so its like a "wrong" force if you will because something is not alined right.

beatin the shit out of.......and driving hard are 2 things in my eyes. I mean i drive it hard no doubt. I mean i do occasionally race from a dig as well as a roll, but lately its few and far between. I'm probably just gonna pick up the FFP 'bone the next time and not deal with this. Thanx guys
