Fastener Question

[gbrsand]

What grade fasteners is everyone using for suspension and shock mounts? New car has all grade 8 and after pics of upside down car from broken bolt on GD.com going to change all the bolts in this car this winter, trying to decide if F911 grade 9 is the way to go or is new grade 8 adequate. Have seen pros and cons for the F911's some say to brittle heads pop off so what say DDR? Thanks for any input GR

I have all grade 8 bolts in my tatum. I have jumped it 20ft high. Never any issues with the bolts. You will probably have more cracking issues with the chromoly frame. Just my 2 cents.. Grade 8 is fine.

Ok thanks Denbt oy. I was thinking Grade 8 would be good but wanted other input to be sure. Thanks again

Never heard of needing much more than grade 8. Now that I think of it though, my rear shock upper bolts are a higher grade but it could be because they are longer and go all the way into the X brace of the cage.

even the long bolts on shock mounts are grade 8 just wanting to make sure we don't break one, bad things can happen if you do.

My car has nothing but grade 8. I have a 4 seat S&S and let me tell u I've never had a bolt break. 

 

Grade 8 will be fine
