gbrsand Posted December 16, 2016 Share Posted December 16, 2016 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 Quote Link to comment Share on other sites More sharing options...
Dent boy Posted December 16, 2016 Share Posted December 16, 2016 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. 1 Quote Link to comment Share on other sites More sharing options...

dunefreak Posted December 17, 2016 Share Posted December 17, 2016 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.

gbrsand Posted December 17, 2016 Author Share Posted December 17, 2016 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. Quote Link to comment Share on other sites More sharing options...
