I replaced mine two nights ago and used the suggested (thanks CC) grade 8 with nylock nuts. Look identical to the bolts and nuts supplied with my new front endlink kit from Energy Suspension.
It is my firm belief.....that for the most part...
..... factory spec, is just a way to keep sales proprietary, and generate factory revenue.
Sure! There are other things like O2 sensors that crap out on certain vehicles...
But a bolt?? ?? If it does the job...... IT DOES THE JOB!
I get a kick out of the requirement for aircraft to use "aircraft bolts"
They are steel.... they have a tensile strength four or more times
and a shear strength 10 times that of the aluminum material that hold together!
and a price to match!
Yet.... warplanes have been made of wood,nails and horse glue, with a cloth skin.....
and have lasted almost 90 years (WWI aircraft) and can still be flown!
Oh ! And, if you build a copy of one of these warplanes...
you are required to use "Aircraft bolts"!
