you can use any bolt you want as long as its steel, i wouldn't recommend going down in size though.
No - you can not.
The shock bolts are Metric grade 8.8. Putting fasteners that are graded differently is very bad practice, and may even be dangerous.
Fasteners that are either ungraded, or that are graded lower may not have sufficient tensile strength to withstand the stresses suspension components are exposed to.
Higher grades, such as metric 10.9 or 12.9, may have higher tensile strength ratings, but may be too brittle or too hard for use with the V-Rod frame.
For as long as I've been reading this board, people have been posting uninformed misinformation about fasteners. The engineers who designed the V-Rod specified 8.8 for a reason - and trust me, they know more about fastener engineering than you do.
And, please: Spare us your "I've been using them without any problems" stories. The people who've suffered catastrophic suspension failure because they used Ace Hardware bargain bin fasteners are surprisingly reticent about admitting to their stupidity.
i broken enough shit to know what i can use as a fastener. the ONLY reason manufacturers use GRADE 8 or what ever they choose is because of liabilities. so they don't git there ass sued if some dumb ass can't ride/drive operate what ever the fastener is on......

The OP asked a very simple question: What grade of fasteners are the shock bolts?
To answer this, you really have two options: If you know the (correct) answer. Or just spit out whatever nonsense pops into your head.
Please - just shut up on this subject. You posted bullshit. Quit trying to rationalize it.
