Linked suspension systems.
What is the proper size bolts to use for connecting control arms to the chassis / axle?
Obviously a race car or bouncer needs massive bolts to match their application. What is needed for the rest of the vehicles out there on the trail?
Myself I feel like a 5/8" or 16mm is the smallest I"m comfortable with on a lower link. I think using a 3/4 or 18MM offers a bit more confidence for resisting breaking from impact to a link from landing on or hitting a rock.
What about upper links? They should never see impact forces. So how small is too small?
9/16 or 14mm is the smallest for uppers in my opinion.
What about the upper link in a 3 link? Is 9/16 or 14mm enough then?
Bushing type suspension joints would cushion the mounting hardware a bit but for this discussion let's focus on hiems or uni-balls.
How small can you go to save weight before it compromises durability or potential failure?
If you have had a link / control arm bolt failure please chime in!
