I'd opt for the most rigid option. Water just pools there and corrodes whatever you have - so even with any sieze mine have been a bitch to remove more than I care to admit.
Got it,those don’t look large diameter enough,but I guess it’s a see in person thing,right now I’m stuck with the rear air lift bags,so I’m only using a small energy studded bump on top.but when we get rid of the rtt and start towing,I will use these rock jock bumps.
