And I was just curious why rhagfo made the comment about band aids when he has some mods on his OWN truck.
I've used drill kit bags on a truck and I mounted them so the axle would bottom out on the rubber stops before the bags smashed completely. My 03 has the bags that replace the rubber stops and the bags would bottom out until I modded the brackets to give the bags more travel.
The bumpers inside the bags would be a waste of money if they aren't needed but I don't know if you can get enough info (dimensions) from the mfgr to determine if you need them before buying them and seeing for yourself.
After having both kinds... if I had the choice, and that depends on the truck application, between a drill and a no-drill kit, I would MUCH rather have the drill kit. If a no-drill kit that replaces the rubber stops is your only choice, I would say you probably can't go wrong with the internal stops. Craig
