The T-Bone bupers are heavier than the stocker or RPM bumper. I don't have mine with me at the moment, and no pix either
The bigger T-Bone bumper that Alfred had on his 18T might be close to double the weight of the stocker, and just a little more than the RPM. It's probably due to being made from Delrin. This also makes them stronger and more resiliant. BUt not indestructable
I mention that Alfred has the bigger 18T bumper because T-Bone Racing also issued a smaller, more compact version 18T bumper. That one is not as wide, but still offers alot more coverage than the stocker. Less chances of hooking something like with the wider T-Bone and RPM bumpers
. It is geared more toward racing applications.
I've currently got that one on the front of mine, and the rear T-Bone issued bumper "just in case"
. I find it just right for the on-road duties I have it set-up for
