Hi - what is this part called and what does it do?
I have a pair of 2010 Reba xx's - the wiper seal keeps popping so I took apart the air spring and this part is split. I'm not sure it could casue an air leak as it looks more like a bumper?
But I'll need a new one anyway.. The Sram parts list says it should be part of the reba service kit (11.4015.320.000) - but pics of the kit don't show that part..
