T25 Upper spring packing for the top of the spring.
These are the previously unavailable original style pieces.
Volkswagen superceded these with the steel reinforced VW T4 style packing pieces
in the 1990s and the original all rubber versions haven't been available since.
Exclusive BUS-ok Production, that means high quality
as the genuine part.
This is not a f*ing part from an 3D-Printer.
OEM part number 251-511-149
