GBA bumpers are made from our proprietary TecsPak® material. Tests have shown that TecsPak® is 10 times more durable than rubber and 20 times more durable than urethane. GBA bumpers are inert and performance is not affected by dirt, oils and other chemicals. Which makes them the ideal bumper for any application involving shock absorption or collision protection. GBA bumpers are perfect for applications where there is a requirement for high load energy absorption with less travel.
