Use of ABS Plastic

Please note that although all our precision-made ABS accessories are extremely strong and durable, they do not hold the same shatterproof label as our 10mm thick polyethylene composite splitters. The accessories are manufactured in ABS with the intention that they will be lighter, bolt-on attachments that will improve aesthetics and are easily replaceable if they become damaged from varying road conditions.
