How Strong Are Our Splitters?
HOW IS YOUR SPLITTER SO STRONG?
Each splitter is developed to become an integral part of your stock body kit, giving it unrivalled rigidity and strength so it can absorb scrapes and protect your bumper.
WHY DO YOU USE POLYETHYLENE COMPOSITE FOR YOUR PRODUCTS?
Strong, impact-resistant, doesn't corrode or chip, and has excellent abrasion resistance (eg. scraping on driveways!)
WHAT ABOUT CARBON FIBRE?
As strong and light as carbon fibre is, it cracks on impact or when under load and/or stress. Clearcoat can eventually fade or crack, becoming undesirable.
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.
