Every Arnott product must start somewhere. With the help of Arnott’s Core Recycling program, engineers examine used air strut cores and determine common failing points. With those in mind, the design work begins. Prototypes are created using 3-D mechanical, computer-aided design software and high-end 3-D printers. Dedicated CNC machines are used to produce working versions of the parts that are vigorously tested on a fleet of company-owned vehicles. Quality and durability are analyzed over thousands of test miles. Once a part passes every test with flying colors, Arnott uses the highest-quality materials (aircraft-quality aluminum, heavy-duty crimping rings, improved seals, premium-brand rubber air sleeves, polyurethan bumpstops) to create the finished product utilizing production machines that are similar to those used to build the working prototype parts.
