    How about the lifetime and service of the kit?

    The kits have been proven on street and track applications by hundreds of our customers. We're constantly doing R&D to make the kits even better, all improvements are based on customer feedback which is very important to us.
    We have proven the very same bearings with no maintenance for 20,000 kilometers, through the year, in daily use without signs of excessive wear. When the bearing life comes to an end, they're easily replaceable! Bearings are available around the world from automotive and industrial dealers and any of the spare parts can be also bought separately from us.

    We want to keep our customers 100% happy thus we're only using the best materials and manufacturing processes available. All parts are CNC machined: highest quality CrMo tool steel is used on the adjuster parts which are zinc plated for best corrosion resistance, welding is made easy with high tensile structural steel and small spacers/adapters used on the kits are 304 stainless steel.

    We use DHL Express shipping for all items. Please find your order tracking information from DHL website.
