Before ordering

Match the full SKU, dimensions, thread or bore size, finish, vehicle application and pack quantity to the intended installation. Where an application is vehicle-specific, confirm model year, engine, transmission, body style and any stated exclusions. Universal does not mean suitable for every installation; available space, interfaces and supporting components still require checking.

Installation and use

Follow current manufacturer and vehicle service information. Performance, braking, suspension, fuel, steering and safety-related components should be installed and checked by a suitably experienced person. Confirm required companion parts, settings, clearances and local road-use requirements before installation.
