Note for Australian and European Markets

Unless otherwise stated, this product may be engineered for use in Left-Hand Drive vehicles. Steering components, pedals, shifters, linkages, wing mirrors, instrument clusters, panhard rods/traction bars, drag links, brake boosters, brake or clutch lines, accelerator cables, heater cores, some master cylinders and adjacent parts can vary between LHD and RHD configurations. In some models compenents such as windscreen wiper arms, motors and linkages could differ in their size and orientation. Items such as floor mats & dash mats may have differences in their structure around the front row (or padding in different locations). In many cases items are identical depending on the design of the vehicle and part, but may have differing mounts, lengths or bolt patterns. Carefully review the product images and details to ensure suitability for your vehicle, or contact StreetFX support if you are unsure. Returns are not accepted for special order products.

Important Note Regarding Nitrous & Pressurised Systems

Orders containing nitrous systems or other pressurised canisters may require additional handling and inspection prior to dispatch.

Due to the nature of these products and applicable transport and state regulations, each system is individually inspected, released, and purged where required to ensure compliance with air and road freight standards. While most orders ship within our normal timeframes, this process may occasionally result in slightly longer dispatch times than those advertised.

We do everything we can to minimise delays, and the vast majority of shipments move through without issue. If you are working to a tight deadline or require urgent delivery, please contact us prior to placing your order so we can confirm the most suitable options.

We appreciate your understanding and patience - this process ensures safe, compliant transport and delivery of your order.

Special Note for Dodge Ram (Classic/DT/DS)

Since Dodge/Ram manufacturered concurrent Ram 1500, 2500 & 3500 models on both new and old body designs, please ensure you select the parts to suit the correct submodel. The year alone may not always be a reliable way to verify your submodel in the case of some Rams, so we encourage you to double check if you have the Classic, or the new shape when making orders for parts that are not the identical between both styles.

Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase. For assistance or clarification, please contact customer support.
