Want to run wheels with a 5x114.3mm bolt pattern on your Ford F-150? These wheel adapters make it possible! This is a set of four, each 1.5 inches (38mm) thick, made from high-grade T6-6061 billet aluminum. They convert your truck's stock 5x135mm bolt pattern to the very common 5x114.3mm (also called 5x4.5"). The studs are M12x1.5 thread, grade 10.9. They have a silver CNC-machined finish. Specifically fit 2001-2004 Ford F-150 models (including Heritage). They are NOT hub-centric (center bore 87.1mm), so proper lug torque and potentially hub-centric rings are important. From top-liftsupport, part number TOP81952701adv, with a 1-year warranty. Allows you to use a huge selection of aftermarket wheels. A must for custom wheel fitment.
