This 32-piece M14x1.5 spike lug nut set is designed for compatible 8-lug trucks and SUVs with aftermarket wheels using a 60-degree conical seat. Each assembled lug nut measures 5 inches (127 mm) long and 0.9 inch (23 mm) wide, creating an extra-large red spike profile for a bold custom wheel appearance. The 2.16-inch carbon steel lug nut body supports secure thread engagement and dependable wheel fastening when installed to the specified torque. A removable 2.83-inch spike tip made from lightweight 6061-T6 aluminum adds visual impact without unnecessary steel weight. The two-piece design allows the lug nut body and decorative spike to be installed separately, helping simplify tightening and reduce the risk of damaging the spike finish. Black and red electrophoretic coatings help protect the surfaces from moisture, road salt, and everyday corrosion, and both finishes have passed a 72-hour salt spray test. The package includes 32 lug nut bodies, 32 removable spike tips, a dedicated installation socket, and a wrench. Compatible applications include select Chevrolet Silverado 2500HD and 3500HD, GMC Sierra 2500HD and 3500HD, Ford F-250 and F-350 Super Duty, Ram 2500 and 3500, Express, Savana, Suburban 2500, Yukon XL 2500, and Excursion models. Verify M14x1.5 threads, 60-degree conical seats, 8-lug quantity, wheel recess clearance, and exact year fitment before purchase. Some Ford applications use M14x2.0 threads and are not compatible.
