Description

The Gorilla Automotive K5CS-12125BGR is a set of 20 small diameter spline acorn lug nuts, engineered to provide a secure fit for most aftermarket wheels that require conical seat lug nuts and have narrow lug nut pockets. These lug nuts feature a 12mm x 1.25 thread size and a sleek black finish, with a compatible groove diameter of 0.41 inches. The spline drive requires a specific key (included) for installation and removal, offering added security. The acorn seat type provides a conical base for proper wheel seating. Each lug nut is stamped with its thread size for easy identification and to prevent confusion during installation. The kit includes 20 lug nuts and one 1921SD-KEY spline drive tool. Gorilla Automotive warrants its products to be free from defects in materials or workmanship for a period of 1 (one) year from the date of delivery. Customers are advised to confirm fitment with their specific wheel application, as Gorilla Automotive cannot guarantee fitment without vehicle selection.
