The Gorilla Automotive Products 21631SD offers a robust solution for protecting your wheels against theft. This set includes four small diameter wheel locks, each designed with a spline acorn hex head and a closed-end construction for enhanced security. The locks are triple nickel chrome plated for a durable, attractive finish and are heat-treated to improve their overall strength and longevity. Each lock in the 21631SD set features a 60-degree conical seat, a standard for many aftermarket wheels, and a thread pitch of M12-1.50 MM. The overall length of each lock is 1.36 inches. This kit comes complete with one dual hex key, compatible with both 3/4" (19mm) and 13/16" (21mm) sockets, ensuring ease of installation and removal for the user while deterring potential thieves. Gorilla Automotive has been a leader in wheel security since 1976, known for its quality, durability, and theft-resistant designs. Customers are advised to verify compatibility before purchase, as the manufacturer provides a limited warranty that may be voided by improper installation or non-compliance with fitting instructions.
