Show original supplier description
The Gorilla Automotive Products 78421N is a set of four open-end acorn wheel locks, designed to provide security for your vehicle's wheels. These locks feature a unique external security pattern, offering an effective deterrent against wheel theft and protecting your valuable wheels from unauthorized removal. With a thread size of 12mm x 1.25 and a conical seat style, these locks are engineered for a secure fit. The overall length is 0.875 inches, and they utilize a 3/4" (19mm) hex size for installation and removal. The zinc finish provides a degree of corrosion resistance. This kit includes four locks and one matching key, making it a straightforward solution for securing one wheel (four-lug pattern).

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
