Description

The Gorilla Automotive 41188 is a set of acorn bulge lug nuts engineered for superior quality and durability, aiming to set the industry standard for attaching your wheels. Each lug nut features a closed-end design to protect the stud and a conical seat type for a secure fit. These lug nuts are constructed with a chrome-plated finish and have a 3/4" (19mm) hex size, requiring a corresponding socket for installation. The thread pitch is 1/2-20 IN. The product details indicate they are not heat-treated and have an overall length of 1.4 inches. Gorilla Automotive provides a limited warranty for one year from the date of delivery, covering defects in materials or workmanship, provided installation instructions are followed. The product page explicitly states: "You have not specified your vehicle; therefore, we cannot guarantee this product will fit. Please confirm our limited liability for choosing your own wheel options." Therefore, customers must verify compatibility with their specific wheel type before purchase. Additionally, this product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.

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.
