Hopkins

<p>Founded in 1953 in Emporia, Kansas, Hopkins Manufacturing Corporation has grown from a single-product company into a globally recognized leader in towing electrical products and automotive accessories. For over 70 years, Hopkins has built its reputation on innovation, quality, and a deep understanding of what vehicle owners need when it comes to towing, hauling, and maintaining their cars, trucks, and RVs.</p><h3>Industry Leadership in Towing Solutions</h3><p>Hopkins Towing Solutions is recognized as the automotive industry's leader in towing electrical products, with more than 40% of retail-category sales generated from Hopkins innovations and 9 out of 10 consumers relying on a Hopkins wiring product solution for towing. The company's mission centers on making the towing experience simpler and more rewarding through continuous product innovation. From vehicle-specific wiring harnesses and <a href="/1610-hopkins-electronic-brake-control-relay-3316">electronic brake control relays</a> to <a href="/1610-hopkins-trailer-hitch-1212">trailer hitches</a> and backup camera systems, Hopkins provides comprehensive solutions for anyone who tows recreational vehicles, work trailers, boats, or cargo.</p><h3>Comprehensive Towing Product Range</h3><p>The Hopkins product portfolio spans every aspect of the towing experience. Their offerings include trailer wiring harnesses, connectors, adapters, brake controllers, trailer break-away kits, and rear view camera systems. What sets Hopkins apart is their focus on ease of installation and user-friendly design. Hopkins brake controls are equipped with Plug-In Simple® connectors that are guaranteed to reduce installation time while preventing splicing, making professional-grade towing equipment accessible to DIY installers. Whether you're setting up a fifth wheel, flat-towing a vehicle behind an RV, or connecting a utility trailer, Hopkins engineering ensures reliable electrical connections that stand up to road vibration, weather exposure, and years of use.</p><h3>Vehicle Cleaning and Care Products</h3><p>Beyond towing, Hopkins has established itself as a major player in the vehicle care market. In 2005, Hopkins purchased Carrand Companies, making it the number one vehicle cleaning company year-round. The company manufactures <a href="/1610-hopkins-liquid-car-wash-16659">liquid car wash</a> products under several respected brands, including Rain-X, AutoSpa, Detailer's Choice, and Tanner's Select.

From high-foaming car wash concentrates to waterless wash solutions and premium chamois, Hopkins offers vehicle enthusiasts and everyday drivers a complete range of cleaning tools and chemicals engineered for superior results.</p><h3>Innovation Through Strategic Growth</h3><p>Between 1997 and 2018, Hopkins broadened its automotive focus through strategic acquisitions including Towing Accessory Products, Brake Buddy RV tow-brakes, and Tiger Accessories Group with its Blazer brand of trailer lighting. This expansion strategy has allowed Hopkins to offer integrated towing systems rather than isolated components. The company maintains rigorous quality control standards and backs many products with industry-leading warranties, demonstrating confidence in their manufacturing processes and materials. With distribution facilities across North America and a dedicated technical support team, Hopkins ensures that professional installers and DIY customers alike have access to the expertise needed for successful installations.</p>

Easy shopping experience.

Overall good purchase. However it would have been nice to be notified the shipments were coming in 4 boxes instead of us having to reach out to figure out the partial shipments to assure we would receive the full order.

Good pricing
