<h3>Pollak: Over a Century of Electro-Mechanical Engineering Excellence</h3><p><strong>Pollak</strong> has one of the most storied origins in the American auto parts industry. Founded in 1909 by Joseph Pollak as a small tool and die shop in Boston, Massachusetts, the company has spent more than 115 years evolving alongside the transportation industry — from crafting precision tools during World War I to engineering the electrical switches found in military aircraft during World War II. That heritage of precision manufacturing is woven into every product the brand produces today.</p><p>Now a part of the Standard Motor Products (SMP) family, Pollak engineers, manufactures, and distributes a wide range of electro-mechanical components — including connectors, switches, sensors, and related items — serving the heavy truck, off-road, RV, marine, industrial, and towing industries. Its facilities operate under TS16949 and ISO14001 certifications, and the brand has earned Q1 preferred status at Ford, General Motors&apos; Mark of Excellence, and Chrysler&apos;s Gold Pentastar, reflecting a deep commitment to quality that resonates across OEM and aftermarket channels alike.</p><h3>A World Leader in Towing Connectivity</h3><p>Pollak is perhaps best recognized among truck and trailer owners for its dominance in towing electrical components. The brand is widely regarded as a world leader in original equipment trailer wiring connectors, adapters, and extensions, with aftermarket offerings built to the same exacting standards as its OEM parts. Whether you&apos;re replacing a worn factory socket on a half-ton pickup or outfitting a heavy-duty rig for long-haul towing, Pollak&apos;s lineup covers the full spectrum of connection types.</p><p>For anyone managing a towing setup, <a href="/2632-trailer-wiring-adapter-connector-pollak-7495">Pollak Trailer Wiring Adapter Connectors</a> are a go-to solution. Available in configurations from 4-way flat to 7-way blade, these connectors are precision-engineered for light-duty and medium-duty trucks and SUVs, and several models come recommended directly by major vehicle manufacturers. The brand&apos;s heavy-duty plugs and accessories are designed to meet and exceed SAE J560 standards, feature floating pins for ease of alignment, and accept a wide range of wire gauges for maximum versatility.</p><p>Complementing the connector lineup, <a href="/7495-pollak-socket-assembly-10144">Pollak Socket Assemblies</a> are purpose-built for vehicle-side towing applications. Designed to withstand the harsh environment of an exposed external mount under a truck&apos;s rear bumper, Pollak sockets incorporate features like stainless steel spring lid hinges, runner gaskets to prevent moisture intrusion, and drain slots for all-weather durability — the kind of thoughtful engineering detail that has kept Pollak at the forefront of the towing industry for generations.</p><h3>Why Choose Pollak?</h3><ul><li><strong>115+ years of manufacturing expertise</strong> dating back to 1909</li><li>OEM-grade quality trusted by Ford, GM, Chrysler, Freightliner, John Deere, and more</li><li>ISO and TS16949-certified manufacturing facilities</li><li>Products engineered for heavy truck, RV, marine, towing, and agricultural applications</li><li>Aftermarket parts built to the same standards as original equipment components</li></ul><p>From the farm field to the open highway, Pollak&apos;s reputation for innovative design and dependable manufacturing makes it a trusted name for anyone who demands reliable electrical connectivity from their towing and vehicle systems.</p>

Thank you for having the items needed

Thanks Autoplicity you had the best prices I could find, fast shipping, and everything I ordered was exactly what I was looking for! Great Customer Service!

Thanks!

Fast shipping, good customer service!

So far so good, the site does freeze up from time to time, but not as often as it used to.

Easy and perfect

very quick and easy

Amazing Prices, saved hundreds over other Performance websites. Fast Shipping to top it off! Even with having to pay for shipping I saved $160 using Autoplicity over another "racing" website. Will absolutely do business with again!

This was my second order with Autoplicity. The first order I had to call to get an update, but just happens the part was out for delivery the day I had called. This second order went without a hitch! In both cases, shipping was fast and the products delivered at great prices, not to mention some of the best prices on shipping. I will definitely look here for my future parts needs!!
