Dexter Axle

<h3>About Dexter Axle</h3><p><strong>Dexter Axle</strong> has been a cornerstone of the trailer components industry since 1960, when Leonard Dexter founded the company in Elkhart, Indiana, to serve the then-booming manufactured housing and recreational vehicle markets. More than six decades later, Dexter has grown into one of North America's most recognized names in trailer running-gear, with over 3,800 employees, 20 manufacturing facilities, and a distribution network spanning more than 50 company-owned locations across the United States and Canada.</p><p>What began as a modest line of light-duty sprung axles has expanded into a sweeping catalog that covers virtually every component a trailer builder or operator could need — from actuation systems and door hardware to torsion axles and venting products. Dexter's growth philosophy has always centered on developing new, higher-quality products rather than standing still, and that relentless drive to innovate is reflected in the 26 patents the company has filed across vehicle braking, suspension, and related technologies.</p><p>Today Dexter serves the utility trailer, recreational vehicle, marine, agricultural, and specialty trailer markets, and its products are manufactured using state-of-the-art robotics, precision welding equipment, and automated machining processes — giving buyers confidence that every component meets exacting standards from concept through completion.</p><h3>Brakes &amp; Brake Systems</h3><p>Dexter's reputation was built in large part on its trailer braking solutions. The company's <a href="/7314-dexter-axle-brakes-brake-parts-200202">Brakes &amp; Brake Parts</a> lineup covers electric drum brakes, hydraulic disc brakes, and the well-known Nev-R-Adjust self-adjusting brake system — a design that reduces maintenance intervals and keeps stopping performance consistent mile after mile. For more specialized needs, Dexter also offers a focused selection of <a href="/7314-dexter-axle-other-brake-parts-50736">Other Brake Parts</a>, including actuators, brake controllers, and hardware kits that round out a complete braking installation.</p><h3>Axles, Springs &amp; Suspension</h3><p>At the heart of any trailer is its axle and suspension system. Dexter's <a href="/200122-axle-spring-parts-dexter-axle-7314">Axle &amp; Spring Parts</a> range encompasses both traditional sprung axles with leaf-spring mounts and the brand's proprietary Torflex rubber torsion suspension axles, which deliver an independent, maintenance-free ride. Builders and repair shops looking for a complete solution can turn to Dexter's <a href="/7314-dexter-axle-suspension-kit-10922">Suspension Kits</a>, which bundle the essential components needed for a proper suspension rebuild or upgrade in a single, convenient package.</p><h3>Hubs &amp; Bearing Components</h3><p>Reliable wheel-end performance depends on quality hubs, and Dexter's <a href="/7314-dexter-axle-hubs-200550">Hubs</a> lineup delivers exactly that. Covering a wide range of bolt patterns and bearing configurations for light-duty through heavy-duty trailers, Dexter hubs are engineered to pair seamlessly with the brand's axle spindles — including the E-Z Lube spindle design that simplifies routine bearing maintenance in the field.</p><h3>A Trusted Name Across Industries</h3><p>Whether you are outfitting a boat trailer, a horse trailer, a utility flatbed, or a full-sized RV, Dexter Axle offers the depth of product and the documented engineering support to get the job done right. With over 50 million axles installed over its history, the brand's track record speaks for itself.</p>

Wow, I ordered H&R springs for my Porsche and they arrived in 2 days and for 15 dollars cheaper then anyone else on the internet. Awesome place to shop and the live accurate inventory is how everyone should operate.

It was ok

Great

Ordering was easy and quick. Your form showed Paypal but wouldn't let me select it.

Great priced product

fast , e-z , great price

price is cheap. site is easy enough to use. I wish shipping is included.

Best prices and i found exactly what i needed and the appropriate information. The fifth star is for the fact that a regular search for the part of auto-parts did not reveal this website. Found via Google - which totally fine, but 2 sources of marketing

good so far

Easy shopping, but would be nice if the picture matched the model, it would have saved me 20 minutes of waiting on the phone for customer service.

Fast shipping even around the holidays and the cheapest price I could find on my Thule t2 bike rack I would buy here again

great and easy...

Good
