HWH

<h3>About HWH Corporation</h3><p>HWH Corporation has been engineering hydraulic solutions since 1967, when the company first began designing machines and hydraulic systems for heavy-equipment giants like John Deere and Caterpillar. That agricultural background gave HWH a deep foundation in precision hydraulics — and it wasn't long before the RV industry took notice. Recognizing an unmet need for purpose-built leveling technology in recreational vehicles, HWH pivoted to develop dedicated systems for motorhomes, horse trailers, and specialty vehicles, ultimately becoming one of the most recognized names in the RV hydraulics space.</p><p>Headquartered in Moscow, Iowa, <strong>HWH Corporation</strong> designs, manufactures, and assembles the majority of its components in-house. This vertically integrated approach allows the company to maintain strict quality control and consistent product performance across its entire lineup. From the electroless nickel-plated jack rods engineered for corrosion resistance to weather-tight electrical connections and custom-engineered seals, every detail reflects a manufacturer that takes durability seriously.</p><h3>HWH's Core Product Lines</h3><p>HWH's product catalog centers on hydraulic and air leveling technology for motorized and towable vehicles. The company manufactures a broad range of jack styles — including Kick-Down Jacks, Straight-Acting Jacks, Spring-Retracted Jacks, and Power-Up/Power-Down Jacks — in lifting capacities engineered to fit everything from compact Class B vans to heavy Class A diesel pushers. Their proprietary BI-AXIS&reg; automatic leveling system is a standout product, using onboard computer logic to select the most efficient jack combination for fast, stable leveling with minimal stress on the coach structure.</p><p>Beyond leveling, HWH produces hydraulic and air-powered slide-out systems, automatic step systems, room extension systems (including above-floor, below-floor, and full-wall designs), saddle-rack systems, and energy management components. For horse trailer and specialty trailer owners, HWH's Power-Extend/Power-Retract Jacks serve as precision landing gear or complete leveling solutions.</p><h3>Why RV Owners Trust HWH</h3><p>One of HWH's most cited advantages is its spring-loaded retraction design. Unlike competitors whose jacks must be powered both up and down, HWH's spring-retracted jacks automatically return to the travel position if hydraulic power is lost — meaning a jack failure on the road won't leave a coach stranded with legs deployed. HWH jacks are also engineered to provide higher ground clearance during travel, with extension ranges capable of handling extreme slopes in emergency situations.</p><p>HWH supports its customers with a robust network of authorized dealers, an online Technical School, product identification tools, and direct factory support. The company partners with major OEM coach builders including Newmar, REV Group, and Tiffin, underscoring the confidence that professional manufacturers place in HWH systems. For owners sourcing replacement chain hardware, shackles, or anchoring components within their HWH parts catalog, a wide selection of hardware is available to keep systems operating at factory specification.</p>
