Pacific Rim Int'L Couplers/Pins & Accessories
Pacific Rim Int'L Couplers, Pins & Accessories: RAM-Series Trailer Connection Hardware
When it comes to connecting a trailer safely and securely to a tow vehicle, the coupler is the single most critical piece of hardware in the chain. Pacific Rim International, LLC — the manufacturer and distributor behind the well-regarded RAM and RAM-Premium Series brands — has been engineering trailer couplers, pins, and related accessories since 2004, building on a precision-manufacturing heritage that dates back to 1992. Their Couplers, Pins & Accessories lineup reflects that depth of experience, offering solutions that span recreational boat trailers all the way up to heavy-duty commercial haulers.
A Coupler for Every Trailer Type
Pacific Rim International's coupler range is notably broad. A-frame couplers — such as the CA-5100-B rated to 5,000 lbs — are ideal for lighter-duty and recreational towing applications like boat and utility trailers. For medium-duty needs, their stamped adjustable-tongue couplers (like the CTA400 series) accommodate a 2-5/16" ball and are rated up to 14,000 lbs, providing flexibility across a wide range of trailer tongue configurations.
At the heavy end of the spectrum, the RAM gooseneck coupler lineup covers round-tube and square-tube designs rated from 24,000 lbs up to 40,000 lbs, with kingpin variants available for fifth-wheel-style gooseneck connections. These high-capacity couplers are engineered with features such as an exclusive one-piece cast head design with a curved internal ball clamp bar for superior strength, a hidden spring latch mechanism for ease of use and protection of moving parts, and welded belly bands on the outer tube for added rigidity under load. High-capacity models accept a 2-5/16" ball (25K and 30K) or a 3" ball (40K), and load-bearing pin designs are built to meet SAE J2638 standards where applicable.
Pins, Retaining Hardware, and Accessories
A complete towing connection depends on more than just the coupler head itself. Pacific Rim International's pins and accessories fill in the details — from retaining pins and set screws to the small-but-critical hardware that keeps a coupler locked, aligned, and road-ready. Proper pin inspection and replacement is essential for safe operation, and having OEM-matched replacement hardware on hand means trailer owners don't have to sideline a rig over a worn or damaged component.
Vertically Integrated Quality at a Value Price
What distinguishes Pacific Rim International in this category is their vertically integrated manufacturing model. Products are designed and built at their own family-owned facilities in Ningbo, China, then distributed through fully insured U.S. companies with stock held at four domestic warehouse locations. This direct-from-manufacturer approach allows them to deliver high-quality, precision-built couplers and hardware at a value price point — a combination that has earned the RAM line a strong following among trailer builders, RV manufacturers, and individual trailer owners alike.
Whether you're replacing a worn A-frame coupler on a boat trailer, sourcing pins for a gooseneck rebuild, or specifying hardware for a new heavy-haul build, Pacific Rim International's Couplers, Pins & Accessories line offers a well-tested, capacity-rated solution.
