Velvac 100101 Fifth Wheel Air Cylinder
The Velvac 100101 is a common choice for fifth wheel hitch systems requiring a robust air cylinder. It features a 2-1/2 inch bore and a 6-3/4 inch stroke to provide steady actuation. This cylinder is designed to fit standard fifth wheel configurations and deliver reliable air pressure for hitch alignment and locking mechanisms. When selecting this component, ensure compatibility with your trailer’s mounting brackets and your vehicle’s air supply system. Maintenance involves checking seals and ensuring clean, dry air supply to prevent corrosion or binding in the cylinder bore.
Air Cylinder For Holland 5th Wheels Replaces XA-2524-R
This replacement air cylinder from Parts Express is designed for Holland fifth wheel systems and substitutes multiple part numbers including 2524P and 401267. Featuring a gold anodized tube for corrosion resistance and a 100 PSI operating pressure, it provides durable performance under varying towing conditions. When installing, verify the exact Holland model and ensure the cylinder’s bore, stroke, and port fittings align with your current assembly. This option suits owners seeking a straightforward replacement with proven compatibility across Holland 5th wheel configurations.
Holland Fifth Wheel Air Cylinder KP2524R131
The Automann offering KP2524R131 serves as a compatible Holland air cylinder replacement with a 2-1/2 inch bore and 100 PSI operating pressure. It lists compatibility with Holland XA2524R131 and Velvac 100102 models, making it a flexible choice for mixed-fleet trailers or replacement parts. The 1/4 inch FTP port is a common connection standard across several fifth wheel systems. As with other cylinders, inspect seals and mounting hardware for wear, and confirm port sizing and thread types before ordering to minimize installation effort.
BestFit 54 Inch Coiled Air Line For 5th Wheel Trucks
Although not a cylinder itself, the BestFit 54 inch coiled air line is a practical accessory for fifth wheel air systems. A 1/4 inch line with a generous coil length offers flexibility for routing from the truck to the trailer, reducing tension and wear on connections during sharp turns or suspension movement. This USA-made line supports reliable air delivery and helps maintain consistent cylinder performance by ensuring clean, unobstructed air flow. When selecting air lines, consider length requirements, heat resistance, and compatibility with your fittings and quick-connects.
Lippert CURT L05 Air Ride 18K Fifth Wheel Pin Box
The Lippert CURT L05 air ride pin box integrates an internal airbag to dampen hitch motion, reducing chucking and vertical tug on the tow vehicle. Rated for up to 18,000 pounds, this system adds a buffer to absorb road shock and vibrations that can transfer to the RV. It features a black powder-coated finish for corrosion resistance and a compact form factor suitable for many fifth wheel-to-truck configurations. Consider the added benefit of enhanced ride quality versus installation complexity and the weight capacity required for your trailer and cargo load.
Buying Guide
Key purchase considerations when evaluating fifth wheel air cylinders and related components include compatibility, operating pressure, bore and stroke, and port type. A larger bore generally provides more force for hitch actuation but may require more mounting clearance. Check whether the cylinder is a direct replacement for your current model or if adapters are needed. Consider corrosion resistance, especially for outdoor mounting, and the availability of seals and replacement parts. For air lines, assess length, flexibility, weather resistance, and compatibility with your trailer’s fittings. If shopping for an air ride pin box, evaluate load rating, ease of installation, and the overall impact on towing stability. Finally, compare manufacturer support and warranty terms to ensure long-term reliability in varying climates and road conditions.
If you are upgrading a full fifth wheel system, a combination approach often yields the best results: a high-quality air cylinder paired with a robust air line and, where appropriate, an air-ride pin box to minimize hitch motion. Ensure all parts meet your vehicle’s weight rating and the trailer’s mounting geometry. Finally, verify that the chosen components are compatible with your vehicle’s air supply system to maintain consistent performance across trips and seasons.
