Built from heavy-duty steel with a 2.8-inch inner diameter and a 3.4-inch outer diameter, the cuff is engineered for durability and corrosion resistance.

The FlexHitch 5th Wheel to Gooseneck Adapter is crafted for semi-tractors with a 4-inch round tube. It enables a seamless switch between fifth-wheel and gooseneck towing, offering a cost-effective solution for fleets that require towing flexibility. The unit is built to withstand heavy-duty use, capable of handling up to substantial pulling forces with a sturdy steel construction. Its 30-pound weight contributes to easy handling on the job site, while reinforcing the reliability of daily towing operations.
Hezaosth Mack Kingpin Socket
The Hezaosth Mack Kingpin Socket targets Mack-operated axles with a 2 3/8″ outer diameter. The kit provides a dedicated screw socket and cap removal toolkit designed for high-torque use, compatible with common Mack front axles in the 16,000–20,000 lb range. This tool set emphasizes precise sizing, anti-slip geometry, and direct replacement compatibility with market-standard 11-3000 and ONI303T toolkits. Ideal for professional repair shops seeking a reliable, purpose-built solution for Mack kingpins.
OTC 4241 30-Ton Kingpin and Brake Anchor Pin Pusher
OTC’s 4241 Kingpin and Brake Anchor Pin Pusher uses hydraulic-like leverage to replace torch-and-hammer methods for kingpin removal on numerous truck and bus models. It accommodates kingpins from 7/8 inch to 2 inches in diameter and up to 11-1/4 inches long, with five collars and two pins for straight or tapered pins. The unit stands about 27-1/2 inches tall and 8-1/2 inches wide, offering a compact, robust option for shop floors and field service teams requiring controlled, reliable pin removal without power tools.
Buying Guide: Kingpin Equipment for Semi Trucks
- Application scope: Consider whether you need removal, installation, locking, or conversion capabilities. A kingpin press like the Tiger Tool 90150 focuses on removal efficiency, while adapters from FlexHitch enable towing flexibility, and locks from BISupply add security.
- Compatibility: Verify that tools match your vehicle classes (Class 3–8) and axle configurations. Tools like the Hezaosth socket emphasize compatibility with Mack axles, while the OTC 4241 covers a wide diameter range.
- Torque and leverage: For heavy-duty kingpins, high leverage and sturdy build quality reduce effort and risk. Assess whether a manual press, socket kit, or hydraulic-like pusher best fits your workshop.
- Durability and corrosion resistance: Semi trailer environments expose equipment to the elements. Look for solid steel construction, rust resistance, and protective finishes.
- Portability vs. bench use: Some tools are heavier but compact for field use, while others are bench-mounted. Determine your typical work setting before purchasing.
- Safety and security: Anti-theft locks add trailer security when parked. Consider fluorescent indicators or visible cues to enhance on-site safety and deterrence.
- Upgrade potential: Optional adapters expand tool usefulness across a broader fleet. If your fleet uses varied brands, adapters and compatible sockets can reduce total tool counts.
- Maintenance: Check for replaceable parts and availability of spare collars, pins, and adapters to minimize downtime when components wear out.
Overall, a well-chosen Kingpin toolkit or accessory set can streamline maintenance, protect valuable trailers, and support safer, more efficient operations across a fleet’s service and operations workflow. The selections above cover removal, locking, and towing conversions, providing options for both shop environments and on-road service.
