About JOST

JOST International, or simply JOST, is an international supplier and world market leader for the commercial trucking industry. It is widely recognized for its fifth wheel couplings and landing gear with internal gears. A core brand of JOST-World, a leading global producer and supplier of safety-critical components and systems for commercial vehicles, Jost International is committed to developing sensor-controlled solutions to make fleet operations easier, safer, and more efficient.

JOST International’s humble beginnings can be traced back to 1952 when JOST-World first started as a factory for ball-bearing turntables in Neu-Isenburg, Germany. Over the years, JOST has expanded its operations in different parts of the world, including South Africa, Italy, Great Britain, France, and Belgium. This has paved the way for the company to be a global market leader in the production of modules, systems, and components for commercial vehicles.

During the early 1980s, JOST International Corp. was incorporated after submitting the patent application for the very first steel cast fifth wheel coupling in Grand Haven, Michigan. Since then, it has grown to become a world market leader in the production of fifth wheels and landing gears and a renowned supplier of turntables and kingpins for the commercial trucking industry.

Today, JOST International’s dedicated and hardworking team remains steadfast in its goal to design and develop the most efficient and safest truck and trailer products. Although the company has achieved great success over the years, the people behind it continually work to innovate and improve its product lines to cater to the changing needs of commercial trucking fleets.

Jost Parts

JOST International offers a comprehensive range of truck and trailer solutions at competitive prices. Its product lines include fifth wheels, landing gears, turntables, and kingpins. All these JOST parts are designed and developed in the company’s ISO-certified facilities in Michigan and Tennessee.

Fifth Wheels

JOST is a pioneer for fifth wheel coupling devices explicitly designed for truck and trailer applications. These products are standard options at OEM and aftermarket since they feature a unique yet safe and simple locking mechanism with only four moving parts.

• JSK37U Series - Made with a cast ductile iron topplate, the JSK37U series consists of anti-high coupling lugs, steel wear or cushion ring, a double lock, and infinite adjustment. It requires only 60 lbs of pull force to open, and it features the original locking mechanism that all other JOST wheels are based on.
• JSK36N Series - Designed as a stamped steel fifth wheel, the JSK36N series is a lightweight and economical OEM entry-level wheel that makes a perfect choice for those with a short trade cycle.
• JSK37Y Series - Engineered for terminal tractor applications, the JSK37Y series offers a longer service life as it’s made with replaceable wear areas.
• JSK37H & JSK37F Series - These two fifth wheel series are offered to replace older competitive designs. They share the same features as the JSK37U series.

Landing Gears

JOST International is a trusted name in the design and development of trailer landing gear and landing gear parts. It has been supplying these products to OEM, Fleet, and Aftermarket partners worldwide for over 20 years. What makes JOST landing gear unique is that it features the brand’s signature internal gearbox. This specific gearbox significantly reduces moisture intrusion and protects gearing from damage.

The JOST landing gear line is consists of six major products: the Standard A400, Magnum 5 Year A440, Magnum 10 Year A450, Heavy Duty 10 Year H450, Ultralight UL500, and Alumilight AX100. These JOST parts vary in static load capacity, lifting capacity, side load capacity, and grease pkg. Rating, but they all meet TTMA and AAR specifications. Other features and benefits include:

• All JOST landing gears do not have an external gearbox
• Highly reliable austempered ductile iron gears
• Offer spline shifting and double “D” crank
• Gears are well-protected and have no shaft misalignment
• Do not easily wear out
• Provide easy shifting
• Designed to transfer crank torque directly into the shaft

Turntables

JOST takes pride in its wide selection of ball bearing turntables designed to cover the complete spectrum of trailer technology. These sturdy and reliable products are manufactured following strict quality control standards for maximum performance and efficiency.

• Single Row Ball Bearing Turntables - Designed for use on trailers and agricultural vehicles, the JOST single row ball bearing turntable connects the A-frame to the trailer chassis. It does this by allowing the axle to turn relative to the trailer frame, transferring both the radial and axial forces. This specific type of turntable is composed of the lower (outer) ring that's bolted to the A-frame and the upper (inner) ring that's connected to the trailer chassis.
• Double Row Ball Bearing Turntables - These turntables are used when the vehicle requires both strength and precision in material and design. They also guarantee the optimal distribution of radial and axial forces.

Kingpins

Designed for the most challenging roads, JOST kingpins are steel forged for maximum strength and deliver the optimal balance between impact and wear resistance. They may be used as OEM or aftermarket replacements and are designed to meet or exceed international standards for OEMs and fleet use. Here are the five options available for this product line:

• AAR Cruciform Style Kingpin - Properly installed JOST cruciform style kingpins will meet or exceed American Associate of Railroads (AAR) standard M-931, Society of Automotive Engineers (SAE), and Truck and Trailer Manufacturers Association (TTMA) performance requirements.
• SAE Mushroom Style Kingpin - This kingpin will meet SAE and TTMA performance standards when properly installed.
• SAE Spool Style Kingpin - Just like the mushroom style kingpin, the JOST spool style kingpin will also meet or exceed SAE and TTMA performance requirements if they are properly installed.
• AAR Square Spool Style Kingpin - Properly installed JOST square spool-style kingpins will also meet or exceed SAE and TTMA standards.
• Bolt-In Style Kingpin - When properly installed, this kingpin will meet SAE, TTMA, and Federal Motor Carrier Safety Regulations (FMCSR) performance standards.
