Introducing the GoJak® G9516: Redefining Heavy-Duty Vehicle Mobility
self-loading vehicle positioning systems since 1984, introduces the G9516 as the newest addition to the GoJak® Heavy Duty (HD) Series. Engineered for the increased curb weights and structural demands of modern platforms, the G9516 delivers a true 9,500-lb vehicle load capacity, enabling confident handling of full-size trucks, large SUVs, heavy electric vans, and Class B RVs. This includes high-weight platforms such as Ford E-Transit camper conversions, Sprinter-based RVs, Rivian commercial vans, and Mercedes eSprinter fleets. Purpose-built to manage these higher-load chassis with precision and stability, the G9516 establishes a new benchmark in controlled vehicle mobility, service efficiency, and shop safety.
Unmatched Load Capacity for Modern Vehicles
The GoJak® G9516 supports vehicle curb weights up to 9,500 pounds, or 2,375 pounds per wheel.
Upgraded Axle for Enhanced Durability
Features a wider, reinforced axle engineered to reduce deflection under heavy loads. The increased stiffness helps the jack stay level and disperse weight more evenly across all four casters, delivering smoother lifting and easier rolling.
Innovative Cam Mechanism for Effortless Operation
The patented cam mechanism provides selectable lift cycles for optimized mechanical advantage—offering a standard 3/4″ stroke for rapid lifting or a 3/8″ ratchet cycle in low gear for increased leverage under heavy loads. This dual-mode design improves force efficiency, reduces operator strain, and ensures consistent performance in demanding service environments.
Enhanced Ratchet Geometry
The updated ratchet doubles the tooth count with tighter 3/8″ spacing, creating a shorter, more controlled pedal stroke. Paired with the patented cam mechanism, it delivers higher mechanical advantage and reduced operator effort, especially when initiating heavy lifts.
Advanced Casters for Maximum Mobility and Protection
Built with a corrosion-resistant zinc finish, a top-plate swivel with a double ball-bearing raceway for effortless movement, and high load glass-filled nylon wheels with roller bearings for smooth, dependable motion
Versatility to Accommodate Diverse Tire Configurations
Upgraded thicker gauge galvanized steel rollers are engineered to resist bending under heavy loads, making them ideal for trucks, SUVs, and heavy EV vans. Supports tire widths up to 16 inches, including dual-rear wheel setups.
Proudly American-Made Craftsmanship
Since its inception, Zendex Tool Corp. has been committed to manufacturing high-quality tools in the USA. The G9516 embodies the superior craftsmanship and durability expected from Zendex products.
A Practical Solution for the Electric Vehicle Era
As electric vehicles (EVs) become increasingly prevalent, service providers face new challenges due to their weight and unique configurations. The GoJak® G9516 offers a practical solution, enabling effortless lifting and maneuvering of heavy EVs.
Conclusion
The GoJak® G9516 is more than just a wheel dolly; it’s a comprehensive solution designed to meet the evolving needs of the automotive industry. Proudly made in the USA by Zendex Tool Corp., it stands as a testament to quality, innovation, and expert engineering.
