The Jack Boss 4 Ton Floor Jack is a strong and versatile tool that can lift up to 8,800 pounds, making it suitable for most cars, light trucks, and SUVs. Its low profile design with a lifting range from 3.9 to 20 inches allows it to easily slide under low-clearance vehicles and reach a comfortable height for maintenance tasks. One standout feature is the dual piston pump, which speeds up lifting — you can raise your vehicle up to five times faster than with a single pump jack, saving time and effort.
The wide base offers good stability when lifting heavy loads, which adds to safety during use. Made from solid materials, it feels durable and reliable for both garage work and roadside emergencies. However, at nearly 100 pounds, it’s quite heavy and less convenient if you need a highly portable jack for frequent carrying. Some users may find its size bulky for tight storage spaces.
If you want a dependable floor jack that handles a wide range of vehicles with quick lifting action and solid build quality, this Jack Boss model is a very capable choice, especially if portability is not your top priority.
The Jack Boss 3 Ton Low Profile Floor Jack is designed to meet the needs of car enthusiasts and everyday users alike, particularly those who work on vehicles with low ground clearance. With a capacity to lift up to 3 tons (6600 lbs), it can handle a variety of vehicles, from sedans to SUVs. One of its major strengths is the low profile design, which allows it to accommodate vehicles with lower clearance, making it ideal for sports cars or lowered vehicles.
The dual piston quick lift feature is another highlight, allowing for faster height adjustments. The jack's construction combines aluminum and welded steel, ensuring durability while still being relatively lightweight at 58.5 pounds. The large rubber saddle provides stability and protects the vehicle from damage during lifting.
There are a few drawbacks to consider, such as the lifting range, from 3-15/16" to 18-5/16", which may not be sufficient for taller vehicles or those requiring more elevation. Additionally, while portable, the weight can be cumbersome for some users, especially those looking for a jack they can easily transport. Safety is a key focus, with the jack meeting ANSI/ASME safety standards, which provides peace of mind during use. The included one-year warranty and support from the manufacturer is a plus for buyers who may have concerns or questions after their purchase.
The Sunex 6614 Air Hydraulic Floor Jack offers a high lifting capacity of 10 tons, making it suitable for heavy-duty applications. It can be operated manually or with air power, giving flexibility depending on the user's preference. The jack's hydraulic power unit is robustly designed to prevent leaks, and it includes wiper seals to protect the hydraulic system from contaminants, which is a significant plus for longevity and reliability.
The 3-position handle lock adds convenience, allowing the handle to be fixed in different positions for ease of use. Additionally, the jack's construction includes heavy gauge steel side plates for strength and stability, and the ram and pump piston are flash-chromed to prevent rust, enhancing durability. Maneuverability is made easier with roller-bearing front wheels and ball-bearing mounted rear caster wheels, along with a rear kick plate for navigating tight spots. Safety is addressed with bypass and overload valves to ensure the jack is not used beyond its rated capacity, and it complies with the ASME PASE-2014 safety standard, ensuring a high level of safety certification.
The jack's size and weight (66 x 20 x 13 inches and 0.48 ounces) might make it less portable compared to more compact models, so it's better suited for stationary use in a workshop or garage rather than for mobile applications. If you need a sturdy, high-capacity floor jack for heavy lifting tasks and have the space to accommodate its size, the Sunex 6614 could be a good fit.
