8-inch Wheel Trailer Jack 13in Vertical Movement - 2,000 lb Capacity

In this review the 8-inch Wheel Trailer Jack is judged on build, rollability and corrosion resistance for mid-sized trailers and boats. The bottom line: it is a practical, heavy-duty jack for owners who need easy maneuvering and a higher load capacity than typical 1,000 lb units. The single biggest reason to buy is the large 8 x 4 in wheel combined with a 2,000 lb rating, which makes moving mid-sized boats and pontoon trailers over gravel or soft ground noticeably easier.

Key Features

• 2,000 lb Load Capacity: Provides the extra carrying margin needed for mid-sized boats and pontoon trailers so the trailer can be moved without strain.
• 13in Vertical Movement: Gives a 13in retracted height and 26in extended height, covering a wide range of hitch heights for easier coupling and storage.
• 8 x 4in Wheel: The wider wheel rolls more smoothly on gravel, dirt and soft surfaces, reducing hangups compared with narrow 6in jack wheels.
• Fits up to 3 x 5in Frame: Designed to clamp to common 3 x 5in trailer frames for straightforward installation on many mid-sized rigs.
• Dacromet Process Hardware: Crank, springs and bolts use a military-grade anti-corrosion treatment to slow rust compared with standard zinc plating.
• Corrosion-Resistant Finish: Heavy steel construction with black powder coating and zinc plating helps resist water, road salt and dirt for longer service life.

Who It's For

The jack is best for RV and boat owners with mid-sized trailers or pontoon trailers who need a durable, higher-capacity jack and smoother rolling on loose surfaces. It suits people who frequently move trailers short distances by hand and want a wider wheel and tougher hardware than entry-level jacks.

Those who should look elsewhere include owners of very small utility trailers where a 1,000 lb unit would suffice or users who need a swing-away or electric jack feature not offered here. If absolute marine-grade stainless components are required for constant saltwater exposure, consider specialized marine jacks with full stainless steel hardware.

Pros & Cons

Pros

• Large 8 x 4in wheel delivers noticeably better rollability on gravel and soft ground.
• 2,000 lb capacity and 13in vertical travel provide flexibility for mid-sized trailers and boats.
• Durable finish and Dacromet-treated hardware help resist corrosion beyond typical zinc plate.
• Easy to install on up to 3 x 5in frames and straightforward to operate by hand crank.

Cons

• Some users report surface rust over time, so additional maintenance may be needed in harsh wet climates.
• Not powered; manual crank operation may be slow for very heavy loads or frequent use.
