Types of CURT trailer tongue jacks

CURT Boat Trailer Jack

CURT A-Frame Trailer Jack

CURT Swivel Trailer Tongue Jack

CURT Heavy Duty Trailer Jack

Boat trailer jack

CURT boat trailer jacks are built to thrive under water exposure, equipping your boat trailer with a dependable support for miles to come. These trailer jacks also feature a jack wheel to give the boat trailer enhanced mobility when coupling to your vehicle or launching your boat at the boat landing.

A-frame trailer jack

A-frame trailer jacks are uniquely designed for an A-frame trailer. They feature a triangular bracket to be bolted onto the trailer tongue or welded into place. While A-frame trailer jacks do not swivel up and out of the way for travel, each is equipped with excellent vertical adjustment for easy coupling and safe towing.

Swivel trailer jack

The CURT swivel trailer jack features an integrated swivel bracket that allows the entire jack leg to tilt up and out of the way after hitching your trailer to your vehicle. CURT offers bracket-mount swivel trailer jacks and tube-mount or pipe-mount swivel trailer jacks to accommodate a variety of trailers.

Heavy-duty trailer jack

For large trailers, heavy loads and commercial jobs, a CURT heavy-duty trailer jack supplies superior lift and support capacity. We offer heavy-duty trailer jacks with support weight ratings up to 12,000 pounds. Each CURT heavy-duty trailer jack is also covered in a durable powder coat finish for maximum corrosion resistance on tough jobs.

Bolt-on or weld-on install

Most CURT trailer tongue jacks offer the option for either a bolt-on trailer jack installation option or weld-on trailer jack option, allowing you to best accommodate your unique trailer and towing setup.

Benefits of CURT boat trailer jacks

CURT Boat Trailer Jack Wheel

CURT Boat Trailer Jack, Water Trailer Jack

CURT Boat Trailer Jack, Swivel Trailer Jack

Enhanced mobility

Each CURT marine boat trailer jack is equipped with a trailer jack wheel at the base, giving your trailer enhanced maneuverability without requiring you to fully lift up the trailer tongue. This makes parking easier, coupling easier and launching and positioning your boat easier.

Water-resistant

These trailer boat jacks are constructed from high-strength steel for dependable strength and are shielded in a durable zinc plating. This tough finish is optimal for water exposure, frequent at the boat landing, ensuring long-lasting corrosion resistance of the trailer jack support leg and internal components.

Safe towing

For increased safety while towing and ease of use, all CURT boat trailer jacks mount with a swivel bracket. This allows the boat jack to swivel up and out of the way for travel, providing plenty of ground clearance for your trailer tongue. The swivel design also makes setup quicker and easier with less raising of the trailer jack leg required.

CURT jacks are made with quality to promote the life and function of your trailer, and they come in several different styles to accommodate your needs, whether you are a frequenter of the boat landing, the campground, the racetrack or the farm. CURT square jacks are a heavy-duty trailer jack option. They are designed to weld directly onto the frame of your trailer for superior holding strength.
