KYX Boat Trailer Jack 1500 lb Swivel Bolt-On with 8" Poly Wheel, Corrosion-Resistant 10.6" Lift

KYX 1500 lb Boat Trailer Jack is a swivel bolt-on trailer jack with an 8" polypropylene wheel and marine-grade corrosion resistance for reliable lifting and maneuvering of boat, RV, and utility trailers.

Whether you’re preparing a boat for launch, hitching an RV, or moving a utility trailer on gravel or sand, the KYX trailer jack combines a 1500 lb lifting capacity with a swivel, fold-away design and a large 8" PP tire to make setup and towing easier. Built from heavy-duty steel with an anti-rust coating, it’s engineered for frequent outdoor and coastal use where resistance to corrosion and reliable movement over soft ground matter most. The bolt-on kit includes the hardware needed for fast installation, and the jack’s 10.6" vertical lift gives enough range for most trailer tongues.

How much weight can this jack safely support?

The KYX jack is rated for a maximum static load of 1500 pounds, suitable for many small to mid-size boat trailers, utility trailers, and lighter RV tongues. It offers a dependable lift range of about 10.6" vertical travel, allowing you to raise and lower the trailer tongue with control.

• 1500 lb load capacity for tongue and front-end support
• 10.6" vertical lifting travel for most trailer setups
• Designed for static support during hitching and level adjustments

Why is the 8" polypropylene wheel important for trailer handling?

The oversized 8" PP (polypropylene) tire spreads the load over a larger surface area to reduce sinking in mud, sand, and loose gravel. Its robust construction helps ensure smooth rolling during manual positioning and when moving trailers short distances by hand.

• Large diameter improves stability on soft ground
• Durable PP material resists wear and outdoor exposure
• Nice rolling action for easier manual maneuvering

Is this jack suitable for marine and coastal use?

Yes — the KYX jack is built with a heavy-duty steel body and an anti-rust coating formulated for marine environments. While no finish is impervious to extreme saltwater immersion, this jack’s corrosion-resistant treatment and wear-resistant components are intended to extend service life near coasts and boat ramps.

• Anti-rust coated steel construction for outdoor durability
• Waterproof and wear-resistant components to withstand wet conditions
• Recommended maintenance: rinse off salt and apply protective lubricant periodically

How does the swivel bolt-on design help with installation and towing?

The swing-up swivel feature lets the jack fold parallel to the trailer frame for added ground clearance while towing. It supports both bolt-on and welded installation methods and comes with the necessary hardware to get it mounted quickly, making it a practical retrofit or replacement jack.

• Swivels up to lie flat alongside the tongue during travel
• Includes bolt-on hardware for straightforward installation
• Works with bolt-on and welded mount points for flexibility

Who is this for: The KYX 1500 lb Boat Trailer Jack is aimed at recreational boat owners, weekend RVers, horse trailer users, and anyone who needs a rugged, easy-to-install jack for light- to mid-weight trailers. If your trailer tongue load stays within the 1500 lb rating and you value corrosion resistance, a large wheel for soft surfaces, and a compact swivel design for towing clearance, this jack is a practical, value-minded upgrade to make launching, hitching, and short-distance maneuvering simpler and more secure.
