The jack is the cheapest part on a trailer and the one most likely to strand you. Here is how the main types differ.
A-Frame Jacks
A-frame jacks bolt to the coupler tongue of a standard bumper pull trailer.
Choose a rating well above your tongue weight. A 5,000 lb jack on a 14,000 lb trailer is a sensible pairing.
Swivel Jacks
Swivel jacks pivot up for travel so they clear curbs and ramps.
They suit utility trailers and lighter dump trailers that see frequent road time.
Direct Weld Square Jacks
These weld straight to the frame for maximum strength.
Heavy equipment trailers and goosenecks use them because there is no bolt plate to flex.
Marine Jacks
Marine jacks use sealed, corrosion-resistant construction for boat and saltwater use.
Rinse them after every launch and grease the screw twice a season.
