Jacks & Couplers Technical Guide
What weight capacity jack do I need for my trailer?
The jack should have a capacity of at least 10-15% of the trailer's gross trailer weight (GTW). For example, a 7,000 lbs trailer requires a jack with at least 1,000 lbs capacity. Always choose higher capacity for a safety margin.
What is the difference between A-frame and swivel jacks?
A-frame jacks mount directly to the trailer A-frame and are more compact. Swivel jacks have a rotating base that allows the jack to fold up when not in use, providing greater ground clearance.
How do I measure coupler size?
Coupler size is measured by the hitch ball diameter. Common sizes are 1-7/8", 2", and 2-5/16". Check your coupler label or measure the inside diameter of the coupler cup. Size must match the hitch ball exactly.
What is the difference between latch and lock couplers?
Latch couplers use a simple lever mechanism to secure the ball. Lock couplers have an integrated locking mechanism requiring a key, providing additional security against theft. Both types should be secured with a safety pin.
How often should I lubricate my jack?
Lubricate the jack mechanism every 6 months or after exposure to wet or dusty conditions. Use marine grease or multi-purpose grease on gears and lift screw. Wipe excess grease to prevent dirt buildup.
What are the safety chain requirements?
Safety chains must have a break strength of at least the trailer's gross weight. Cross them under the coupler in an X pattern to cradle the tongue if the coupler fails. Leave enough slack for turns but not so much they drag on the ground.
