Why Hitch Maintenance Matters
A worn ball coupler can bounce off the hitch ball at a railroad crossing. A cracked king pin plate can separate the trailer from the truck on a highway curve. A weight distribution hitch that is improperly adjusted transfers too little weight to the front axle, causing the tow vehicle to feel light in the steering and lose braking effectiveness on the front wheels. These are not theoretical risks — they are the scenarios we see in the aftermath of towing accidents.
Services We Provide
1 Ball Coupler Inspection & Replacement
We inspect coupler latch engagement, ball socket wear, and handle mechanism function. Worn couplers that allow vertical play on the ball or do not latch securely are replaced with properly rated replacements. We verify the coupler rating matches or exceeds your trailer's gross vehicle weight rating.
2 Fifth-Wheel King Pin & Plate Service
We inspect the king pin for wear, cracks, and proper engagement with the fifth-wheel hitch. We check the king pin plate and mounting bolts for cracks and loose fasteners. On gooseneck conversions, we verify the adapter and ball are properly rated and secured.
3 Weight Distribution Hitch Setup & Adjustment
We install and adjust weight distribution hitches (Equal-i-zer, Husky, Blue Ox, Reese) for proper tongue weight transfer. Correct adjustment levels the tow vehicle and trailer, restores front-axle braking, and improves steering response. We measure before and after ride height to verify proper weight transfer.
4 Safety Chain & Breakaway Cable Inspection
Safety chains must be properly crossed under the coupler and rated for the trailer weight. We inspect chain links for wear and stretching, replace corroded or undersized chains, and verify breakaway cable length and attachment point. These components are your last line of defense in a separation event.
5 Receiver Hitch Inspection & Upgrade
We inspect receiver hitches for cracks, corrosion, loose mounting bolts, and proper class rating for your trailer weight. Hitch receivers that show structural cracks or have been overloaded are replaced. We also upgrade Class II receivers to Class III or IV when towing needs change.
Frequently Asked Questions
How do I know if my trailer coupler is worn out?
Signs of a worn coupler include visible play between the coupler and ball (the coupler rocks or bounces on the ball), a latch that does not fully engage or requires force to close, visible wear grooves inside the coupler socket, and rust or corrosion that has thinned the coupler walls. If you hear clunking from the hitch area while driving, the coupler or ball may be worn. We measure coupler socket diameter and compare to specifications.
How often should a weight distribution hitch be adjusted?
Check and adjust the weight distribution hitch at least once per year and any time you significantly change the trailer's loaded weight or weight distribution. The spring bars should be re-tensioned if the tow vehicle nose rises or drops compared to its level towing position. We recommend a professional setup any time you install a new hitch or change tow vehicles.
What size ball do I need for my travel trailer?
Common travel trailer ball sizes are 2 inches and 2-5/16 inches. The correct size is stamped on the coupler. Using the wrong ball size is extremely dangerous — a 2-inch ball in a 2-5/16-inch coupler will latch but can bounce out under load. We verify ball and coupler size match on every inspection.
Can you install a fifth-wheel hitch in my truck?
Yes. We install fifth-wheel hitches and gooseneck hitches in truck beds. Proper installation requires drilling into the truck bed and bolting to the frame — not just setting a hitch on the bed floor. We install the mounting rails, hitch head, and wiring, and verify king pin engagement with your specific trailer.
Do safety chains really need to be crossed under the coupler?
Yes. Crossing safety chains under the tongue creates a cradle that catches the tongue if the coupler separates from the ball, preventing the tongue from dropping to the pavement and pole-vaulting the trailer. Uncrossed chains allow the tongue to drop and dig into the road surface. Washington State law requires safety chains on all towed trailers.
