Part Number: WS10-3-KA
Heavy-duty adjustable aluminum ball mount designed for 3" truck receiver tubes. This keyed-alike system includes dual stainless steel hitch balls and integrated locking components for secure towing. Adjustable in 1" increments with up to 10" drop or 11" rise to properly level a wide range of trailers.
R&P Knowledge Hub
Proper trailer leveling is critical for safe towing. Adjustable ball mounts allow correction of tongue height differences between truck and trailer. Always match hitch ball size exactly to the trailer coupler and confirm receiver size compatibility before installation.
Maximum trailer weight (GTW) and tongue weight ratings must never exceed the lowest-rated component in the towing system (vehicle, receiver, ball mount, or hitch ball).
