The Multiquip EE56638 Bulldog Hitch 2-5/16 in Ball Adjustable is a genuine OEM towing component designed for Water Trailer and LS600P series equipment. This is a direct-fit optional replacement hitch sourced from Multiquip and engineered to match the original coupling specification used on these units. Compatibility spans the WT5C, WTE5C, WT5CSG, WT5HP, WTE5HP, WT5HPSG water trailer variants as well as the LS600P concrete pump, making it a versatile hitch solution across multiple Multiquip equipment families. Count on this OEM part to deliver the correct fit and tow rating the machine was designed around.
Key Features
- OEM-Matched Coupling Spec — Genuine Multiquip part manufactured to the same 2-5/16 in ball specification as the original hitch, ensuring consistent tow ball engagement and load transfer.
- Adjustable Height Design — The adjustable coupler allows the drawbar to be set at the correct height for your tow vehicle, keeping the trailer level under load.
- Bulldog-Style Locking Mechanism — Heavy-duty Bulldog coupler construction provides positive ball retention and resists accidental unhitching during transport over rough terrain.
- Broad Fitment Coverage — Fits WT5C, WTE5C, WT5CSG, WT5HP, WTE5HP, and WT5HPSG water trailers, plus the LS600P concrete pump trailer — one part number covers multiple configurations.
- Towing Safety Integrity — A worn or damaged hitch coupler can compromise trailer control and braking response; replacing with this genuine OEM part restores the safe towing capacity the equipment was rated for.
A hitch coupler connects the trailer tongue to the tow vehicle's ball mount, transferring all towing and braking forces between the two. On water trailers and pump trailers like those in the Multiquip lineup, the coupler must handle not only the static weight of the loaded tank or pump unit but also the dynamic surge loads that occur during braking. The adjustable feature allows the coupler to be positioned so the trailer tongue sits level, which is critical for proper weight distribution and stable handling. When a coupler wears, cracks, or fails to latch securely, it creates a serious tow-safety risk and should be replaced before the equipment is moved.
