The Multiquip EE5663 Bulldog Hitch 2-5/16" Ball Adjustable is a genuine OEM optional hitch assembly designed for Multiquip Water Trailer series units — including WT5C, WTE5C, WT5CSG, WT5HP, WTE5HP, and WT5HPSG — as well as the LS600P concrete pump. This hitch provides a heavy-duty, adjustable connection point between your equipment and tow vehicle, ensuring a secure and properly aligned coupling every time. As a genuine Multiquip OEM part, EE5663 is built to the same specifications as the original hardware on your machine. If your existing hitch is worn, damaged, or you are upgrading to a 2-5/16" ball configuration, this is the correct replacement assembly.
Key Features
- Genuine OEM Construction: — Manufactured to Multiquip's original specifications, ensuring the correct load rating, adjustability range, and dimensional fit for towing applications on this equipment.
- Bulldog Brand Assembly: — Features a Bulldog-branded hitch head, a trusted name in trailer coupling hardware known for solid steel construction and repeatable latching performance.
- Adjustable Height Design: — The adjustable shank allows the hitch head to be set at the correct height for your tow vehicle, maintaining a level trailer stance under load.
- 2-5/16" Ball Coupling: — Sized for 2-5/16" tow balls, the most common heavy-duty trailer coupling standard, compatible with a wide range of trucks and tow vehicles used on commercial job sites.
- Broad Fitment Coverage: — Verified for Water Trailer models WT5C, WTE5C, WT5CSG, WT5HP, WTE5HP, WT5HPSG, and the LS600P concrete pump series.
- Towing Safety Compliance: — A correctly rated and properly functioning hitch coupling is critical for safe trailer towing; using the specified OEM assembly helps ensure the connection meets the load demands of fully loaded water trailer and pump equipment.
The hitch assembly is the primary mechanical link between a towed piece of equipment and the tow vehicle. On water trailers and towable concrete pumps, a properly functioning hitch must handle the combined weight of the equipment and its payload through acceleration, braking, and cornering. The Bulldog-style coupler used in the EE5663 latches over the tow ball and locks it in place, preventing separation during transit. When a hitch becomes worn, corroded, or mechanically compromised, it can fail to lock securely — creating a serious towing hazard and potential for equipment loss on the road.
