BOSS CPA04340-03 – RTII Coupler Assembly (1995+)

The BOSS CPA04340-03 Coupler Assembly (RTII, 1995 and newer) is an OEM spec coupler designed to deliver secure, long-lasting connection between your plow frame and mount — essential for reliable performance and safe operation. As part of BOSS’s official parts lineup, this coupler assembly ensures a precise fit with RTII-style plow systems, helping you maintain the high quality and safety standards you expect from a BOSS-equipped rig.

The weld-ready design and durable black finish reflect BOSS’s commitment to longevity, resisting corrosion and wear even under repeated stress and exposure to salt, slush, snow, and winter road debris.

Since the coupler assembly is such a critical junction point — linking frame, hydraulics, and plow blade — installing a genuine BOSS part like CPA04340-03 helps ensure proper alignment, stable mounting, and safe blade action during plowing operations. By staying OEM-compliant, you eliminate many of the risks associated with aftermarket or mismatched parts (e.g., structural stress, misalignment, mounting instability).

Whether you are replacing a worn coupler on a current plow setup or refurbishing an older plow system with RTII mount standards, CPA04340-03 represents a smart, durable investment. Choose this coupler assembly for reliable connection, enhanced structural integrity, and the peace of mind that comes with using a factory-specified BOSS component. Winter’s coming — equip your plow the right way.

NOTE:

In the event that we do not have a BOSS Snowplow item in stock, it will be ordered from the manufacturer. Due to certain regional restrictions, the items will have to arrive here before being sent to you. Ship times will be longer during the Winter season, as demand increases considerably.
