CURT Adjustable Dual-Ball Channel Mount 2" Shank, 6" Drop — Dual 2" & 2-5/16" Balls, Anti-Rattle

The CURT 45900 is an adjustable channel-style dual-ball hitch mount with a 2" x 2" shank that accommodates 2" and 2-5/16" trailer balls and offers up to 5-1/4" rise or 6" drop for precise leveling.

If you tow multiple trailers, a single fixed ball mount can create constant hassle and wasted time. The CURT 45900 eliminates that friction with a heavy-duty, steel channel design that accepts two ball sizes and multiple shank positions so you can quickly configure height and length to match different couplers and trailer weights. Built for durability, it ships with a black carbide powder coat and a dual-pin anti-rattle system to reduce movement and noise on the road.

How does this mount help me level trailers for safe towing?

The adjustable channel shank lets you raise or lower each ball position independently so your trailer tongue sits level with the tow vehicle. Level towing improves handling, reduces sway, and ensures even load distribution across axles.

• Flip shank for a maximum 5-1/4" rise or set for a 6" drop.
• Multiple mounting holes provide precise incremental height adjustments.
• Two hitch-pin hole locations produce usable shank lengths of 11" or 12".

What load capacities does it support and which ball should I use?

This dual-ball platform supports heavier trailers by offering two industry-standard ball sizes with different capacities. Choose the ball that matches your trailer coupler and rated capacity for safe towing within the mount's limits.

• 2" ball rated up to 10,000 lbs gross trailer weight.
• 2-5/16" ball rated up to 14,000 lbs gross trailer weight.
• Channel design accepts additional CURT channel-style accessories if a different ball size or pintle is needed.

How does the anti-rattle and construction extend lifespan and reduce noise?

The channel-style dual-pin mounting clamps the shank and head assembly tightly, minimizing movement that causes clunking and chucking sounds. Rugged steel construction plus a black carbide powder coat give resistance to rust, abrasion, and UV exposure, preserving fit and finish over time.

• Dual-pin mounting system reduces hitch play and road noise.
• Heavy-gauge steel body designed for towing stresses and longevity.
• Black carbide finish offers corrosion and scratch protection.

How versatile is the CURT 45900 for different towing setups?

The open channel permits simple reconfiguration so you can switch between trailers and load types without carrying several separate mounts. It also works with CURT channel-style accessories for added flexibility, such as combination pintle platforms or custom ball sizes.

• Accepts CURT channel-style combination pintle or ball platform attachments.
• Two ball sizes let you tow trailers with differing couplers without swapping mounts.
• Choice of 11" or 12" shank length to suit clearance and load balance needs.

Who this is for: The CURT 45900 is aimed at owner-operators, fleet drivers, and DIYers who tow multiple trailers or change loads frequently and need one reliable mount that covers common coupler sizes and a wide range of trailer weights. If you want fewer parts to manage, adjustable height control, and a durable anti-rattle design that stands up to daily towing, this dual-ball channel mount is built for that purpose.
