Convert-A-Ball interchangeable trailer shank 1" with 3 balls (1-7/8", 2", 2-5/16") nickel-plated, 10,000 lb capacity

The Convert-A-Ball 900B is a nickel-plated interchangeable trailer shank with a 1" diameter that ships with three tow balls for versatile hitching up to a 10,000 lb. gross trailer weight.

Designed to simplify towing by letting you swap ball sizes quickly, this Convert-A-Ball 900B shank pairs durable chrome-plated steel construction with corrosion resistance. The kit includes 1-7/8", 2", and 2-5/16" balls and fits a 1" diameter mount, making it a compact, all-in-one solution for drivers who tow different trailers or need a rugged replacement part.

Which trailers and tongues will this 1" shank work with?

This shank is suited for couplers that accept standard tow balls and for vehicles or adapters designed around a 1" diameter shank. It’s commonly used with light- to medium-duty trailers where the combined towing system does not exceed the product’s rated capacity.

• Compatible with couplers requiring 1-7/8", 2" or 2-5/16" balls
• Fits mounts and receivers built for a 1" shank diameter
• Best for trailers within the 10,000 lb. gross trailer weight limit
• Works with standard aftermarket hitch adapters and Convert-A-Ball systems

How does the 900B handle corrosion and everyday wear?

The shank and balls are chrome/nickel plated over solid steel to resist rust and keep surfaces smooth for easier coupling. That plating helps maintain appearance and function in wet or salty environments, reducing maintenance compared with bare steel parts.

• Chrome-plated solid steel construction for durability
• Nickel finish resists surface corrosion and pitting
• Smoother surfaces reduce binding during coupling and uncoupling
• Requires only routine inspection and lubrication of contact points

What towing capacity and physical dimensions should I expect?

The 900B shank is engineered with a 10,000-pound gross trailer weight rating when used as specified by your towing system. The shank measures 1" in diameter and 2-1/4" in overall length, providing a compact footprint while accommodating three common ball sizes for flexibility.

• Shank diameter: 1" for standard mounts
• Shank length: 2-1/4" for secure insertion depth
• Towing rating: up to 10,000 lb. gross trailer weight
• Included balls: 1-7/8", 2", and 2-5/16"

How easy is it to change balls and maintain the system?

Swapping between the three included balls is a straightforward process that requires only removing the securing pin or fastener and replacing the ball as needed. Regular visual checks for wear, proper torque on retaining hardware, and light lubrication of moving surfaces keep the system reliable.

• Quick-change design for fast ball swaps in the field
• Simple retaining-pin or bolt removal—no complex tools needed
• Inspect for cracks, deformation, or excessive corrosion before each trip
• Apply light lubricant to keep ball/hardware moving smoothly

Who is this for: The Convert-A-Ball 900B is aimed at vehicle owners, fleet operators, and DIY trailer owners who need a durable, interchangeable tow solution that covers multiple ball sizes without carrying several separate hitches. It’s ideal for those who switch between trailers often, require corrosion resistance, and want a compact, high-capacity shank that integrates with standard 1" mount systems.
