CURT 2" Stainless Steel Trailer Hitch Ball 6,000 lb, 1" Shank — Corrosion-Resistant, Fine-Threaded

This tow ball blends durable stainless-steel construction with fine-threaded attachment hardware so you can connect trailers quickly and confidently. Engineered and tested to U.S. VESC specifications, the CURT 40053 aims to deliver consistent performance for trucks and SUVs using class 3 or class 4 hitches. Its compact shank and corrosion-resistant finish make it suitable for frequent use in varied weather without excessive wear or rust.

How does the 40053 hold up to corrosion and rough conditions?

The CURT 40053 uses stainless steel for the ball and polished finish to resist rust from road salt, rain and mud. That material choice reduces maintenance and preserves appearance even after repeated exposure to the elements. Stainless construction also minimizes pitting and surface degradation compared with plain steel options.

• Stainless steel ball and polished finish for long-term corrosion resistance
• Controls rust and surface wear in harsh driving conditions
• Lower maintenance compared to non-stainless tow balls

Will this ball fit my trailer and hitch setup?

The 40053 is engineered with a 2" ball diameter to match virtually any standard 2" coupler. Its shank diameter is 1" with a 2-1/8" length, designed to seat securely through common ball-mount plates. Always verify that your vehicle, hitch, and trailer components each meet or exceed the needed capacity before towing.

• 2" ball diameter for standard 2" coupler compatibility
• 1" shank diameter and 2-1/8" length for common ball-mount plates
• Fits class 3 and class 4 hitch assemblies on many trucks and SUVs

What safety and installation features does it include?

The ball comes with a zinc-plated hex nut and helical lock washer, plus fine threads to maximize holding strength when torqued. CURT tests this model to U.S. VESC standards, ensuring consistent manufacturing quality and predictable performance. Installation requires correct torque (refer to your vehicle and hitch specifications) to achieve full rated capacity.
