CURT 2" Ball Mount Class III 45090 — Reversible 6" Rise / 8" Drop, 5,000 lb GTW, Gloss Black

CURT 45090 is a Class III 2" ball mount that gives you a reversible 6" rise or 8" drop with up to 5,000 lb gross trailer weight capacity when used in the drop position.

This solidly built ball mount is designed for trucks and SUVs that use a 2" x 2" receiver. CNC-formed and robotically welded, the CURT 45090 delivers consistent fit and strength while the gloss black powder coat helps resist corrosion and road wear. The hollow 11-1/2" shank reduces weight and accepts a standard 1" ball shank, and the reversible design lets you level trailers without adapters.

How does the rise/drop feature help with trailer leveling?

The CURT 45090 flips to provide two different mounting heights so you can achieve a close-to-level tow without stacking shims or using multiple accessories. This versatility supports a wider range of tow vehicles and trailers, simplifying setup before each trip.

• 8" drop position for lower trailers and trailers that sit below the truck bed.
• 6" rise position for taller trailers or when the tow vehicle sits lower than the trailer.
• Reversible design removes the need to carry extra mounts for different trailers.

What load ratings and safety limits does this ball mount have?

In the drop orientation the mount is rated for up to 5,000 lb gross trailer weight (GTW) and 500 lb tongue weight (TW); flipped to the rise position it is rated to 3,500 lb GTW and 350 lb TW. Always observe the lowest rated limit among vehicle, hitch, ball, and trailer components to avoid overloading.

• 5,000 lb GTW / 500 lb TW in drop configuration.
• 3,500 lb GTW / 350 lb TW in rise configuration.
• 1" hole to accept standard trailer ball shanks; check your ball size and ratings.

What construction and finish features affect durability and fit?

CURT uses CNC forming and robotic welding to produce precise geometry and repeatable strength, while mechanical descaling prepares the surface for coating. The gloss black powder coat provides a tough barrier against rust, chipping and UV exposure so the mount stays serviceable season after season.

• CNC-formed body for consistent dimensions and fit in the receiver.
• Robotic welding for uniform welds and structural integrity.
• Gloss powder coat finish for scratch and corrosion resistance.

How does the hollow shank benefit everyday towing?

The hollow 11-1/2" shank keeps weight down while maintaining strength, making handling and installation easier. Its internal cavity also allows use with anti-rattle kits that fit inside the shank to reduce noise and movement between mount and receiver.

• 11-1/2" overall length balances ground clearance and towing stability.
• Hollow design reduces weight without sacrificing rated capacity.
• Compatible with internal anti-rattle accessories for a firmer hitch fit.

Who is this for? The CURT 45090 Class III 2" ball mount is aimed at pickup and SUV owners who need a dependable, reversible mount for medium-duty towing — from utility and boat trailers to campers and small horse trailers. It suits drivers who want a precisely made, corrosion-resistant mount that fits a 2" receiver and works with common 1" ball shanks. Remember to match this mount's ratings to the weakest component in your towing system and follow safe towing practices.
