CURT 45110 Trailer Ball Mount for 2" Receiver — 10" Drop / 8" Rise, 5,000 lb GTW, Gloss Black

CURT 45110 is a Class 3 ball mount that fits 2" receivers, offers a 10" drop (8" rise when flipped), and supports up to 5,000 lbs gross trailer weight in the drop position.

This heavy-duty ball mount is made for trucks and SUVs with a 2" x 2" trailer receiver that need a reliable, corrosion-resistant towing attachment. Built using CNC forming and robotic welding, the mount is mechanically descaled and finished with a gloss black powder coat to resist scratches and rust. It accepts a standard 1" ball shank and gives you adjustable height options so you can level a wide range of trailers safely within component limits.

How does this ball mount help level my trailer?

The CURT 45110 gives two practical height options to get your trailer level relative to your tow vehicle: a 10" drop when installed one way, and an 8" rise when flipped. Proper leveling improves towing stability and loading, and selecting the correct orientation helps maintain recommended tongue weight and visible clearance.

• 10" drop position for low trailers and lower coupler heights
• 8" rise position for taller trailers or vehicles with lift kits
• 13" overall length for balanced leverage and clearance
• Accepts a 1" ball shank (ball sold separately)

What towing capacities and safety limits should I expect?

In the drop orientation this mount is rated for 5,000 lbs gross trailer weight (GTW) and 500 lbs tongue weight (TW). When flipped to the rise orientation the capacity is reduced—3,500 lbs GTW and 350 lbs TW—so always follow the lowest rated component in your towing system, including vehicle, hitch, ball, and trailer ratings.

• 5,000 lbs GTW and 500 lbs TW in 10" drop
• 3,500 lbs GTW and 350 lbs TW in 8" rise
• 1" ball hole to accept common trailer ball sizes
• Never exceed the lowest-rated towing component

What construction and corrosion protection does it offer?

CURT machines and welds each mount using CNC forming and robotic welding for consistent fitment and strength. After mechanical descaling for a smooth surface, a gloss black powder coat is applied to protect against road chips, UV, and rust—extending service life and maintaining appearance under regular use.

• CNC-formed and robotically welded for consistent strength
• Mechanically descaled for a smooth finish and adherence
• Durable gloss black powder coat resists corrosion and scratches
• Hollow shank reduces weight and accepts anti-rattle kits

How does fitment and installation work for this model?

The CURT 45110 is designed for any 2" x 2" receiver and slides into place using a standard hitch pin and clip (not included). Its hollow shank keeps weight down and allows aftermarket anti-rattle hardware to be used; measure coupler height and choose drop or rise orientation to achieve level towing before fastening the trailer ball.

• Fits standard 2" x 2" receiver tubes
• Uses 1" ball hole for common trailer balls (ball not included)
• 13" overall length for proper clearance and fitment
• Compatible with anti-rattle kits for a tighter connection

Who this is for: The CURT 45110 is aimed at truck and SUV owners who tow medium-duty loads like boats, campers, utility trailers, and ATVs and need a dependable, corrosion-resistant Class 3 ball mount with adjustable height. Choose this mount if you want precision manufacturing, a durable powder-coated finish, and the flexibility of drop or rise positions—just be sure to match the mount’s ratings with your vehicle, hitch, and trailer limits.
