MZS Adjustable Trailer Hitch for 3.0-Inch Receiver — 8" Adjustable Drop/Rise, 21,000 lb GTW, Dual Chrome Balls

The MZS Adjustable Trailer Hitch is a heavy-duty, CNC-machined aluminum tow mount that fits 3.0-inch receivers and provides up to 8 inches of adjustable drop or rise with dual chrome-plated ball mounts.

This adjustable ball mount combines a high-strength aluminum body with chrome steel tow balls and a patented quick-adjust mechanism so you can fine-tune towing height in one-inch increments. Engineered to a 21,000 lb gross towing weight (GTW), it accommodates common ball sizes and a broad range of trailers while minimizing corrosion and wear. Before ordering, confirm your vehicle has a 3.0-inch receiver; this product is designed specifically for that size.

How does the MZS hitch let me change towing height quickly?

Adjustment is handled by a patented indexed system that allows smooth, one-inch step changes across an 8-inch rise or drop. A keyed locking pin secures the selected position to prevent shifting during travel.

• 8 inches total adjustment: up to 8" rise or 8" drop
• 1-inch increment indexing for precise leveling
• Keyed lock to secure the chosen height
• Patent-design mechanism for fast, repeatable changes

What towing capacity and ball sizes does it support?

The MZS adjustable hitch is rated to tow up to 21,000 lbs GTW when used within a compatible vehicle and trailer setup. It comes with two integrated, chrome-plated balls so you can swap between standard coupler sizes without additional hardware.

• Maximum GTW: 21,000 lbs (verify vehicle and trailer limits)
• Built-in 2.0" and 2-5/16" tow balls for common coupler sizes
• Chrome-plated steel balls for durability and smooth coupler contact
• CNC-machined mating surfaces for reliable load transfer

Is the MZS hitch durable and weather resistant?

The main body is precision CNC-machined from heavy-duty aluminum for a high strength-to-weight ratio and natural corrosion resistance. Critical wear parts—like the tow balls—are chrome-plated steel to resist pitting and preserve coupler engagement under repeated use.

• Aluminum body resists rust and reduces weight
• Chrome-plated steel tow balls for long-lasting surface integrity
• Precision machining ensures tight fit and minimized play
• Designed for reliable performance in demanding conditions

How do I know this hitch fits my vehicle?

• Compatibility: only for 3.0" receiver tubes — measure first

• Works with trailers that match the included ball sizes
• Ensure correct hitch pin size and safety chain attachment
