CURT adjustable weight-distribution shank 2" x 2" 10.5" rise / 7" drop — solid-steel, 15,000 lb GTW

CURT 17123 is a heavy-duty, adjustable weight distribution replacement shank that gives precise head-height control with a 10½" maximum rise and 7" maximum drop for 2" trailer receivers.

This solid-steel replacement shank is engineered to restore or upgrade your CURT weight distribution system, letting you fine-tune trailer head height for safer, more balanced towing. Built to fit any CURT WD hitch head, the 2" x 2" receiver shank uses a standard 5/8" pin and offers multiple vertical-hole positions to dial in the trailer and tow vehicle alignment. With a carbide-black powder coat finish and ratings for substantial trailer and tongue loads, this shank is crafted for regular use in tough road and weather conditions.

How does this shank change towing geometry?

The 17123 shank provides multiple vertical positions so you can raise or lower the WD head to correct trailer-to-vehicle rake and balance. Switching between rise and drop orientations alters the relative height of the trailer coupler, helping achieve level towing and correct sway control settings.

• Rise position: up to 10.5" of rise for higher tow vehicles or loaded trailers
• Drop position: up to 7" of drop for lower applications
• 3/4" diameter adjustment holes spaced 1-1/4" center-to-center for fine height increments

Will this shank fit my CURT hitch and receiver?

Yes — the receiver portion is a standard 2" x 2" shank with a 5/8" hitch pin hole, compatible with most CURT Class 3, Class 4 and Xtra Duty Class 5 trailer hitches. The vertical shank is universally sized so it accepts any CURT weight distribution head, making it a straightforward replacement or spare part.

• Receiver size: 2" x 2" with 5/8" pin hole to match common receivers
• Compatible with all CURT weight distribution hitch heads
• Works with many CURT hitch classes for broad interchangeability

What are the load ratings and construction details?

The 17123 is built from high-strength steel and finished with a durable carbide-black powder coat to resist corrosion and wear. It is rated to handle significant towing loads, so you can rely on it for heavy-duty towing tasks and regular use on long trips or tough jobs.

• Tongue weight rating up to 1,500 lbs

How easy is it to install and adjust in the field?

Installation requires only standard hitch tools and a 5/8" pin; the multiple vertical holes let you make quick height changes without complex disassembly. Flipping the shank for rise or drop is straightforward, and the 1-1/4" hole spacing gives predictable incremental adjustments for leveling.

• Fits into any 2" receiver with a 5/8" pin — no special adapters
• Simple flip for rise or drop orientation
• Hole spacing enables repeatable, fine-tuned head-height settings
