CURT Adjustable Hitch Shank 2" Receiver — 12" Length, 8-7/8" Rise / 5-5/8" Drop, 15,000 lb GTW

CURT 17120 is a heavy-duty, adjustable replacement shank that lets you set rise or drop for a precise weight distribution hitch fit.

Built to restore or upgrade your weight distribution setup, this CURT replacement shank provides a durable, adjustable connection between a 2" receiver and CURT weight distribution heads. Constructed from solid steel with a carbide black powder-coat, the shank resists corrosion and wear on the road. It accepts standard 2" x 2" receiver openings with a 5/8" hitch pin and is compatible across CURT's class 3, class 4 and Xtra Duty class 5 hitch lines.

How does this shank adjust rise and drop for trailer leveling?

The vertical portion of the 17120 features multiple 3/4" holes spaced 1-1/4" center-to-center so you can move the weight distribution head up or down in precise increments. Flip the shank orientation to switch between a maximum rise of 8-7/8" and a maximum drop of 5-5/8" to match trailer and tow vehicle geometry.

• Maximum rise position: 8-7/8" for raising the trailer tongue
• Maximum drop position: 5-5/8" for lowering the trailer tongue
• Hole spacing: 1-1/4" centers for fine height tuning
• Hole diameter: 3/4" for secure WD head mounting

What receiver and hitch systems is this compatible with?

The shank inserts into any standard 2" x 2" receiver using a 5/8" hitch pin hole, making it suitable for most CURT trailer hitches and many aftermarket receivers. It’s designed specifically to work with all CURT weight distribution heads so you won’t need adapters to pair it with CURT WD systems.

How does installation and adjustment work in practice?

Adjusting head height only requires removing the head hardware, selecting the appropriate 3/4" hole for the desired height, and reattaching—no special tools beyond standard hand tools are needed.
