CURT trailer balls are designed to be high-quality and a perfect fit for your coupler and ball mount. As such, we thought it fitting to back them up with a variety of accessories to maximize their potential and improve your overall towing experience. Whether you are installing a brand new trailer ball or simply looking for a little equipment upkeep, CURT has accessories and replacement parts to get the job done.

Our trailer ball hex wrench is constructed from forged, hardened steel and has a durable chrome plating. It features two different ends to fit two trailer ball nut sizes: 1-1/8" or 1-1/2". It can be used on trailer balls with either 3/4" or 1" shanks and has a 6-point hex design for a better hold on the nut compared to 12-point wrenches. The CURT trailer ball wrench is the perfect installation tool to quickly get your trailer ball mounted and your trailer hitched up.
