Tired of that annoying rattling and clunking from your hitch when you're towing? These hitch tighteners are the perfect solution! You get two in the pack (red and black) that work with both 1.25\ and 2\ hitches - perfect for Class I through IV receivers. The heavy-duty drop forged steel construction can handle serious weight and vibration without failing. The rubber isolator acts as a cushion to prevent metal-on-metal contact that causes all that noise. Installation is straightforward: just slide the U-bolt through your hitch, add the washers and locking nuts, and tighten everything down with the included wrench. The powder-coated finish resists rust and corrosion, so these will last through all kinds of weather conditions. Perfect for eliminating noise from bike racks, cargo carriers, trailer balls, or any hitch-mounted accessory. The dual locking nuts with nylon inserts ensure everything stays tight mile after mile. No more listening to that annoying clunking every time you hit a bump or make a turn. Your trailer towing experience will be so much quieter and more pleasant with these simple but effective stabilizers installed.
