CHDT66 Mud Flap Hangers 30.25" Square Steel Pair — Heavy-Duty, Hardware Included

CHDT66 mud flap hangers are a ready-to-install, heavy-duty pair of 30.25" square-steel bars with brackets and hardware to secure standard semi truck mud flaps.

Built for professional trucking and fleet maintenance, these hangers provide a durable, corrosion-resistant mounting solution for 24"-wide mud flaps up to approximately 5/8" thick. The kit arrives complete with two cast-steel mounting bases, a pair of straight horizontal bars, and all required fasteners so you can replace worn hangers or fit new flaps without sourcing extra parts.

How do these hangers fit my truck?

The hangers use a common bolt pattern and include two cast-steel mounting base brackets with 1.875" center spacing so they align with many semi truck mounting points. The horizontal orientation and standard hole spacing simplify installation on compatible frames and brackets.

• Horizontal bar length: 30.25" for adequate flap coverage.
• Bolt hole center spacing: 1.875" on the cast steel bases.
• Designed to match common semi truck mounting patterns.
• Includes all mounting hardware to avoid extra parts purchases.

What size and thickness of mud flaps will these hold?

These hangers are sized for mud flaps about 24" wide and accommodate flap material up to roughly 5/8" (16.5 mm) thick. Each bar is equipped with four flap clips—one fixed and three adjustable—to fit different flap edge thicknesses and fastening styles.

• Recommended flap width: 24" (~61 cm).
• Maximum flap thickness: ~5/8" (16.5 mm).
• Clip configuration: 1 fixed clip, 3 adjustable clips per hanger.
• Clip adjustability allows use with a variety of flap materials.

How rugged and long-lasting are these components?

The main bar is a 0.640" square steel profile engineered for heavy-duty use, and the kit includes cast-steel mounting bases for enhanced durability where stress concentrates. The materials and construction are chosen to withstand road vibration and typical fleet wear when installed correctly.

• Bar type: 0.640" square steel for stiffness and impact resistance.
• Mounting bases: cast steel for long-term strength.
• Hardware included to ensure solid, vibration-resistant attachment.
• Straight bar orientation reduces debris catch and simplifies maintenance.

The package contains one pair of mud flap hangers, two cast-steel mounting brackets, and the complete set of mounting hardware plus adjustable clips. Installation is direct: line up the mounting bases with your vehicle’s bolt pattern, secure the brackets, attach the bars, and fasten the flap clips.
