CHDT66 Mud Flap Hangers for Semi Trucks – 30.25" Square Steel Bar, Heavy-Duty Kit with Cast-Steel Brackets

CHDT66 mud flap hangers are a heavy-duty 30.25" square-steel pair designed to mount and secure standard 24" semi truck mud flaps, supplied with brackets and all required hardware.

These mud flap hangers deliver a straightforward, rugged mounting solution for trucks, trailers, and other heavy vehicles. Built from 0.640" square steel and supplied as a complete kit, they remove the guesswork from installation and provide multiple clip positions to fit different flap thicknesses. The package contains two hangers, two cast-steel mounting base brackets, and the bolts and fittings you need to attach them to common bolt patterns.

How do these hangers fit my semi truck?

The hangers are engineered to match common semi truck bolt patterns with 1.875" center spacing on the cast steel mounting bases. The horizontal mounting hole orientation and included brackets allow straightforward attachment to frames or crossmembers that use the same pattern.

• Horizontal bar length: 30.25" for broad coverage.
• Mounting base spacing: 1.875" hole centers to fit standard holes.
• Includes two cast-steel brackets to mate with typical frame plates.

Will my mud flaps work with these hangers?

Yes — the kit is designed for mud flaps about 24" wide and up to 5/8" thick. Each hanger has four flap clips: one fixed clip and three adjustable clips so you can position the flap precisely and secure different flap profiles.

• Compatible flap width: ~24" (61.0 cm).
• Maximum flap thickness: approximately 5/8" (16.5 mm).
• Clip configuration: 1 fixed, 3 adjustable for flexible fit.

What materials and durability features are included?

The hangers are made from 0.640" square steel that offers strength against vibration and road stress. The cast-steel mounting bases provide a robust anchor to vehicle frames, and the included hardware is selected to complete a secure installation without sourcing extra parts.

• Bar type: square steel, 0.640" thickness for rigidity.
• Mounting bases: cast steel for long-lasting strength.
• Hardware: complete set included so you can install immediately.

How simple is the installation process?

The kit is shipped with all necessary fasteners and brackets for a direct-fit installation when your vehicle matches the stated mounting hole pattern. Basic hand tools are typically sufficient, and the adjustable clip positions reduce the need for drill modifications or custom fabrication.

• Tools required: common wrenches and sockets for supplied bolts.
• Pre-drilled holes: mounting base uses 1.875" center spacing.
• Adjustable clips: minimize trimming or re-drilling of flaps.
