Grandroad Auto 30" Stainless Steel Mud Flap Hanger Set for Semi Trucks — Spring-Loaded, 3×4" Light Cutouts

This pair of straight-style mud flap light bars combines corrosion-resistant stainless steel with a spring-loaded design to protect your mud flaps and reduce shock from rough roads. Each bar measures 30 inches and includes three 4-inch cutouts for tail or marker lights, plus matching reflective strips; lights are not included. The bars are engineered for semi trucks and use 2.5-inch bolt spacing to fit common mounting studs—measure your vehicle before buying.

How does the spring-loaded design improve durability on rough routes?

The integrated spring mechanism lets the hanger give under impact and rebound, cutting down on transmitted force that can bend brackets or rip mud flaps. That flexibility reduces long-term stress on mounting points and helps keep lights aligned on bumpy surfaces.

• Spring-loaded pivot absorbs shocks from potholes and curbs
• Lowers vibration to extend fastener and light lifespan
• Stainless steel construction resists rust in wet environments

Will these bars fit my semi truck and lights?

Each hanger is 30 inches long with 2.5-inch spacing between the mounting bolts—matching many standard truck studs. There are three 4-inch light cutouts spaced along the bar to accept round or rectangular tail/marker fixtures, but confirm your light dimensions before ordering.

• 30" overall length for common trailer and tractor applications
• 2.5" bolt spacing fits many industry mounting studs
• Three 4" cutouts provide mounting spots for additional lighting

How simple is installation and what hardware is included?

Installation is straightforward: position the hanger, align the studs through the predrilled holes, and secure with the supplied nuts. The package is designed to save time with only basic tools required; wiring for lights is not included and must be done separately.

• Comes with matching nuts for fast, straightforward assembly
• Mounting studs accept standard wrenches—no specialty tools needed
• Reflective strips included; lights and wiring are not supplied

How do these hangers enhance safety and visibility?

The built-in three light cutouts let you add extra tail or marker lights for improved rear visibility, and the reflective strips increase detection in low-light conditions. Together these features help other drivers see your vehicle more clearly, especially in poor weather or at night.

• Three light openings for supplemental illumination options
• Reflective strips improve passive visibility without power
• Elevates both safety and the vehicle's finished appearance
