Demimy 24-Inch Stainless Steel Mud Flap Weights Pair with Backing Plates — Corrosion-Resistant, Ready-to-Install

Demimy 24-inch stainless steel mud flap weights are a heavy-duty pair with reinforced backing plates and mounting hardware designed to keep semi-truck mud flaps stable and reduce road spray.

These 24-inch mud flap weights from Demimy are built for commercial trucks and long-haul rigs that need reliable, corrosion-resistant hardware to hold mud flaps in place under wind, highway speeds, and harsh weather. Each kit includes two weights, matching backing plates, and a full set of stainless mounting hardware so you receive a ready-to-install solution that fits most semi-trailer and large commercial vehicle mud flaps.

How do these weights stop mud flaps from sailing up at high speeds?

The weights add downward force along the bottom edge of the mud flap while the backing plates stiffen the mounting area, preventing the flap from folding or inflating in crosswinds. Together they stabilize the flap profile so it maintains contact with the road and blocks spray.

• 24.5" x 4.5" x 1.5" stainless steel weights for consistent downward pressure
• Reinforced stainless backing plates increase structural rigidity where bolts pass through
• Designed to reduce road spray and debris by up to 70% when properly installed

What materials and finish protect these weights from rust and corrosion?

Demimy uses heavy-gauge stainless steel with a silver powder-coated finish to resist salt, water, and grime rather than thinner plated metals that degrade faster. The backing plates and included hardware are corrosion-resistant stainless steel, so the entire attachment point remains durable over years of exposure.

• 2.1 mm stainless steel construction resists corrosion in wet and salty conditions
• Powder-coated silver finish provides extra barrier against scratches and oxidation
• All included bolts, nuts, lock washers, and flat washers are stainless and long-lasting

How easy is installation and what tools are required?

The pair ships with pre-drilled holes and all required fasteners, enabling a bolt-on installation that most technicians can complete quickly with common hand tools. No welding or custom fabrication is needed; simply align, secure the backing plate, and tighten the supplied hardware to recommended torque specs.

• Includes 6 bolts, 6 nuts, 6 lock washers, and 6 flat washers for a secure mount
• Pre-drilled mounting holes cut installation time and eliminate drilling errors
• Standard wrenches or a socket set are sufficient—no specialty tools required

Will these weights fit my truck’s mud flaps and fleet specifications?

These weights are designed for universal fitment to 24" wide mud flaps used across major truck brands and trailers. Their bolt-on approach and compact profile makes them adaptable to most semi-trailers, box trucks, and other large commercial vehicles without modification.

• Compatible with 24" mud flaps on Peterbilt, Freightliner, Kenworth, Volvo, Mack, and similar brands
• Compact dimensions fit tight mounting locations while delivering effective weight distribution
• Pair packaging and individual backing plates allow use on single or dual-flap applications

Who is this for: Fleet managers, professional drivers, and maintenance crews who need a rugged, low-maintenance solution to keep mud flaps functional and reduce road spray. If you operate long-haul rigs, work in snowy or coastal regions, or want to lower debris-related maintenance costs, this Demimy kit provides a durable, simple-to-install upgrade that lasts through heavy use.
