Rock Tamers RT231 Heat Shield, Stainless Steel Heavy-Duty Mudflap Heat Guard with Ceramic Washers

Rock Tamers RT231 Heat Shield is a heavy-duty stainless steel add-on that protects mudflaps from hot exhaust and lets you mount mudflaps closer to tailpipes safely.

Designed as an accessory for the Rock Tamers mudflap lineup, the RT231 provides a durable barrier against high exhaust temperatures so you can position your mudflap system nearer to the tailpipe without heat damage. Constructed from 1.0 mm stainless steel and supplied with ceramic "top hat" washers and all necessary fasteners, this shield balances robust protection with simple, adaptable installation.

How does the RT231 shield reduce heat risk to my mudflaps?

The RT231 intercepts and disperses radiant and convective heat from nearby exhausts, lowering the temperature that reaches the mudflap material. Its stainless steel face creates a thermal barrier while ceramic washers protect the flap at attachment points from concentrated heat.

• 1.0 mm stainless steel construction for heat reflection and durability
• Ceramic “top hat” washers to insulate mounting points
• Design allows heat to dissipate away from the mudflap surface

Will it fit my existing Rock Tamers system and where can it mount?

The RT231 is compatible with Rock Tamers systems 00108, 00110, and 00112, and it can be positioned anywhere on the mudflap to suit vehicle layout and exhaust location. The hardware package supports flexible placement so you can adapt installation to single or dual tailpipe configurations.

• Works with Rock Tamers 00108, 00110, 00112 (mudflap systems sold separately)
• Mounting hardware included for varied orientations
• Can be installed along the flap edge or closer to the centerline as needed

What comes in the box and how easy is installation?

The RT231 ships with a full hardware kit and a compact steel wrench so you have every part needed for mounting. Installation is straightforward and the product packaging includes instructions on the back to guide a quick setup by a DIYer or a technician.

• Includes one stainless heat shield and complete fastener kit
• Contents: 4 M6 star pin steel bolts, 4 ceramic washers, 8 M6 steel washers, 4 M6 steel/nylon nuts, 1 steel wrench
• Instructions printed on back of packaging for step-by-step guidance

How does the RT231 improve durability and longevity of mudflaps?

By diverting heat away from rubber or polymer mudflap material and by isolating the mounting points, the shield reduces thermal stress and potential material degradation. The stainless steel face also resists corrosion and physical wear, adding a protective layer against road debris and heat cycling.

• Stainless construction resists rust and abrasions
• Ceramic washers reduce localized heat damage at fasteners
• Compatible with various mounting positions to minimize wear patterns

Who is this for: The RT231 is intended for truck, trailer, and heavy-duty vehicle owners who use Rock Tamers mudflaps and need reliable thermal protection near exhaust outlets. It’s suited to fleet operators, off-road users, and anyone who wants to place mudflaps closer to tailpipes without sacrificing material life. Note that the RT231 is an accessory—Rock Tamers mudflap systems are required but sold separately.
