Briggs & Stratton Heat Shields
Briggs & Stratton heat shields are essential protective components that safeguard surrounding parts from extreme exhaust temperatures. Our range includes engine heat shield guards, lawn mower heat shield assemblies, exhaust heat shield deflectors, and Briggs & Stratton exhaust heat shield replacements in both metal and composite materials. These muffler guards and deflectors protect plastic components, fuel lines, carburetors, and grass from direct heat exposure while redirecting hot exhaust gases safely away from critical areas. Suitable for push mowers, riding tractors, generators, and pressure washers across all Briggs & Stratton engine applications. We hold stock worldwide.

Frequently Asked Questions
How do I install a replacement heat shield correctly?
Most heat shields mount using existing threaded studs or bolt holes on the engine block or muffler assembly. Clean mounting surfaces thoroughly before installation to ensure proper heat transfer and secure fitment. Position the shield according to directional indicators or alignment tabs, ensuring adequate clearance from the muffler surface—typically 1-2 inches air gap for optimal heat dissipation. Torque mounting bolts finger-tight initially, verify proper positioning, then tighten securely without overtightening thin metal. Check that shields don't contact moving parts or obstruct airflow paths.
Is it safe to run my engine without the heat shield?
Running without a heat shield creates serious safety hazards. Mufflers reach temperatures exceeding 1200°F during operation, hot enough to melt plastic components, ignite dry grass clippings on the deck, burn grass beneath stationary equipment, and cause carburetor vapor lock from excessive heat. Missing heat shields also expose operators and bystanders to severe burn risks from accidental contact with hot exhaust components. Replace damaged or missing heat shields immediately before operating equipment to prevent fire hazards and component damage.
What components do heat shields protect from exhaust heat?
Heat shields primarily protect carburetors, fuel lines, air filter housings, plastic shrouds, electrical wiring, drive belts, and nearby grass or debris from direct muffler heat. The carburetor requires particular protection as excessive heat causes fuel vaporization leading to hard starting and performance issues. Deflectors also redirect exhaust gases downward away from the deck, preventing dry grass accumulation that creates fire hazards. On riding mowers, heat shields protect operator platforms and frame components from sustained high-temperature exposure.
What's the difference between heat shields, muffler guards, and deflectors?
These terms describe slightly different protective components. Heat shields are flat or curved metal plates mounted between the muffler and vulnerable components to block radiant heat. Muffler guards wrap around or over the muffler providing physical protection from impact damage while also deflecting heat. Deflectors attach to the muffler outlet directing exhaust gases in specific directions away from sensitive areas. All serve protective functions but differ in mounting location and primary purpose—some focus on heat management while others combine heat protection with physical shielding.
Can I make a temporary heat shield from other materials?
In emergency situations, automotive-grade aluminum flashing from hardware stores can provide temporary protection when properly mounted off the muffler surface. High-temperature header wrap tape designed for automotive exhaust systems offers another short-term solution. However, fabricated shields rarely match OEM specifications for clearances, mounting points, and heat resistance. Genuine replacement parts ensure proper fitment, correct material specifications, regulatory compliance, and warranty coverage. Temporary solutions should only be used until proper OEM replacements are obtained to maintain equipment safety and performance.
