Heat soak kills starters silently: the solenoid absorbs radiant heat from the exhaust and engine block, internal components expand and bind, and the motor refuses to crank when you need it most. The Heatshield Products Stealth Starter Shield wraps around big-body, pre-1990s starters and blocks up to 1200°F of continuous radiant heat, keeping the solenoid cool enough to function reliably even in low-airflow engine bays.
Made from crushed volcanic rock fiber. The basalt-based material handles 1200°F continuous and 2000°F intermittent radiant heat without degrading. It resists water, chemicals, and acids, so underhood fluids and road grime do not compromise the shield over time.
Non-conductive construction protects electrical components. Unlike metallic heat shields, the basalt fiber material cannot short an exposed terminal if it makes contact with the starter or solenoid wiring. That matters in tight engine bays where clearances are minimal.
Installs without removing the starter. The shield wraps around the motor and secures with heavy-duty hook-and-loop fasteners included in the kit. Most installations take only a few minutes, and the fastener system holds firm against engine vibration and heat cycling over years of service.
Stealth black finish suits any build. The 501570 ships in a black Stealth finish sized at 7-1/4 in x 21-3/4 in, matched to big-body starters from pre-1990s applications. It blends into dark engine bays and delivers the same thermal performance as the natural Lava variant.
Product Benefits
- 1200°F Continuous Rating: Blocks sustained radiant heat from exhaust manifolds, headers, and the engine block.
