Key Features & Benefits

Premium ARP Stainless Steel Construction: ARP stainless steel header bolts are engineered to be 15 percent stronger than Grade 8 steel, giving your exhaust installation a serious strength upgrade. The stainless construction also provides excellent resistance against corrosion, heat, and harsh underhood conditions.
Compact 12-Point Head Design: The 12-point head allows for improved socket engagement while using a smaller tool footprint in tight spaces. This is especially helpful around Gen V LT headers where frame rails, steering components, plug wires, and primary tubes can make standard bolt access difficult.
Polished Stainless Finish: The polished stainless steel finish provides a clean, professional look while helping fight rust and surface corrosion. This makes the kit a strong choice for both show-quality engine bays and hard-working performance builds.
Built for Header Installations: Designed specifically for header and exhaust manifold fastening, these bolts are a dependable upgrade when replacing worn, rusty, rounded, or missing factory hardware. Proper header hardware helps support consistent clamping force and a cleaner exhaust installation.
Vehicle-Specific Gen V LT Fitment: This ARP 434-1103 kit is built for Chevrolet Gen V LT 5.3L and 6.2L applications and includes the correct 10-bolt quantity for compatible engines. It is ideal for LT truck, SUV, swap, and performance applications using compatible header or exhaust manifold setups.
