12-Point Flywheel Bolt Kit

The ARP Pro Series flywheel and flexplate bolt kit plays a critical role in the performance and safety of both race and street cars. Engineered by ARP, these fasteners are a significant upgrade over standard OEM hardware. Each bolt is forged from a high-strength aerospace alloy and undergoes a rigorous heat-treatment process before thread rolling and machining, ensuring exceptional durability and reliability. This kit features ARP's exclusive, flat 12-point head design, which offers superior engagement for your socket compared to traditional 6-point heads. Additionally, these bolts boast a larger than stock shank diameter, providing increased tensile strength and a more secure flywheel register. The black oxide finish adds a layer of corrosion resistance. Key specifications include a 10mm x 1.25 thread size and an overall length underhead (UHL) of 1.050 inches. The 12-point, 1/2-inch wrench head ensures a secure fit for installation. This kit is specifically designed for the Toyota 4AGE 1.6L DOHC engine.
