Description

The ARP 440-1101 is a specialized header bolt kit engineered for Chrysler Gen III Hemi engines, offering a robust solution for header installation. This kit provides M8 x 1.25 thread size bolts with a precise 30mm underhead length (UHL). They boast a 170,000 psi rating, surpassing the strength of Grade 8 steel. The bolts feature a compact 6-point, 10mm head style that facilitates access with a socket in confined areas adjacent to the exhaust headers. The kit includes premium-quality washers and has a polished finish for corrosion and heat resistance. Each ARP 440-1101 kit contains 16 bolts, sufficient for most header applications on compatible engines. The flanged head design measures 3/8" wide, providing a secure seating surface. These stainless steel bolts are specifically chosen for their durability and resistance to corrosion and extreme temperatures, ensuring a reliable and long-lasting installation.
