Jeep 4.0 Intake and Exhaust Manifold ARP® Stud Kit With Chromoly Cone Washers

This kit uses genuine ARP® studs and nuts along with our hardened chromoly cone washers for uniform clamping force and increased durability.  ARP® hardened studs prevent stretching and loosening even in the harshest conditions.  Our custom-made chromoly cone washers are designed to be thicker and harder than the stock washers.  The cone design allows for thickness variations between the intake manifold and header flanges.
