ARP Pro Series Performance Head Stud Kit
Pro series cylinder head studs from ARP are cold-forged to ensure molecular integrity.
They are heat-treated prior to thread rolling and machining and are rated at a whopping 200,000 psi for the 8740 material and 220,000 psi for ARP2000.
ARP Pro series kits are also available with 12-point nuts, and all kits come complete with hardened parallel washers for an even load distribution and accurate torque readings.
These are a direct alternative replacement for the stock Mitsubishi torque to Yield factory head bolts which are conmen for stretching and requiring constant replacement.
Use of ARP head studs means stronger engines, less probability of head gasket failure, more compatible with turbo applications etc.
No modifications are required simply remove stock bolts and install at tensions specified by ARP.
