2003-2007 F250 & F350 ARP Main Stud Kit 150-5801

Maximum Durability

When it comes to fastening vital components in your Super Duty, no one does it like ARP. Each stud is manufactured from aircraft quality 8740 heat-treated steel rated at 200,000 psi tensile strength with precision J-form threading for maximum durability and heat resistance. The studs in ARP's Main Stud Kit don't twist into the block allowing for more accurate torque readings, and because a lesser amount of force is being forced on the block thread, you extend block life as well.

Complete Stud Kit

ARP constructed this kit to include everything you'll need for replacing your faulty stock bolts with the improved design and durability of ARP's studs. Along with twenty ARP Pro Series Main Studs, you get twenty 8740 steel 12-point nuts, twenty parallel ground non chamfered washers, eight M12 x 1.50 12-point bolts, eight parallel ground chamfered washers, and a 1 oz. packet of ARP's Ultra-Torque fastener assembly lubricant.
