   ARP strives to produce the strongest, most reliable, and consistent hardware to meet your racing demands.  ARP2000® bolts are cold forged to ensure molecular integrity, heat treated prior to thread rolling and machining, and designed to exceed the OEM Torque to Yield (TTY) bolts in both strength and durability. 

   Ever wonder why you need to upgrade connecting-rod bolts, cylinder head studs, or other internal engine hardware?  As you demand more horsepower and torque out of an engine it is typically accompanied by higher cylinder pressures, higher RPM running, and greater loads. All these contributing factors can stretch hardware.  Metals are like a spring — put a load on them and they will stretch.  Double the load and they will stretch double.

   Heat treatment is a broad term for the process of heating and cooling metals, while carefully controlling their phase.  This can be done by processes such as annealing in vermiculite, normalizing in air, quenching in water or oil, and a number of other techniques. 








   ARP part # 256-1003 is a new Pro Series ARP2000® Cam Phaser bolt kit for Ford 5.0L Coyote applications.  It includes a set of 12 (M7 x 1.710” U.H.L.).  Also these ARP2000® bolts are nominally rated at 220,000 psi tensile strength and  include a 1/2 oz. pack of ARP Ultra-Torque fastener assembly lubricant. 


  ARP has 2 Carrillo general replacement Pro Series Rod Bolt Kits. Part # 300-6629 is a Carrillo replacement 1/4” ARP 3.5 Rod Bolt Kit. Part # 300-6729 is a Carrillo replacement 1/4” Custom Age 625+® Rod Bolt Kit.  Each kit includes two Carrillo general replacement 1/4” rod bolts and a 1/2 oz. pack of ARP Ultra-Torque fastener assembly lubricant.  Both kits are nominally rated at 260,000 psi tensile strength, impervious to atmospheric corrosion and oxidation.
