Paradise Racing Exclusive!!!
ARP PRO 1/2" Head Stud Kit for Toyota Tacoma 2RZ & 3RZ engines.
These are are custom made for Paradise Racing!!!
These are a great step in between the standard size ARP Head Studs and our L-19 1/2" head studs!!!
These are the ones you MUST use if you plan on running more than 35-40 psi!!!
These are 1/2" size and require modifications to your head & block!!!
Your head will have to be drilled and your block will have to be drill and tapped for 1/2" threads.
Engineered for high boost applications, these Pro series 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 190,000 psi. The 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.
We have used these head studs to support 60psi!!!
