HKS: HEAD STUD PRO FOR NISSAN SKYLINE GT-R BNR34 RB26DETT
We are releasing "reinforced head stud bolts" to prevent gasket leaks caused by the head bolts stretching due to high combustion pressure in hard-tuned engines.The car was evaluated through real-world testing in a rigorous drag race at an ultra-high output of over 1,200 horsepower.Taking into account the high power output of recent RB26 tuning, this product is made of "Custom Age 625+" material , which has the highest tensile strength, and is an original HKS design that is a bottom-attached type to reduce damage to the block ."Custom Age 625+" is the material with the highest tensile strength among ARP's products, and has excellent fatigue cycle life and corrosion resistance. It has 1.3 times the tensile strength of "ARP2000", which prevents problems such as gasket loss even under high combustion pressure.By using bottom-mounted stud bolts, the effective thread on the block side becomes longer, dispersing stress and reducing the likelihood of cracks occurring around the screw holes on the deck surface of the block.By reducing the risk of cracks, it also contributes to extending the life of your valuable cylinder block. It is also recommended for general overhauls.By using this product together with any HKS head gasket, you can achieve a higher sealing effect. For those who are aiming for high power or who drive on a circuit, we recommend using it in combination with the "Grommet Type Metal Head Gasket Super Cooling".
