Arp Head stud made of ARP2000 material custom milled for the G4fj and G4fc motors

Available on backorder


As you know stretching the head bolts on these motors is very common. For any of you that want to get more power this is a must to save your motor from head gasket failures due to lifted heads.  This Hyundai/Kia ARP Head Stud Kit – 1.6L Gamma engines kit by Kdm Tuners are customized and ready to drop in. We mill two nuts down to 1.17″ to clear the HPFP lobe and cam sensor lobe on the camshaft, this is mandatory to do or you will destroy your motor right on start up. We also have you guys and girls reuse the factory washers, this is not because we are lazy or cheap no… This is because the factory washer actually gives more spread of the load allowing for better clamping power. The Arp washers are smaller in diameter and wont do what the factory washers do. We also include ARP lube and full instructions with our kits.

    Had’ the original stud set not have a defect, we would’ve given you a higher score. But drop shipping a replacement was a game changer. Well done.

    Customer service was great. I had a head gasket leaking on a rio and wasn’t sure if the head stud kit would work on it and I wanted the reassurance it wouldn’t leak. They were able to tell me what parts would and wouldn’t work that I was intrested in for the repair. Stud kit came with good instructions. Car is back on the road.

    10/10 Didn’t feel like popping the head off, so I replaced them one by one, Works great, No lifted heads perfect for those trying to push stock limits.
