ARP Triumph TR4 12pt Head Stud Kit

Made from ARP's proprietary 8740 chromoly steel, these head studs offer a significant upgrade over stock bolts for your Triumph TR4 engine. The 12-point nuts provide a more secure and even clamping force, which is crucial for maintaining a good seal between the cylinder head and the engine block, especially under higher performance conditions or when rebuilding the top end.

ARP is well-known for making strong, reliable engine fasteners. These studs are heat-treated to achieve a tensile strength of 200,000 psi, ensuring they can handle the stresses of your engine. The kit includes the necessary nuts and washers, all made to ARP's exacting standards, so you can be confident in their performance and durability. If you're looking to ensure your cylinder head stays securely in place, this kit is a solid option.
