ARP Head Stud Kit, Volvo B21 / B23 / B230 8V Engines

ARP Head Stud Kit – Volvo B230 Engines

Upgrade the reliability of your Volvo redblock engine with this premium ARP head stud kit designed for all B230-series engines. Perfect for performance builds, turbo conversions, higher boost levels, or simply ensuring long-term sealing under demanding conditions.

Factory head bolts on the B230 are torque-to-yield and can stretch under high cylinder pressure, leading to head gasket failure. ARP studs eliminate this issue with unmatched clamping force, high-strength materials, and reusable hardware that delivers consistent torque and superior durability.

Key Features

• High-strength ARP 8740 chrome-moly steel studs
• Far superior clamping force compared to OEM bolts
• Perfect for turbo, high-boost and high-compression engines
• Reusable – maintains torque accuracy run after run
• Heat-treated, centerless ground and precision-threaded
• Includes studs, washers, and 12-point ARP nuts

Volvo B230-series engines, including:
B230F / B230FT / B230FK / B230FB / B230FD and other redblock variants.
