ARP Head Stud Kit — Honda/Acura B16

Upgrade your B-series build with ARP’s premium head stud kit, engineered for superior strength and precision over factory head bolts. Each stud is made from 8740 chromoly steel and heat-treated to 190,000 psi tensile strength for dependable clamping under high boost, high compression, or extended track use. Threads are rolled after heat treatment for maximum fatigue resistance, while the undercut design helps equalize load across the head to reduce distortion and improve gasket sealing.

Switching to studs instead of bolts gives you:

• More consistent and accurate torque readings

• Even clamping force across the cylinder head

• Easier alignment during head installation

• Reusable design for long-term reliability

• Improved head gasket sealing under extreme conditions

Includes 12-point hardened nuts, parallel-ground washers, and ARP Ultra-Torque lubricant for precise installation.

Fits:
Honda B16A / B16A2 / B16A3 / B17A

Note: This kit is not compatible with Honda B18C1 (GSR) heads. For B18C1 / B18C5 applications, use ARP 208-4303.
