Protect your boosted or high-compression Nissan KA24E (SOHC 2.4L) engine with the ultimate in head-to-block clamping security: the ARP Head Stud Kit (P/N: 202-4307). A must-have upgrade for any serious performance build, these Pro Series head studs are engineered to eliminate head lift and prevent blown head gaskets under extreme conditions, especially in turbocharged or supercharged Nissan 240SX (S13/S14) and Hardbody Truck applications.

Factory head bolts are not designed to withstand the increased cylinder pressures of high-performance tuning. ARP's world-renowned Pro Series head studs solve this problem, ensuring your cylinder head remains perfectly sealed to the block for reliable power.

Why Choose ARP 202-4307 Head Studs?

• Superior Strength: Manufactured from premium 8740 Chromoly steel and heat-treated to an impressive 200,000 psi tensile strength.

• Optimal Clamping: The studs are thread-rolled after heat treatment, yielding ten times better fatigue strength than bolts threaded beforehand, resulting in more accurate and consistent clamping force.
• Precision Fitment: Designed specifically for the Nissan KA24E 2.4L SOHC engine, guaranteeing perfect alignment of the head and gasket.
• Complete Kit: Includes all the necessary components: twelve-point black oxide finished nuts, and hardened parallel-ground washers for even load distribution and precise torque readings.
• Application: Essential upgrade for Nissan 240SX S13/S14 owners and builders running the KA24E (SOHC) engine at elevated boost levels or high RPM.
