Black Friday Doorbuster Arp Head Stud Kit For Honda Civic Si 2017-2021 (l15b7) Limited Time 65% Off [6goGrKY5]

Throughout our extensive experience in engineering high-performance, low-displacement 4-cylinder engines, we've consistently recognized the critical importance of maintaining robust head-to-block sealing. For this purpose, ARP head studs stand unmatched. Currently, there isn't a ready-made kit for the L15B7 engine, but by integrating select ARP components with custom-designed spacers, we've developed a solution that meets both our requirements and those of others.

ARP selects top-grade 8740 alloy for their studs, which undergoes a rigorous heat treatment process to reach a tensile strength of 200,000 psi, ensuring thorough heat penetration and a quality far surpassing that of inferior studs found in the market, which are often processed inadequately.

After heat treatment, ARP takes the additional step of centerless grinding each stud to achieve unparalleled concentricity. This meticulous process, involving around ten fine adjustments, yields a product of exceptional straightness.

Moreover, ARP's method of thread rolling the studs post-heat treatment significantly enhances their fatigue strength by approximately 1000% compared to those threaded before heat treatment, a prevalent but inferior industry method. Despite the higher cost due to the wear on tools, this process is a testament to ARP's commitment to excellence.

Key Features:
- ARP head studs for unmatched reliability.
- Made from 8740 chromoly steel with 12-point nuts for superior strength.
- Includes a correctly sized spacer to ensure accurate torque application of the head studs.

Benefits:
- Provides a higher clamping force to maintain seal integrity.
- Offers enhanced resistance to head lifting in high-boost scenarios, ensuring engine durability and performance.
