ARP SB Chevy LSA ARP2000 Hex Head Bolt Kit

This is the ARP 234-3603 ARP2000 Hex Head Bolt Kit, specifically for SB Chevy LSA engines. ARP is well-known for making strong fasteners, and this kit uses their ARP2000 material, which is a high-strength alloy that offers improved performance over standard Grade 8 bolts. If you're rebuilding the top end of your LSA engine, these bolts are a solid choice for ensuring everything stays securely in place under pressure.

The ARP2000 material is heat-treated and aged to achieve its high tensile strength, rated at 220,000 psi. This means they can handle the increased clamping forces and stresses found in performance LSA applications. The hex head design is also a practical feature, as it often allows for easier access and installation in tight engine bays compared to traditional stud and nut configurations. When you're putting your engine back together, using reliable fasteners like these from ARP is crucial for long-term durability and performance.
