Rod Bolt Kit - Honda / Acura K20A

The ARP Rod Bolt Kit for Honda/Acura K20A engine (part 208-6003) is an essential upgrade for serious K-series builders who are pushing their engines beyond OEM limits. This kit is ideal for those assembling high-revving track engines, building boost for forced induction, or simply seeking enhanced reliability from a modified K20A. Rod bolts are a critical component in ensuring the engine can handle increased combustion pressures and temperatures.

ARP rod bolts are crafted from premium alloy steel, offering superior yield strength and fatigue resistance compared to factory fasteners. The fasteners undergo shot-peening to improve their resistance to cyclic loading, and ARP's proprietary heat-treat process guarantees consistent clamp load across all bolts in the kit. Designed for precise installation, these bolts utilize the stretch-bolt method, which involves a torque-and-angle procedure to achieve accurate preload, ensuring the rod cap remains securely seated.

Enthusiasts rebuilding K20A engines for road racing, autocross, or street performance will find this kit indispensable, especially when integrating modified internals with ECU tuning and higher boost levels. The kit includes all necessary fasteners for complete K20A crankshaft assembly, along with ARP lubricant to ensure proper installation and maximize bolt life.
