Brian Crower BC6079 ProH2K Connecting Rods ARP2000 Set of 4 Honda K20C1 CTR

Vehicle Fitment

• 2017-2021 Honda Civic Type R (FK8, K20C1 2.0L Turbo I4, FWD)
• 2023-2026 Honda Civic Type R (FL5, K20C1 2.0L Turbo I4, FWD)
• 2023-2026 Acura Integra Type S (DE5, K20C8 2.0L Turbo I4, FWD)
• 2018-2022 Honda Accord 2.0T (CV2, K20C4 2.0L Turbo I4, FWD)

Fitment Notes

• ARP2000 fasteners included - rated for builds up to approximately 700 hp. For builds targeting 900+ hp, see BC6078 with ARP Custom Age 625+ fasteners.
• The Acura Integra Type S (DE5) uses the K20C8 engine, which is mechanically identical to the K20C1 in all internal dimensions; BC6079 fits both platforms.
• Bushed for full-floating piston pin - aftermarket pistons with floating pin design are required if OEM pistons use a pressed-fit pin.
• Sold as a set of 4 - covers all connecting rods for the 4-cylinder K20C engine.

Features

• CNC machined from aerospace-grade 4340 chromoly steel and micropolished for superior surface finish, fatigue resistance, and long-term durability under high boost.
• H-beam design provides exceptional tensile strength and beam rigidity under sustained high-RPM and high-boost K20C1 operating conditions.
• Aluminum/silicone/bronze pin bushings support full-floating wrist pin operation, reducing pin stress and improving pin lubrication.
• Finish-honed big end bore to exacting tolerances ensures precise bearing clearance and consistent oil film across all four rod journals.
• 3/8" ARP2000 rod bolts deliver reliable clamping force for builds up to approximately 700 hp, with a proven track record in forced induction K-series applications.
• Micropolished beam surface reduces stress concentration points and improves oil shedding within the crankcase.

Product Description

The Brian Crower BC6079 connecting rods are a direct-application ProH2K H-beam rod set for the Honda K20C1, K20C4, and K20C8 2.0L turbocharged inline-four - the engine family powering the Civic Type R FK8 and FL5, the Acura Integra Type S, and the Honda Accord 2.0T. CNC machined from 4340 chromoly steel and micropolished, these rods replace the OEM connecting rods on K20C builds pushing past the limits of stock internals. The H-beam design balances tensile strength with lateral rigidity, making it well suited to the sustained boost pressures and RPM demands of the K20C platform. ARP2000 hardware provides reliable clamping force for builds up to approximately 700 hp.

Full-floating aluminum/silicone/bronze pin bushings distribute wrist pin load evenly across the pin bore and improve lubrication compared to pressed-pin OEM rods - requiring aftermarket pistons with a floating pin design. Each rod is finish-honed to precise bearing clearance tolerances and sold as a complete set of four with all hardware included. Builders targeting 900+ hp can opt for BC6078, which is the same rod fitted with ARP Custom Age 625+ fasteners.
