Connecting Rods 2022-20224 Polaris Pro R

Kraftwerks Performance Connecting Rods are forged from aircraft quality 4340 chromoly steel and feature an FEA optimized H-beam design for excellent strength-to-weight ratio. Forging improves rod strength, fatigue resistance, and dimensional stability by aligning the material grain flow with the shape of the rod. Additionally, Kraftwerks connecting rods are heat treated and shot peen stress relieved before final honing. Each rod comes standard with high strength ARP 2000 rod bolts (220,000psi) and will support approximately 200hp per cylinder.

Note: for ultra-high horsepower applications up 250hp/cyl, we recommend using ARP 625+ (290,000psi) bolts.
