The PSR Heavy Duty Stroker Crankshaft is a precision‑engineered crankcase breather kit crafted from billet aluminum. Finished in a durable black coating, it is designed for a wide range of riding styles—including ATV, off‑road, street, adventure touring, dual‑sport, UTV, snow, and watercraft—ensuring reliable performance across diverse operating conditions. Each unit is a standalone component, making it straightforward to integrate into existing crankshaft and connecting rod assemblies.
Available in two color configurations—CRANK CASE BRTHR DUC BK (black) and CRANK CASE BRTHR DUC RD (red)—the kit offers flexibility for both aesthetic and functional requirements. Its billet aluminum construction provides a balance of strength and weight savings, while the black finish resists corrosion and maintains a clean appearance under harsh riding environments.
