RZR 170 Heavy Duty Swing Arm
The Lone Star Racing Polaris RZR 170 Swing Arm is a heavy-duty replacement for the weak factory swing arm, engineered to handle aggressive riding, bigger impacts, and upgraded suspension components. Built from 1 1/4″ 4130 chromoly tubing, this swing arm delivers superior strength and durability compared to stock.
Designed with heavy-duty 3/4″ heim joints, it mounts securely to the frame while providing improved rigidity and reliability. The swing arm is +3/4″ longer than stock, allowing additional clearance for larger diameter shocks and springs—perfect for riders upgrading suspension performance.
The shock mount remains in the stock location, ensuring this swing arm bolts directly onto your RZR 170 with no fabrication required. Engineered axle hub plates allow for easy axle removal, making maintenance quicker and more convenient.
This is a race-inspired upgrade built for kids and youth riders who ride hard and need components that won’t bend, flex, or fail.
