Turbo S STS Trailing Arms
The Lone Star Racing STS Trailing Arms for the Polaris RZR Turbo S are a heavy-duty, direct bolt-on replacement for the factory trailing arms, engineered to deliver superior strength, reliability, and off-road performance.
Manufactured from 4130 chromoly steel, these STS trailing arms are designed to withstand aggressive riding, hard landings, and demanding terrain that can quickly overwhelm OEM components. A massive 3/4" heavy-duty rod end replaces the weak factory joint, significantly improving durability while reducing flex and deflection under load.
Designed as a direct OEM replacement, these trailing arms maintain proper suspension geometry while dramatically increasing strength—making them ideal for high-speed desert riding, trail abuse, and performance-focused Turbo S builds.
