Turbo S STS A-Arm Kit
The Lone Star Racing STS A-Arm Kit for the Polaris RZR Turbo S is a race-proven suspension upgrade engineered to replace the factory A-arms with significantly stronger, fully adjustable components. Designed for aggressive trail riding, desert racing, and high-speed off-road abuse, this kit delivers strength, tunability, and confidence where the Turbo S needs it most.
Manufactured from 4130 chromoly steel, these STS A-arms are built to handle extreme loads while remaining lighter and more durable than stock. Heavy-duty uniballs and rod ends replace weak OEM ball joints, eliminating flex and improving steering precision, suspension response, and long-term reliability.
Unlike factory A-arms, the Lone Star Racing STS A-Arm Kit is fully adjustable, allowing you to dial in camber and alignment for different terrains—whether you’re blasting desert whoops, crawling rocks, or pushing race pace. Each kit is race tested and proven, delivering performance you can trust under real-world abuse.
