The Lone Star Racing Polaris RZR XP Turbo STS A-Arm Kit is engineered for riders who demand more strength, more control, and more confidence on every terrain. Designed as a direct replacement for the factory A-arms, this STS kit is built from high-quality 4130 steel—one of the strongest materials used in performance suspension systems. Whether you're carving dunes, blasting desert trails, or pushing hard through rocky terrain, these A-arms deliver the durability and impact resistance your RZR XP Turbo needs to perform at its best.
Equipped with heavy-duty uniballs, the STS A-Arm Kit provides superior articulation and increased stability under load. This design enhances suspension geometry, giving you sharper steering response, better cornering ability, and reduced body roll during aggressive maneuvers. The result is a smoother, more predictable ride that keeps your machine planted and in control when conditions get rough.
Installation is simple thanks to the direct-fit design and included hardware. No wheel modifications or additional upgrades are required—your factory wheels remain fully compatible. Riders looking to elevate their RZR XP Turbo’s performance will appreciate the combination of strength, precision, and long-term reliability Lone Star Racing delivers.
If you’re ready to upgrade your suspension with a proven, race-inspired component, the LSR STS A-Arm Kit offers the perfect balance of durability and performance for any off-road enthusiast.
