HD Upper A-Arms for Pro R & Turbo R

The Polaris PRO R / Turbo R HD Upper A-Arms by Lone Star Racing are built for riders who demand maximum strength, precision alignment control, and long-term durability from their suspension. Constructed from high-strength 4130 chromoly steel, these heavy-duty upper A-arms are a significant upgrade over the factory components.

Designed as a direct bolt-on replacement, these arms retain OEM mounting locations while dramatically increasing strength and adjustability. Featuring a combination of 3/4″ and 7/8″ rod ends, they allow for precise camber and caster adjustments, making it easy to dial in your suspension for aggressive trail riding, desert racing, or high-speed off-road use.

Race tested and engineered to withstand extreme abuse, these HD upper A-arms eliminate flex found in stock arms, improve front-end stability, and maintain proper alignment under load—giving you more confidence at speed and through rough terrain.
