Polaris RZR Pro R Upper Radius Bar

Upgrade your rear suspension with the Polaris RZR Pro R upper radius bar from High Lifter’s APEXX Suspension Line. Built for aggressive off-road performance, this heavy-duty upper radius bar is designed to deliver increased strength, improved suspension stability, and added clearance over the factory setup. Whether you ride rough trails, mud, rocks, or high-speed terrain, this APEXX radius bar gives your RZR Pro R the durability and control needed for demanding conditions.

Heavy-Duty APEXX Suspension Upgrade

This APEXX upper radius bar for Polaris RZR Pro R is crafted from extreme-duty 1.5″ x .188″ DOM steel, making it up to 50% larger than many stock radius bars. High Lifter added a second bend to increase the arch of the bar, providing approximately 1.75″ of additional ground clearance over the factory arch. The result is a stronger, high-clearance suspension upgrade built for riders who push their machine beyond stock limits.

Key Features

• Extreme-duty DOM steel construction: Built from 1.5″ x .188″ DOM steel for superior strength and durability.
• High-clearance arched design: Added second bend increases clearance by approximately 1.75″ over the factory arch.
• Adjustable heim joints: Replaceable heim joints allow camber and toe adjustment without sacrificing strength.
• Spherical bearings installed: Larger Teflon-lined spherical bearings provide rugged suspension performance.

• Simple bolt-on installation: Designed for quick installation with step-by-step instructions and multi-image guidance.
