Polaris RZR PRO XP Lower Arched Radius Bar | Spherical Bearings

Polaris RZR PRO XP Lower Arched Radius Bar

Upgrade your rear suspension with the Polaris RZR PRO XP lower arched radius bar from High Lifter’s APEXX Suspension Line. Built for riders who need more strength, better clearance, and improved suspension control, this heavy-duty lower radius bar is designed to replace weaker factory components with a stronger, adjustable, trail-ready upgrade.

High-Clearance APEXX Suspension Upgrade

This APEXX Polaris RZR PRO XP Lower Arched Radius Bar 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 in the bar to increase the arch, giving your RZR PRO XP approximately 1.75″ of additional ground clearance over the factory arch. That extra clearance helps your machine move through ruts, rocks, mud, and rough trail obstacles with more confidence.

Key Features

• Extreme-duty DOM steel construction: Built from 1.5″ x .188″ DOM steel for serious off-road strength.
• Lower arched design: Adds approximately 1.75″ of ground clearance over the stock lower radius bar.
• Spherical bearings installed: Includes larger extreme-duty spherical bearings for rugged suspension performance.
• 7/8″ heim joints: Massive replaceable heim joints allow camber and toe adjustability without sacrificing strength.
• 7/8″ Teflon-lined spherical bearings: Built for durability, serviceability, and smooth suspension movement.
• Polyurethane bushings: Firmer than rubber to help reduce excess movement and improve suspension response.
• Simple bolt-on kit: Designed for straightforward installation with step-by-step multi-image instructions.

Why Choose This Polaris RZR PRO XP Lower Arched Radius Bar?

Factory lower radius bars may limit clearance and may not provide the strength needed for hard trail riding, mud, rocks, and high-speed terrain. This High Lifter APEXX lower radius bar improves durability with DOM steel construction, spherical bearings installed, massive 7/8″ heim joints, and firmer polyurethane bushings. The result is a professional-grade suspension upgrade designed to reduce unwanted movement, improve stability, and keep your RZR PRO XP ready for demanding rides.

Installation Note: Always check bearing and brake wear before installation. Replace worn parts before installing this lower radius bar to help ensure proper suspension performance.
