Polaris RZR Pro R Lower Arched Radius Bar

Upgrade your rear suspension with the Polaris RZR Pro R lower arched radius bar from High Lifter’s APEXX Suspension Line. Built for riders who demand strength, control, and durability, this lower radius bar is designed to replace weaker factory components with a heavy-duty suspension upgrade. Its arched design helps improve clearance in tough terrain, while the reinforced construction gives your RZR Pro R the support needed for aggressive off-road riding.

Heavy-Duty APEXX Suspension Performance

This APEXX lower arched 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. The upgraded design uses larger spherical bearing housings, massive 7/8″ heim joints, and 7/8″ Teflon-lined spherical bearings to deliver the strength and serviceability needed for demanding trail, mud, dune, and high-speed use.

Key Features
