APEXX Upper Radius Bar Kit Polaris RZR XP 1000 Spherical Bearing – Black (Gloss)

Description

Overview

Tackling rugged off-road trails and punishing terrain demands an unyielding rear suspension setup, and installing the APEXX Upper Radius Bar Kit Polaris RZR XP 1000 Spherical Bearing delivers uncompromising strength to your side-by-side. What this product is: a heavy-duty engineered upper radius bar and suspension link replacement kit built to conquer extreme trail conditions. What it does: it replaces weak factory radius rods with thick DOM steel tubing, locking in precise wheel alignment while incorporating an arched design that yields an extra 1.75 inches of ground clearance over factory specs. Why it is important: OEM factory radius rods are notoriously prone to bending, snapping, or developing excessive slop under heavy loads, large tires, or aggressive driving. Which ATV systems it affects: this component directly integrates with your machine’s ATV Suspension Parts and ATV Drive Train Parts, working seamlessly alongside your rear shocks, hub carriers, and CV axles to maintain stable tracking across rough tracks in the USA, Canada, and throughout North America.

Benefits

Upgrading to this high-performance upper radius bar kit completely transforms your vehicle’s handling stability and structural reliability. The stout DOM steel construction absorbs severe kinetic impacts from hard landings and deep ruts without warping or twisting. By replacing sloppy rubber factory joints with high-grade polyurethane bushings and Teflon-lined spherical bearings, the kit eliminates unwanted play, ensuring immediate steering response and predictable tracking through high-speed corners. Furthermore, the enhanced ground clearance arch prevents obstacles from catching your rear linkage, giving you ultimate confidence during technical trail rides.

Vehicle Compatibility

This precision-engineered suspension upgrade is custom-built for high-performance Polaris side-by-side platforms.

• Compatible Manufacturers: Polaris

• Compatible Models: RZR XP 1000, RZR XP 4 1000

• Compatible Years: Compatible across standard and recent generation RZR XP 1000 lineups (Verify specific submodel year compatibility prior to purchase)

• Common Applications: Extreme trail riding, technical rock crawling, desert overlanding, and mud parks running oversized tires.

Installation Guide

Replacing your rear radius rods requires intermediate mechanical experience and standard hand tools.

• Tools Required: Metric socket and wrench set, torque wrench, floor jack, heavy-duty jack stands, and a drift punch.

• Estimated Installation Time: 1.5 to 3 hours.

• Difficulty: Moderate (rear suspension disassembly and alignment check required).

• Helpful Installation Tips: Safely lift and support the rear of the machine on stable jack stands before removing the wheels to gain clear access to the radius bar mounting bolts. Loosely thread all mounting bolts into place before final torquing to ensure proper alignment. Do not fully tighten suspension hardware until the vehicle is sitting flat on the ground under its own weight to avoid pre-loading or binding the polyurethane bushings.

Signs This Part Needs Replacement

Aggressive off-road use eventually degrades stock suspension linkage. You should inspect and consider upgrading your radius bars immediately if you notice visible bending or cracking in the factory rods, persistent clunking noises coming from the rear end during acceleration or deceleration, sloppy or wandering steering response, or uneven rear tire wear caused by a compromised wheel alignment.

Frequently Asked Questions

Will these radius bars increase my ground clearance?

Yes, the engineered multi-bend arch design provides an additional 1.75 inches of ground clearance right beneath the rear bars compared to stock OEM equipment.

Are the spherical bearings and heim joints replaceable?

Yes, the kit features massive, replaceable Teflon-lined spherical bearings and heavy-duty heim joints, making long-term maintenance simple and cost-effective.

Do I need to buy special adapters to install these?

No, this is a straightforward bolt-on kit designed to fit factory mounting points without requiring major vehicle modifications.

Why are polyurethane bushings better than factory rubber?

Polyurethane bushings are significantly firmer than standard factory rubber, eliminating excess lateral movement and flex to deliver a more responsive, efficient suspension feel.

Will this kit affect my wheel alignment?

The integrated heim joints allow for easy camber and toe adjustability, enabling you to fine-tune your alignment specs precisely after installation.

Can I install these radius bars in a home garage?

Yes, with standard mechanic tools, a reliable floor jack, and jack stands, an enthusiast with moderate mechanical skills can complete the installation at home.

Are these radius bars sold as a complete set?

Yes, this package includes the upper radius bar components required to upgrade the upper rear linkage of your machine.

What maintenance do these spherical bearings require?

Periodically inspect the joints for debris build-up, check all mounting fasteners to ensure proper torque specs, and service or replace wearable components as needed during your regular post-ride cleanup.

Will these bars work with stock portal boxes or lift kits?

Yes, the heavy-duty construction and adjustable geometry are built to handle the added stresses introduced by aftermarket lift kits and portal gear boxes.
