Why Add RZR Wheel Spacers?
RZR wheel spacers are precision-machined components designed to mount between your wheel hub and the wheel itself. They effectively increase your vehicle's track width, pushing the wheels further out from the suspension. This modification is a popular choice for RZR owners seeking improved handling, enhanced stability, and greater clearance for larger tires or aftermarket suspension components. The primary benefit is a wider stance, which directly translates to reduced body roll and a more planted feel, especially during aggressive cornering or on uneven terrain. They are a cost-effective way to gain significant performance advantages without altering fundamental suspension geometry.
- Increase track width for better stability.
- Improve clearance for larger tires and suspension.
- Reduce body roll during aggressive maneuvers.
- Cost-effective performance enhancement.
When considering wheel spacers for your Polaris RZR, understanding their purpose is paramount. They aren't just aesthetic; they serve a functional role in optimizing your ATV's footprint. A wider stance created by properly selected RZR wheel spacers can dramatically alter how your machine handles challenging off-road conditions. This involves considering the material, thickness, and mounting style to ensure they meet your specific needs and driving style.
Core Benefits of a Wider Stance
The most immediate advantage of installing RZR wheel spacers is the dramatic improvement in stability. By extending the track width, you lower the vehicle's center of gravity relative to its base of support, making it far less prone to tipping or rolling over. This is particularly vital when navigating steep inclines, off-camber trails, or high-speed desert runs. Beyond stability, they provide essential clearance. If you're upgrading to larger, more aggressive tires, spacers can prevent rubbing against suspension components or fenders, allowing you to utilize the full potential of your tire choice without modification to the vehicle's bodywork.
Understanding how these components work is fundamental. They create space, allowing components to operate without interference. It is imperative to acknowledge that improper installation or using low-quality spacers can lead to premature wear on bearings or studs, undermining the very performance you seek.
Key Considerations Before You Buy
Selecting the right RZR wheel spacers involves more than just picking a thickness. Material quality is paramount; typically, CNC-machined billet aluminum is the standard for its strength, light weight, and corrosion resistance. Hub-centric designs are highly recommended over lug-centric ones, as they ensure the spacer is centered on the vehicle's hub, reducing vibration and stress on wheel studs. Thickness is also critical – a 1.5-inch or 2-inch spacer is common for general use, while custom widths might be needed for specific tire setups or extreme builds. Always ensure the bolt pattern (e.g., 4x156 for many RZRs) and the hub bore diameter match your vehicle precisely. For instance, 8x6 5 wheel spacers or 5x4 75 wheel spacers are for different vehicle types and not typically for RZRs, which usually feature a 4x156 bolt pattern.
Such precision is paramount for safe operation and longevity. The wrong fitment can lead to catastrophic failure.
Measure your existing setup and consult your RZR's manual or a reputable dealer to confirm exact hub bore and bolt pattern specifications before purchasing any wheel spacers.

The Best RZR Wheel Spacers for 2024
Based on these criteria, here are our top recommendations:
| Brand/Model | Thickness | Material | Key Feature |
|---|---|---|---|
| SuperATV (+2" Spacers) | 2 inches | Billet Aluminum | Hub-centric, heavy-duty hardware |
| High Lifter (+1.5" Spacers) | 1.5 inches | Aircraft-Grade Aluminum | Precision fit, corrosion-resistant |
| EMP (+1.5"/2" Spacers) | 1.5 or 2 inches | T-6 Billet Aluminum | Optimized for RZR fitment, includes studs |
| Pro Armor (+2" Spacers) | 2 inches | Machined Aluminum | Aggressive styling, robust construction |
Each of these options provides a significant upgrade over stock, offering enhanced stability and clearance. For example, the SuperATV 2-inch spacers are a go-to for riders looking to significantly widen their RZR's stance for maximum stability on challenging trails. If you're aiming for a more moderate increase or need a precise fit for specific tire sizes, the High Lifter or EMP kits are excellent choices. Pro Armor offers a blend of aggressive looks and proven performance.
The goal is a wider, more stable footprint that inspires confidence on any terrain.
When selecting, consider the specific model of your RZR, as fitment can vary slightly. A 2-inch spacer, for instance, provides a substantial increase, ideal for fitting 33-inch tires or larger. For those running slightly smaller upgrades or wanting a less aggressive stance, 1.5-inch RZR wheel spacers offer a balanced improvement.
Always check the included hardware for thread pitch and length to ensure it's compatible with your specific RZR's wheel studs and torque specifications.
Installation and Comparison
What does it take to install RZR wheel spacers, and how do they stack up against each other? The installation process is generally straightforward, making it an accessible upgrade for most DIY enthusiasts. However, precision and attention to detail are critical for safety and performance. Understanding how to install wheel spacers correctly ensures you maximize their benefits and avoid potential issues.
The Installation Process
Installing RZR wheel spacers typically involves these steps: First, ensure your vehicle is safely supported on jack stands and the wheels are removed. Clean the mounting surface of the wheel hub thoroughly to remove any dirt or debris that could affect the spacer's seating. Place the wheel spacer onto the hub, aligning the bolt holes. If you have hub-centric spacers, ensure they seat flush against the hub. Then, reinstall the wheel. Start the lug nuts by hand to avoid cross-threading, and then torque them to your vehicle's specifications in a star pattern. It is imperative to re-torque the lug nuts after a short ride (e.g., 25-50 miles) to account for any settling.
This mechanism is critical for ensuring the wheel is properly secured. Always refer to the manufacturer's specific instructions, as details can vary between kits and RZR models.
Comparing Spacer Types and Materials
The primary distinction lies in material and design. Billet aluminum is the industry standard for good reason: it's strong, lightweight, and resistant to corrosion. Machined from solid blocks, these spacers offer superior durability compared to cast aluminum or steel alternatives. Hub-centric designs are superior because they use the vehicle's hub bore to center the spacer, distributing load evenly and preventing vibrations. Lug-centric spacers rely solely on the lug nuts for alignment, which can lead to uneven stress and potential issues over time.
For specific applications, you might encounter specialized spacers. For instance, while not common on RZRs, terms like 8 lug wheel spacers or 8x170 hub centric wheel spacers refer to heavy-duty truck applications. Similarly, 5x4 wheel spacers and 5x4 5 wheel spacers are for different vehicle bolt patterns. For RZRs, focusing on 4x156 bolt pattern spacers is key. Thickness is also a major differentiator; 1.5-inch and 2-inch are the most popular for RZRs, offering a good balance for increased stability and tire clearance without excessive stress on suspension components. Thicker spacers, like 3-inch or more, are usually reserved for custom builds and can significantly impact steering geometry and component wear.
It is fundamental to select spacers that match your RZR's bolt pattern precisely, such as the common 4x156 configuration. Mismatched patterns can be extremely dangerous.
When comparing the top picks, the main differences often come down to the grade of aluminum used, the quality of the included hardware, and the precision of the machining. SuperATV and High Lifter are well-regarded for their robust, hub-centric designs and inclusion of high-quality studs and nuts. EMP often focuses on OE-like fitment, while Pro Armor might offer slightly more aggressive aesthetics alongside their performance.
The primary consideration involves ensuring the chosen spacers are compatible with your RZR model and intended use. A common mistake is not accounting for the increased leverage placed on wheel bearings and suspension components by wider offsets.
