The component features a meticulously machined design that precisely matches the original equipment manufacturer (OEM) specifications, guaranteeing a seamless fit with the Polaris 800 s suspension system, steering linkage, and frame.

### **Pros and Cons of Buying a Polaris 800 RMK Assault (2011-2015) Lower A-Arm (Right) Part Number: SPI SP-2635-546340**

1. **Compatibility and Fitment** This part is designed specifically for the Polaris 800 RMK Assault model from 2011 to 2015, ensuring a proper fit without modification. It is a lower A-arm (right side), which is a critical suspension component for stability and handling.

2. **Durability and Performance** Polaris parts are generally built to withstand heavy use, making this a reliable component for off-road and aggressive riding. A well-maintained lower A-arm helps maintain suspension geometry, improving ride quality and reducing wear on other suspension parts.

3. **Ease of Installation** Since it is an OEM (Original Equipment Manufacturer) or high-quality aftermarket part, it should be relatively straightforward to install, assuming the buyer has basic mechanical skills or access to a mechanic. Polaris parts often come with clear instructions or are designed to fit without extensive modification.

4. **Resale Value** If the bike is in good condition, a genuine or well-maintained Polaris part like this can retain value, especially if the bike is restored or sold later.

5. **Reliability in Off-Road Use** The 800 RMK Assault is a rugged, high-performance ATV known for its durability in rough terrain. Replacing a worn or damaged lower A-arm ensures continued safe and effective operation in demanding conditions.

6. **Availability of Support** Polaris has a strong dealer network and parts support, making it easier to find replacement parts, service manuals, or technical assistance if needed.

---

- **Wear and Tear:** The part may have been in use for years, especially if it came from a heavily ridden ATV. Inspecting it for cracks, rust, or excessive wear is crucial before purchasing.

- **Obsolescence:** Some newer ATVs may have updated suspension designs, and compatibility with modern accessories or upgrades could be limited.

- **Parts Availability:** While Polaris parts are widely available, some specialized components (especially for older models) may become harder to source over time.

2. **Potential for Hidden Damage** Lower A-arms are prone to bending, cracking, or rust, particularly if the ATV has been ridden off-road or in wet conditions. A visual inspection (or professional assessment) is essential to avoid buying a faulty part.

3. **Cost Relative to Newer Models** If you are replacing this part on an older ATV, the overall value of the bike may be lower than a newer model. The cost of the part itself may not justify the investment if the rest of the ATV is worn out.

4. **Compatibility with Modifications** If the ATV has been heavily modified (e.g., lifted suspension, custom frames), the lower A-arm may not fit as intended, requiring additional work or customization.

5. **Market Demand and Pricing** Older Polaris parts can sometimes be priced higher due to demand from collectors or restorers. However, they may also be cheaper if the part is discontinued or in high supply.

6. **Warranty Limitations** Unless purchased new from an authorized dealer, this part may not come with a warranty. Aftermarket parts may have limited or no warranty, leaving the buyer responsible for any failures.

Buying a Polaris 800 RMK Assault lower A-arm (right) from 2011-2015 can be a practical choice if you need a reliable, OEM-quality part for your specific model. It is a critical suspension component that, when in good condition, will significantly improve ride quality, safety, and longevity of your ATV. However, the age of the part and model means you must carefully inspect it for damage, verify its condition, and consider whether the overall health of your ATV justifies the purchase.

If you are restoring or maintaining an older ATV, this part is a solid investment. If you are looking to upgrade to a newer model or replace multiple worn components, weigh the cost against the value of the entire ATV.

---

- Check for cracks, rust, or bending in the A-arm. A slight bend may be fixable, but severe damage will require replacement.

- Ensure the part matches your ATV s year and configuration (left vs. right, lower vs. upper A-arm).

- If possible, have a mechanic verify the part s condition and compatibility.

- If budget allows, explore newer Polaris parts or high-quality aftermarket alternatives (e.g., from brands like **Fox, RockShox, or Spawn**) that may offer improved durability or warranties.

- If your ATV is heavily modified, ensure the part will fit without conflicts.

- Purchase from an authorized Polaris dealer, trusted online retailers (e.g., **ATV Parts Pro, Polaris Outdoors, or eBay with seller reviews**), or a reliable mechanic who can guarantee authenticity.

- Avoid parts with unclear histories or those that appear to have been salvaged from unknown sources.

- If the rest of your ATV is worn out (e.g., suspension, engine, frame), replacing just the lower A-arm may not be cost-effective. Consider whether restoring the entire ATV or upgrading to a newer model is more practical.

- If you lack mechanical experience, factor in labor costs for professional installation to ensure proper alignment and safety.

This part is a **good purchase** if you need a direct replacement for your 2011-2015 Polaris 800 RMK Assault and can verify its condition. However, if the ATV is beyond its prime or you are open to upgrades, prioritize the overall health of the vehicle before investing in individual components. Always prioritize safety and functionality over cost savings.
