Polaris RZR 900 XP Engine Rebuild Service (2013–2014)
We guarantee your engine will be as good as new. Every REV6 engine includes a 1-year no-fault warranty. Additionally, you can upgrade to a 2-year no-fault, no-questions-asked warranty for $450. If anything happens during that time, we will repair or replace your engine—no questions asked. That means real protection and real peace of mind.
At REV6, we focus on quality control and consistency. Every part, engine, and transmission goes through a detailed inspection and rebuild process. As a result, you get an engine built for reliability, performance, and long-term use.

Quality Control Process
Every engine goes through multiple inspections by master technicians. In addition, one technician builds the engine and another inspects it before it leaves our shop. This double inspection process helps ensure your engine performs as expected.
With over 60 years of combined Powersports experience, our team understands what it takes to build reliable engines.
Core Requirement & Shipping
To complete your rebuild, we require your engine core. You can either send your core in first or choose a refundable $1200 core charge option.
If your core is in rebuildable condition, the charge is fully refunded. For preparation steps, review our shipping instructions. You can also find additional details in our Help Center.
Performance Upgrades Available
Looking for more power? We can help. Whether you want a mild upgrade or a more aggressive setup, our team can recommend options that match your riding style and goals.
Looking for Parts Instead of a Full Engine?
Not every build requires a complete engine rebuild service. In some cases, rebuild kits or specific components may be the better option.
If you plan to rebuild the engine yourself or only need certain parts, browse our Polaris RZR parts and rebuild kits. Additionally, you can view options for the 2013–2014 RZR 900.
This includes top-end kits, bottom-end kits, gasket kits, transmissions, and other components designed for DIY builds and shop installs.
Lead Time
Most engine rebuilds ship within 5–10 business days after your core is received. However, lead times may vary depending on workload and parts availability.
Order with Confidence
If you have questions about your build, warranty options, or core requirements, contact our team. Otherwise, secure your rebuild and get your machine back on the trail.
