What to Look Out for When Buying Polaris Ranger Engine Replacement Parts?

Engine Upgrade Parts vs Engine Replacement Parts

When something goes wrong with your Polaris Ranger engine, you are faced with a dilemma: Should I go for engine replacement parts or should I also upgrade my engine?

If you choose the former, you are going to retain the same level of reliability and performance of your Ranger which is certainly good enough if you don’t plan on using your Ranger for serious endeavors.

If you choose the latter, you will uncover the world of Polaris Ranger engine upgrades where you can replace what’s wrong while also making your engine perform better.

This is more expensive and requires a broad understanding of what can actually be upgraded in a reliable and safe manner. 

Be that as it may, with only a handful of engine upgrades, your Ranger can become an entirely different beast.

OEM Engine Parts vs Aftermarket Engine Parts

While shopping for Polaris Ranger engine replacement parts (not engine upgrades), you also need to decide if you prefer OEM engine parts over aftermarket parts as there are some pros and cons to each.

OEM parts are usually built to the same standard as the rest of your engine which ensures seamless integration while also saving you time and money when it comes to searching what part works best.

Aftermarket Polaris Ranger engine replacement parts can be both better and worse in all of these categories.

Some higher-end aftermarket part companies will go the extra mile and provide you with an even better component while some, usually cheaper ones, will be far from the OEM level.

To make a sound decision, it would be best for you to browse through our site, compare the prices, read the reviews, and ask the questions you want answered.


The engine is the beating heart of your Polaris Ranger which means that it is a vital organ that provides the necessary ingredients to make your Ranger feel alive.

This only makes sense if your engine works in perfect harmony which is why you should pay extra attention to how to install these parts. 

Some parts such as air filters, spark plugs, oil filters, and ignition coils are very easy to remove and install which is why these can be done in a good old DIY fashion which will help you connect with your machine more.

On the other hand, some parts such as replacing the timing chain, removing the cylinder heads, rebuilding the engine, and changing the turbo are best off left to a professional.
