Polaris Ranger RZR 800 Air Box $259.95

All CFM Performance products are proudly Made In USA.

Will fit any year RZR 800.

Made from the highest quality materials including 0.083" 5052 series aluminum, 0.125" extruded 6061 series mounting bracket, and stainless steel hardware. 

The stock air box uses a tiny 2 1/2" paper filter. It is too small and loads up with dirt too easy. The plastic lid on the stock box holds the filter in place. It is known to wear out easily, causing the filter to come loose. This allows dirt into the motor and ruins it. 

This air box uses a HUGE 4 1/2" filter that is clamped to a heavy duty aluminum ring. 4 times more dirt holding capacity. No chance of it coming loose. The panel on the left side of the air box can be removed to replace the filter and clean the inside of the air box. The front panel/ lid has an opening at the top where air comes in. Both panels are sealed to the rest of the box with water resistant neoprene rubber. 

Leave the front panel/ lid in place for a 1-2 horsepower increase on an otherwise stock machine. Remove the lid for a 3-6 horsepower increase on a stock machine. With the addition of a fuel management unit and a good exhaust system this air box is good for 10 horsepower.

 Uses UNI filter NU-4140ST and K&N filter part number RU-3480.

Your stock air box has the crank case breather hose attached to it. This air box allows for so much air flow that the crank case breather hose can not be attached to the air box because it can actually suck oil out of your crank case and into the air box. We leave the breather hose open and tie it to the frame in the highest location it will reach. We have run our ATV's with an open breather hose for many years, in all riding conditions with no problems. The crank case maintains positive pressure on the hose making it virtually impossible for anything to get in. The open crank case breather hose has been standard on many ATV's for years. If you would like more protection, you can add a crank case breather filter to the hose.

Polaris RZR Lift Kit $19.95


All of our products are proudly 100% Made in the USA.

CFM Performance has been serving the powersports community since 1993. 

You can buy from us with confidence knowing that we will be here after the sale.

Everything that we sell is our own original design. 

Beware of cheap imitations, every other eBay seller selling these has copied our idea, design and many have even stolen our installed picture.




Item For Sale:

Will fit any year Polaris RZR 570 and RZR 800.

Will fit any year Polaris Sportsman XP850 and XP1000.



Features and Benefits:

Will give you about 2" of lift depending on model and shock settings.

They are sold in sets of 4 spacers, 1 for each shock.

Will work with stock shocks only.

Made from 7075 series aluminum. The same strength as steel, but lighter and much more corrosion resistant.

Ride quality is similar to stock.

Still have the ability to adjust preload.

Eliminates sag in the stock springs.

Drastically reduces brake dive and corner roll.

Increases load capacity. 

No modifications are necessary to any of your stock components.

Spring compression is required. You will need a coil spring compressor or other method of compressing the springs.



How it Works:

A 1" spacer lifts the machine about 2" because of the geometry of progressive rate suspension. With stock springs, the weight of the machine will compress the springs about 1", lowering the machine about 2". With this lift installed, the weight of the machine will not compress the springs as much, resulting in an increase in ground clearance of about 2". 


Installation Instructions:

Remove the shocks from your Polaris. Compress the springs. There is a "C" shaped collar that holds the spring to the shock body. When you compress the spring, this "C" shaped collar will fall off. Slide the lift spacer on the shock body and replace the "C" shaped collar. Reinstall the shock.

Polaris Ranger RZR 570 Aluminum Intake Air Box Airbox 2-6 HP $259.95

All CFM Performance products are proudly Made In USA.

Will fit any year RZR 570.

Made from the highest quality materials including 0.083" 5052 series aluminum and stainless steel hardware. 

Comes with everything you need. No extra items to buy. No modifications are required. Install in about 30 minutes with basic hand tools. 

The stock air box uses a restrictive flat paper filter. It is too small and loads up with dirt too easily. The stock paper filter is easy to tear. The plastic lid on the stock box is supposed to hold the filter in place, but you never know if it is sealed properly. This allows dirt into the engine and ruins it. 

This air box uses a 4" I.D. filter that is clamped to a heavy duty aluminum ring. It has 2 times more dirt holding capacity than the stock filter and there is no chance of it coming loose or allowing dirt to pass. 

This air box comes with 2 different lids. Both lids are sealed with water resistant neoprene rubber. One lid will seal the top of the air box completely, just like your stock air box, so all air will come through the stock snorkel. With the full lid you will see a 2 horsepower increase. The second lid has an opening in one side for increased air flow and a 4 horsepower increase. The third option is to run with no lid at all for a 6 horsepower increase. No fuel management unit is required with either lid in place. If you remove the lid, you will need a fuel management unit to see a 6 horsepower increase.

Does not come with a filter.

Uses UNI filter NU-4102ST or K&N filter part number RU-2520.
