ACE 900

Scroll Down For Products

ECU: The Polaris 900 Ace models in stock form are far from their maximum potential. The factory ECU program is designed to restrict power and speed. Our ECU tune will eliminate those power and speed limiters along with many other awesome features. Speeds of 75+ mph are seen on most machines! The Elite Shift clutch kit we offer will make this ECU tune deliver everything it has to offer. Our ECU tune/clutch kit package is the biggest bang for your buck performance gain available!!!

Clutch: Our Elite Shift clutch kit offers very smooth take off and is designed to allow the engine to run at the proper RPM where it performs the best with our ECU tune. The kit consists of primary weights, spring and detailed instructions. We only offer an Elite Shift clutch kit for tuned machines. Our ECU tune/clutch kit packages come with an Elite Shift clutch kit. If you are running larger than 29" tires you will need to purchase the Mudder Secondary Spring which will squeeze the drive belt harder preventing belt slippage. 
If you are someone that likes to test/tune and play with different setups then I recommend purchasing a set of our BlackMax adjustable clutch weights. The BlackMax adjustable clutch weights allow you to add or remove weight in order to raise or lower the engine operating rpm. The adjustable clutch weights are popular for large tire builds, competition use, and high elevation use. We also offer the BlackMax adjustable weights in a kit that includes the weights, primary spring and an option secondary spring for larger than 29" tires. It is also an option to chose the BlackMax adjustable kit in our ECU tuning packages. 

If you would like to ditch the cheap rapid reaction secondary clutch then look into our HD Team Tied clutch.  

Belt: The stock Polaris belt is weak and cannot handle any type of stress. I have found the G-Boost BadAss 1148 belt to be the absolute best performing and longest lasting belt on the market. I highly recommend installing one!!! ​
