POLARIS RANGER 900 TUNING TIPS
Terry's Tuning Tips:
ECU: The Polaris 900 Ranger models in stock form are doggy and slow. 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. 2013 and 14' models go from 60hp stock to 78hp after our tune. 2015+ models go from 68hp to 84hp. Speeds of 70+ mph are seen on most machines! Clutching is an absolute must to 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: The stock clutch calibration on all 900 Ranger models is absolutely horrible. It has clunky / jerky take off, and performance characteristics similar to a riding lawnmower. 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. The kit consists of primary weights, spring and detailed instructions. We offer the Elite Shift clutch kits for stock and tuned machines. Our ECU tune/clutch kit packages come with an Elite Shift clutch kit or you can chose to go with our BlackMax adjustable 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 have a 2013-2015 Ranger 900 I suggest installing the Spider Jam nut to prevent the spider from coming loose in extreme conditions. Polaris started using this jam nut in 2016 on the 900 models.
The stock secondary clutch that comes on most of the 900 models is the cheap Rapid Reaction throw away clutch. These clutches are know to fail because of the cheap design and cause bet slippage in extreme use conditions. I recommend installing our HD Team Tied secondary clutch if you want the absolute strongest and best performing secondary clutch available for the 900 Ranger!
Duraclutch Upgrade: If you want unparalleled belt life, and overall clutch durability I would suggest the Duraclutch kit.
