Clutching

Manufactures have a really tough job when deciding on the stock clutching system and its calibrations for the Polaris Ranger Mid-Size. Someone who buys a Mid-Size might be a farmer or rancher who will use the machine for plowing snow or hauling bales of hay. Someone else who buys a Mid-Size might use it to run steep trails or power through the mud. Because of this, stock Polaris Ranger clutches have to perform adequately across a variety of riding styles and conditions and therefore are not optimized for any particular riding style or condition. The clutching on a Polaris Ranger Mid-Size -- and all UTVs for that matter -- does not change the machine’s gearing. Rather, it controls the rate of upshift and backshift in the clutches. Simplistically speaking, the clutching chooses the right time to shift your 5-speed transmission as it speeds up and down. Shifting too fast or too slow to the next gear is not optimal, and will reduce performance, acceleration, etc. If the stock clutching on your Mid-Size does what you need it to as is and you are not having any issues with belt life or clutches, we’d suggest just leaving it be. However, if you’ve made a lot of changes to your machine -- such as adding larger, more aggressive, tires -- or use it for one single purpose, swapping out the clutch or getting a computer to reflash can provide significant performance boosts.

If your clutching system is defunct and not functioning properly, you may not need to replace the entire thing. In many cases, simple weight adjustments and other calibrations can fix the issue. In other cases, fixing or replacing a few of the component parts of the clutch can do the trick. For example, a friend of the site came to us with his 2016 Mid-Size ETX wanting quicker engagement less shudder. Because the weights and springs are what calibrate the clutching to run at a certain rpm and determine the shift ratios and speed in the clutches, we suggested a heavier primary spring to raise the engagement rpm. If the weights in the clutch are too heavy compared to the spring, they will pull the rpm way down and make it boggy, unresponsive, and slower. Little things like this can be extremely frustrating if you don’t know what you’re doing. So if you need some assistance with the clutch in your Polaris Ranger Mid-Size, drop us a line and we will get everything straightened out in no time.
