- AA's custom cut helix for the 2016-2020 RZR XP Turbo & Turbo S, 2018-Up RS1
- Does not fit 2021-up turbo models or any year Pro XP
- Purchase this if you already have our clutch kit, or if you have another brand clutch kit. Keep in mind clutch weight adjustments will be made depending on helix choice. It is best to use only our helixes with our clutch kit and proper setup guideline for that helix.
- 2016 models will require upgrading to the 2017 helix buttons (Purchase these HERE)
- Our performance custom cut helix which will give you better power to the wheels on 2017-Up models because of the steeper angle. On 2016 models you will see quicker RPM climb into peak power, and better belt life. All models will see a more consistent RPM sweep. Factory helixes start off steep, then go shallower on the top end. For turbo machines, this is completely backwards. We run a straight angle as changing the load on a heavy machine in the middle of a shift can cause some issues. Basically, 2016 helixes were too steep and therefor had belt issues, 2017+ helixes went MUCH shallower and the performance to the wheels suffers. We found just the right angle to make everything happy with great belt life and great performance.
- This will come with our S3 clutch setup instructions. If using another brand clutch kit, drop roughly 3 grams of primary clutch weight on a 2017-Up model, and add roughly 3 grams on a 2016 model.

Nice flip flops
Size: 7, Color: Grey
Nice looking flip flops. They feel good and well made, but I've only worn them for a few hours. The material that goes over the feet is almost too stretchy. I hope they don't stretch out more. I have wide feet and these fit great, true to size. I like the grey color.

Love the material!
Size: Large, Color: Black
Very soft and beautiful material. The size was perfect. It works well for layering and can also be dressed up. It is not clingy at all. The quality is great.

Worked well for my needs!
Size: X-Large, Color: Black
Nice thick material. I think these could be workout shirts or regular day attire. Soft, wash well, nice stretch, and arm pit gaps aren’t a so wide they look silly or sloppy. Good value for the money. True to size as well.

Great Fit & Great Price
Size: 3X-Large, Color: White
The material is very nice and soft but not clingy. It’s light weight but not see through in both white and peach. This tank fits true to size and has no gaps under the arm like some other tanks I’ve tried. It’s a perfect layering piece under shirts and sweaters. Very affordable and well made. I’m a plus size lady who is happy with the fit.
