Stingray Helix for CFMOTO CVTech clutch ONLY (NOT OmniDrive). Choose your helix, SRM3, SRM2, SRM2-A, or R1.
Why We Recommend This
The helix is the component inside your secondary clutch that controls how and when it shifts out. If you upgrade the primary without addressing the secondary, the two clutches fight each other and you get incomplete shifts and excessive belt heat. The Stingray Helix matches the new primary calibration so the entire drivetrain works as a system.

We have an installation video, this video will cover all units except wet clutch UForce and ZForce 800 units. This video covers the secondary and primary clutch.
Multi Angle SRM3 Helix, Designed to give a huge boost in low and mid range without losing any top end. Slowed upshift helps with larger tires. Faster clutch backshift and faster response on throttle. Billet cut for durability. This helix will make your unit PULL HARD AND FAST. Please install with secondary spring on B2 setting unless otherwise noted by RNG. Please remember to put hardware back on with blue Loctite. This helix will give you the power you need to run big tires, race, work loads when paired with RNG Primary Clutch Kit. This helix was designed to be the best of the best at everything and it WORKS! The way the multi-angle is set up, this helix gives you the absolute best at every angle, slow wheelie-popping torque to slinging mud to racing your friends. This helix is truly the all-around rider helix. There is nothing else like it out there, it simply is the best at what it does.
Multi Angle SRM2 Helix, Designed for machines that do heavy farm work, pull heavy trailers, mud bog that need torque NOT speed, and even rock crawlers. People who like to do slow technical driving, this helix will give you the power you need to run big tires in the DEEP DEEP MUD when paired with RNG Primary Clutch Kit. This helix is NOT a go-fast helix, it is a torque helix. It's not slow depending on the setup, this helix is a Torque MASTER! This helix also helps with high altitude mountain driving.
Multi Angle SRM2-A Helix, Very much the SRM2's big brother. This helix was designed specifically for you guys wanting that SRM2 power but also find yourself at faster-paced speeds. Maybe you hit a little road here and there or you hit some fast-paced trails. Well this helix will surprise you. If you're deep mud riding with big tires, pulling heavy trailers, mud bog, you need that torque NOT speed, and even rock crawlers and people who like to do slow technical driving. This helix will give you the power you need to run big tires in the DEEP DEEP MUD but it will also give you more usable top-end speed. While this helix should not be considered a full-on replacement for the SRM2 (the SRM2 still provides more low-end torque for those sticky situations), when paired with RNG Primary Clutch Kit you will find yourself with all the power you need. This helix also helps with high altitude mountain driving.
RNG R1 Multi Angle Helix, The master at SPEED. RNG designed this helix for the riders that like FAST. Fast-paced trails, street riding, racing your friends or on the track, sand dunes, ice racing, etc. This is the helix you want! The R1 Helix was designed to give you a boost not only on the bottom end but the top end as well, making this the perfect helix for the guys who like to go fast and keep up the pace. There isn't a helix out there quite like this one. Get the low-end torque you need and get the top end you want all in one package. NOTE: This helix is NOT for avid mud riders, NOT for tires over 32 inch.
SRM3 vs R1: The SRM3 Helix is like a 5-speed close ratio transmission, set to keep the engine in the meat of the power at low to mid range speeds with maximum torque. Best for bigger tires, mud, average trails, rock crawling, and you don't care about doing 70+ MPH, 60's is more than enough. The R1 is like a 6-speed close ratio, but 6th is overdrive, designed to reach a higher shift-out point, giving you great acceleration, strong hard-hitting corner-to-corner power on a track (aggressive driving) and reaching the highest speeds possible, closer to 80mph area. Great for open areas where top speeds can be achieved (sand dunes, race tracks, desert ripping). More for ZForces and sport machines, can be used on other models looking for performance AND speed.
Most of the time, clutching is a give/take scenario, you can gain more low end and acceleration but you will give up top speed. If you want top speed, acceleration and slow speed torque is given up. The R1 helix will not have AS much bottom end for slower speed high torque scenarios like 32"+ tires and power-robbing mud, the SRM3 is for that. Think Baja or Motocross more than cruising trails with the family.
Feel free to call us with any questions, we can help you set up a kit specifically for your needs as a rider.
If you want the best in class CFMOTO clutch setup, you're in the right place. Redneck has 25 years experience tuning engines and clutches. Not only that, we teamed up with Bill from Stingray Mods who has 40 years experience with clutching, he brought us these BAD TO THE BONE helix designs.

Awesome customer service
Some questions I had and they gave me the recommendations for smoothing out the CVT. Ordered and installed and the results were amazing. Highly recommend RNG for your clutch issues!

Clutch kit
I put this new clutch kit on my 21 uforce 1000 and man I kid you not. . . its night and day! The jerkiness is gone! It's as smooth as Mr Steven said on his videos. I did get the new belt with it. I'm still breaking that in. Got about 15 more miles and then I'm going to see how that baby really handles. I can already tell it's got more torque. Im a happy camper! Thank you RNG for top of the line clutch kit and belt. You're customer service and shipping time is outstanding!

Installed the SRM3 with the primary kit. Yeah Buddy! I put 30” carnivores on and the tires killed bottom end power. I had to run low range most of the time because it lugged the engine and I’m sure it was cooking the belt. After the clutch upgrade…It runs like it did with the 26” tires!! A++ The primary kit takes off smooooth and it dramatically reduced the violent shock when you first accelerate in reverse! Thank you guys for putting in the R&D to deliver a great product! Highly recommended!!
