From Dirt Trax Magazine Vol. 14 No.1
"Seems like demand for large diameter mud tires is experiencing a resurgence despite this summer's dry conditions.Here's a tip we can pass on from the crew at Dirt Trax TV. If you've been following AJ in the trail tech shop you may have seen him installing a Dalton Pro clutch kit on our Can Am G-2 Outlander 1000 in conjunction with a ji-normous set of Silverback mud skins. The difference in performance with the kit and the tires versus the tires without the kit absolutely convinced us you should not buy one without the other."
Here is a link to the Dirt Trax TV trail tech episode

Stock or oversized tires,Adjustable kit.
Commander 1000 "OPTIONS" clutch kit.
This new clutch kit makes it possible to have one kit that suits a lot of different situations. Instead of having many different clutch kits for different tire sizes, terrain conditions, or to help compensate for high elevation power losses, this new kit covers a broad range of tuning challenges.You can tune for better belt grip and improved performance by using different combinations in the kit. A new set of adjustable flyweight lever arms were built for this application. There is a " set- up guide" included to optimize the CVT calibration for most common situations, and you even have a choice of engagement rpm for your preferred riding situations. Having options and tunability means you still have the correct kit if you change tires, do modifications, etc.
Also included in the instructions is a "General Overview of Model and CVT Tuning Guide" that may help clarify the way the system operates, the tuning components, and some basic clutch tuning for those unfamiliar.

06 & up for stock or oversized tires - Altitude adjustable.
Improved bottom to mid range acceleration without sacrificing top speed. A new flyweight with a new curvature was designed specifically for this 800cc Outlander model. These new flyweights can be set up for different applications. You can set up this system for: improved acceleration with stock tires re-calibration to help recover losses from oversized tires, or to help control up shift at higher elevations. Baseline set up guide included for most common applications.
Frequently asked question: Is there a different or better drive belt I should use on this model ?
Although in some instances of snowmobile racing, etc., we will recommend a different particular belt compound or brand for certain specific applications,our testing and race programs have proven very distinctly that the factory belt is superior for this application.
All Renegade 800 versions. Stock or oversized tires.
The 800 Renegade is not only a lighter weight vehicle than the Outlander, it also has smaller stock tires and a different factory clutch calibration. The 800R kit for this model comes with the same base flyweights as the regular Outlander kit, but has different rivets, calibrations, and set up instructions for some of the tire sizes (25" and 26") tire sizes. To use the DBO 800 kit on a Renegade with Stock Tires( 25"), order the optional rivets part #DFRL-Y.
DFR Series Flyweight Rivets For information on available extra, or optional mass rivets for use in ATV applications, see the chart on components.
2006-2012 800 Outlander / Renegade 4 X 4 - For 28" and larger competition mud tires ( adjustable kit.), also Outlander XMR version.

The 500 Can /Am is calibrated quite well for stock tires at low elevation. This clutch kit was developed to help recover losses incurred from installing oversized tires on the Can/Am 500. This clutch re-calibration is a great improvement in acceleration and help with back shifting to proper ratio when under load conditions. Better belt grip for oversized tires. Improvement in throttle response brings performance back to acceptable levels after the addition of the heavier tires. This kit also works well to re calibrate the shift pattern for higher elevations ,even with stock tires. The new "baby V-twin" comes from factory with flyweights that are well suited to its application ,and re-calibrations are accomplished with the use of new springs. An optional engagement spacer for use with the stock primary spring ,and/or the provided primary spring depending on the application and tire sizes used ,and a new secondary spring that was developed specifically for this model. The use of this kit does not hurt top speed when used as instructed for the proper application.

Optional Dalton Secondary Clutch Spring- Can Am Outlander / Renegade 1000, 29.5" + Tires.
This optional secondary spring is designed for use with the Dalton DBO 1000 R clutch kit for the Outlander/Renegade 1000 cc Can Am ATV models, when used with extreme mud tires of 29.5" and larger. This spring is for the BIG mud applications. There are only a few exceptions, such as 28" heavy mud tires AND most often carrying heavy load or passengers.
The DBO1000 R clutch kit includes adjustable flyweights. When using this optional secondary spring, follow the "flyweight set up guide" of your clutch kit instruction manual for the tires and applications.
This spring a torsion/compression spring and is specific to the models described. This spring is for use with Extreme mud tires in 29.5 and larger. Normally, for smaller tires and applications, the best set up is to use the stock secondary spring that came on your 1000 cc model.
FAQ : "I'm a quite heavy trail rider and do some mud with 27-28" tires, and I plow snow in winter. I like the best I can get, and more parts is usually better ...so should I add this secondary spring ?"
ANSWER : No. The regular DBO 1000R clutch kit and the stock secondary spring, set up as the instructions say, is more efficient and the best for your application. Our kits and components have descriptions based on our test results.

This new clutch recalibration for the CAN-AM 650 Outlander 4x4 offers flexible tuning options for stock or oversized tires and high elevations. Improved acceleration, throttle response and backshifting with no loss of top speed when set up properly for your application.This kit uses a different adjustable base weight than the 800 cc kits.
Notes: The Green/Yellow primary spring supplied is the most popular, however, other options are available, see below. If using Extreme Mud competition tires 28" and larger use addition of Yellow /Black secondary spring (see info on this page), and often more flyweight mass is added. Contact us for more tech info .

DPPS-Y/BL can be used as a low engagement option with the DBO650, DBO800, DBO800R, DBO800M clutch kits.
Yellow/Red primary spring part
This primary spring was designed for the competittion mud racers in 650/800cc applications with a higher engagement than the green/yellow that comes in the DBO800 kit and still has the required load rating to work with the adjustable flyweights in the DBO800 / DBO650 kits
Suggested list price
$41 CAD / $41 USD
Yellow/Black secondary spring
For most applications the stock secondary spring on the 800's is preferable,but when using 28 and larger competittion mud tires this new optional secondary spring keeps low belt/clutch ratios better for the mud pits.
