Optimum CVT clutch calibration for the Polaris Sportsman 850 XP 4 x 4
One clutch kit that can be set up for different terrain and tires sizes/elevation means accurate clutch tuning for your situation. Improved acceleration without losing top speed.Kit includes optional engagement springs so you can set it up for your preference and riding style.
This kit includes Dalton’s patented "Quick Adjust" flyweight system that allows you to add or subtract weight from the flyweights without even removing the flyweights from the drive clutch. Instead of using generic flyweights or designs from OEM snowmobiles or regular ATV models ,extensive testing lead to development of a new custom base flyweight specific to this model. The new "Quick Adjust" SP850 flyweight in this kit has a different curvature ,and location of mass which allows superior belt grip and RPM control .
Ultimate RPM control(can be easily adjusted for modifications)
Stock tires or oversized
Altitude adjustable
New custom SP 850 specific flyweight profile
Set up manual includes set up instructions for above applications

Polaris Sportsman 500 EFI
06 and up fuel injected models w/EBS 0- 3000' Oversized tires only
DBW500EF Suggested list price
$237 CAD / $212 USD
A cost-effective kit designed to help restore some of the acceleration lost from installing bigger tires.
Some notes on this model:
This new 500 fuel injected model is indeed somewhat different than previous 500 HO models. Aside from having fuel injection, it also uses a new primary drive clutch that starts off in a lower ratio, and uses a different belt compound. Testing showed that when using stock tires, the clutch calibration from the factory was satisfactory and no adjustment was necessary. Oversized tires, as usual, did show a significant loss of performance, speed, and acceleration. This kit will help bring your bike back to life after installing those bigger, heavier tires, and also improve belt grip and throttle response. Top speed on this model is slower with big tires than with stock tires, and it will remain the same (within 1-2 mph) with this kit installed. This kit is NOT for use with stock tires at low elevations.
Polaris Sportsman 800 EFI 2006
Stock Tires
If you intend to stay with stock tires on the new 800 EFI 4x4, we have found it is very well calibrated in stock form for most conditions. If our testing does not show significant gains in belt grip, acceleration or speed / backshifting without negative trade offs somewhere else in the powerband, we prefer to simply use the stock calibration. There is nothing wrong with the fact that it has good clutch calibration from the factory. This model performs very well considering its total dry weight and stock tire size / configuration. Sometimes clutch set ups that "feel" better are simply NOT better when properly field tested.
The stock 800 EFI comes with 26" tires. If you choose to switch to heavier, more aggressive 26" w/10" wide fronts and most 27" tires, the 800 will perform better by simply adding our Orange/ blue (part # DPPS-O/BL) primary spring. For all 28" & up tires use complete kit (Part# DP 800EXT) - We simply prefer to not sell you more than what you need.
Extreme mud tires. This clutch recalibration kit is designed for the serious mud runners and those using larger aggressive mud tires, (28" and up). For use on stock machine - 0-3000'. May cause slight loss of top speed
Polaris Sportsman 700 EFI
2004.5 and up, 0-2000', stock tires only
DP700E Suggested list price
$205 CAD / $183 USD
Our initial testing showed the EFI 700 to work quite well in stock form. It did, however, have room for improvement.We designed a new primary spring and a custom-ground set of billet flyweights for this application, achieving much better belt grip in high range, less hitting of the rev limiter in loose conditions and more consistent RPM control with no loss of top speed. This kit engages right off idle just like the stock clutching and although drag racing results only show a slight advantage with this kit installed, (approx. one bike length in 400 ft.) high range is much more effective at lower speeds.
DP700 EBT Big wheel kit
Suggested list price
$246 CAD / $219 USD
Proper clutch re-calibration is critical when oversized tires are added on the EFI 700. This kit drastically improves low speed belt grip and throttle response to bring your big Sportsman back to life. To upgrade the stock tires kit to the Big Tire Kit, the following parts can be purchased individually. DPSS -B (Black secondary clutch spring), DPS-SW (Spacer washer)
Polaris Sportsman 700
2002-2004
DBW 700 Suggested list price
$237 CAD / $212 USD
Our most popular for the SP 700 was designed around the same objective as our successful DBW 500 kit. Great all around trail performance, with an emphasis on bottom and midrange acceleraton and improved belt grip. This kit works well to restore power loss from bigger tires, and is a favorite even with stock tires. (This kit often results in loss of 1-2 mph on top speed when used with stock tires.) -includes billet DaltonPro flyweights, new primary spring, new secondary spring. Designed for use with stock helix, stock or oversized tires.
DP700A Suggested list price
$335 CAD / $299 USD
More aggressive acceleration for high performance riders. Includes a set of billet steel DaltonPro flyweights, a different primary spring, and a billet helix. This kit was designed for use with the gearing and rotational mass related to stock tires, and in fact can benefit from using lighter weight wheels and tires (not larger than stock size). Not for use with oversized tires.
Sportsman 600
(Optional spring-stock tires)
DPPS-P/W Suggested list price
$33.50 CAD / $29.95 USD
2003-04 Our testing of the new SP600 showed that
this quad was very well calibrated "out of
the crate" in stock form. Our new Dalton
plain/white primary spring has only slightly
higher initial load, but slightly lower finish load than the stock
primary spring. Use of the plain/white primary spring keeps the
engine in a better part of its power curve all the way through the
shift pattern. Better bottom/mid acceleration with 1 mph gain on
top end resulted. For stock tire application.
DBW600
Suggested list price
$73 CAD / $65.50 USD
Oversized Tires
With stock tires, our testing has shown this model to be quite
well calibrated in stock form. With the
addition of oversize mud tires, our heavier
Dalton EBS black secondary spring was
used in conjunction with our plain/white
primary spring.We now package this popular
combination in kit form, complete with
instructions. The result is better belt grip
and acceleration, along with much better throttle response and
backshifting. When used with stock tires this kit may cause a
slight loss of top speed (1-2 mph).Works well with high altitude
applications.

More aggressive acceleration
for high performance riders.
Includes a set of billet steel
DaltonPro flyweights, a different
primary spring, and a billet
helix. Designed for use with
the gearing and rotational mass
related to stock tires, and in
fact can benefit from using
lighter weight wheels and tires
(not larger than stock size).
Not for use with oversized tires.
Improved belt grip and bottom to mid acceleration without loss of
top speed. This kit works well with stock 25" or 26" tires. This kit is
NOT for use with larger than 26" tires.
Improved belt grip and bottom to mid acceleration.
This kit was designed to get big tires turning in heavy mud applications
and correct the shift ratio for larger tires.
Polaris 500 Scrambler
1999-2004
DSC500 Suggested list price
$359 CAD / $321 USD
Includes our billet flyweights, a
new primary spring, a new secondary
spring, and a custom billet
helix. Improved belt-grip, throttle
response and bottom to mid
acceleration without loss of top
speed. Designed for stock tires (0-2000 ft. altitude).
Improved belt grip and bottom to mid acceleration.
This kit was designed for extreme mud applications and to correct
the shift pattern for larger, more aggressive tires ( 27" or 28").
The Ranger XP often exhibits over rev during
its shift phase on typical hard packed
trail surfaces at times even bumping the rev
limiter prematurely during acceleration.
This kit includes a new primary spring and a set of flyweights that
were ground specifically for this application. Better belt squeeze
and quicker upshift / acceleration in mid range.- For stock tires
sizes only.
