DaltonPro Clutch Kits for Automatic ATVs
Polaris Sportsman 700 EFI
 |
DP700 E 2004.5 and up 0-2000', stock tires only | $199.00 |
| Our initial testing showed the EFI 700 to work quite well in stock form. It did, however, have room forimprovement. We designed a new primary spring and custom-ground set of billit flyweights for this application,achieving much better belt grip in high rang, less hitting of the rev limiter in loose conditions, and moreconsistent RPM control with no loss of top speed. This kit engages right off idle just like the stock clutchingand 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 | $239.00 |
|
Proper clutch re-calibration is critical when oversized tires are added on the EFI 700. This kitdreastically improves low speed belt grip and throttle response to bring your big Sportsman backto life. To upgrade the stock tires kit to the Big Tire Kit, the following parts can be purchased individually. |

Polaris Sportsman 700
 |
DBW 700 02-04 | $230.00 |
| Our most popular for the SP 700 was designed around the same objective of our successful DBW 500 kit. Great all around trail performance, with an emphasis on bottom and mid-range acceleration 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 to 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 | $325.00 |
| 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 over-sized tires. | ||
Polaris Sportsman 500EFI - '06 & up fuel injected models w/EBS 0-3000' Oversized tires only
 |
DBW 500EF | $230.00 |
|
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 500HO 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 600
 |
DPPS-P/W | $32.50 |
| 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 order part# DPPS-P/W. | ||
 |
DBW 600 - Polaris SP 600 ('03-'04, oversides tires) | $71.00 |
| With stock tires, out 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 will cause a slight loss of top speed (1 2 mph).Works well with high altitude applications. | ||
Sportsman 500 HO (01-05)
|
|
DBW 500 | $230.00 |
| (Bottom-mid-range for use with stock or oversized tires) Our most popular kit for the 500HO, it is designed to increase belt grip and acceleration, without losing top speed with stock tires. This kits also works well to restore lost power resulting from bigger tires. Engagement is only slightly higher than stock. Includes billet steel DaltonPro flyweights, new primary spring, new secondary spring. Designed for use with the stock helix, and with stock or oversized tires. | ||
|
|
DP 500A | $325.00 |
| More aggressive acceleration for high performance riders. Includes a set of billet steel DaltonPro flyweights, a different primary spring, and a billet helix.

Kawasaki, Suzuki, Arctic Cat - V Twin Models
The powerful Kawasaki V-twin engin format is now used on more ATV models. The proven Prairie 650, the larger displacement new Prairie 700 4x4 and Suzuki Twin Peaks, the KFX 700 V-Force sport ATV and the new Arctic Cat 650 4x4.
Similar engine design has made clutching somewhat similar, however, things like dry weight, tire size and weight, transmission calibration and, in the case of the V-Force, different ignition and valve timing, have created the slightly different required shift characteristics.
Our field testing has resulted in the following options:
Kawasaki 650/700, Prairie 4x4, Suzuki Twin Peaks 4x4 (stock, 0-2000' elevation)
 |
DK650/700S | $71.00 |
