Stock or oversized tires, adjustable kit DUV P8RZ-11 New adjustable clutch kit for the 2011, 2012 RZR and RZR "S" models. Polaris RZR models continue to evolve. 2010 introduced some new clutches and components from the factory, and the 2011,2012 800 cc models have different engine configurations which require slightly different clutch calibration. Adjustable clutch components let you get your clutch/belt shift pattern correct for your specific application. Some of our kits look similar, however they are different and model years and applications are important. Kit comes with adjustable flyweights and a "set -up guide" for most common applications including tire sizes, typical bolt on mods and altitude adjustments. This kit is not for the 900 XP RZR. For more detail on the differences in RZR models see the FAQ |
2010 Polaris RZR (oversized tires), and 2010 RZR "S" model (stock or oversized tires). Adjustable kit. DUV P8RZ-10 A different version of our popular clutch kit for the Polaris RZR models. The 2010 has a different secondary clutch and calibration than earlier year models. This kit has a different set of flyweights and a new set up guide that is specific to this model year. The flyweight design allows for the use of more flyweight mass in a different configuration than the factory clutch calibration, and offers tunability to adjust for case specific applications including tire sizes, elevation , etc. Please note the applications listed for this kit. The regular 2010 RZR (non "s") stock clutching is a good calibration for stock tires.

New! Polaris RZR Turbo flyweights. QPRZ-T Turbocharged RZR Applications. Adjustable from 78-85.5grams This new version of our patented "Quick Adjust" is an agressive curve in higher gram increments for turbo applications. The Quick Adjust means you can add or subtract grams without even removing the flyweights from the clutch. This flyweight type,and the location of mass will often act a few grams heavier than other flyweights with typical 10 series Polaris curvature that you may be comparing to in turbo applications. All turbocharged applications will be very different. Different terrain,boost levels,tire sizes,secondary clutch options and other tuning components make it a tuners game. If this set is within the gram zone you are using, "Quick Adjust" makes it easier to make gram changes on the fly and get your own application dialed in. This is not a clutch kit, but a set of adjustable tuning flyweights for experienced clutch tuners and turbo owners who know what they want to test. |

06 -09 fuel injected models w/EBS. 0- 4000' elevation. DBW500EF A cost-effective kit designed to help restore some of the acceleration lost from installing bigger tires. Some notes on this model: 500 EFI models with engine brake clutches 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, acceleration, 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 mph) with this kit installed.This kit is NOT for use with stock tires at low elevations.
08-11 Carb version with Non EBS clutches. 0-4000' elevation . (Oversized tires only) The Polaris 500 HO in its standard version is one of the best value ATV models in the industry. This is a clutch re-calibration kit to help restore losses in performance form adding bigger tires.This kit improves efficiency and performance. 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 |
2004.5 and up, 0-2000', stock tires only DP700E 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 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)
2002-2004 DBW 700 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. 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. |

(Optional spring-stock tires) DPPS-P/W 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. 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.
2001-05 (Bottom-mid-range for use with stock or oversized tires) DBW 500 Our most popular kit for the 500HO, it is designed to increase belt grip and acceleration, without losing top speed with stock tires. This kit 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.
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. |
Sportsman 500 (with EBS) 1998-2000 DP 500 SP 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. DBT 500 SP 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.
1999-2004 DSC500 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). Sportsman 400 2001-2004, non EBS DP 400 SP Improved belt grip and bottom to mid acceleration without loss of top speed. This kit works well with stock 25" or 26" tires. DBT 400 SP 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").
2005-07 700 EFI only DUV - P7XP 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. |
