DEFENDER HD10/MAX 20-22 CLUTCH KIT

OEM #DB HD10-20

Better belt grip and improved performance for oversized tires. This kit is primarily developed to help recover power losses from adding oversized tires to the Defender HD10. Provides a significant improvement in performance and belt efficiency for the applications listed.

Most stock models** with 27” stock tires do not necessarily need a clutch kit, however, larger or heavier tires can be a serious drag on performance. The custom, adjustable flyweight lever arms were developed specifically for this application and work in conjunction with the rest of the components in this kit. They have a slightly different curvature and location of mass to allow the arm to squeeze the belt harder on initial acceleration. A better clutch calibration for controlling “rate of shift of the belt” with larger tires. Includes a custom ground billet helix ramp that controls the shift specifically for this application. The kit can easily be set up for efficiency with different sized tires/applications. Helps restore RPM to the proper zone. Designed around the use of the most popular 28-32” tires. Tires larger than 32 should be looking at gear reduction for better efficiency. The instruction manual tells you exactly how to set up for different tire sizes and situations.

Seasonal use of Stock tires and winter Track systems – For most applications the stock clutching is ok for this vehicle with stock tires. This kit is designed for use as a re-calibration for oversized tires. Some heavily loaded vehicles for work or heavy large cab models that carry more load/equipment can also benefit from the use of this kit, set up like the instructions shown for 28” tires even though they have stock tires.

Some users also only use oversized tires part of the year. There are some notes in the instructions on how to set the adjustable flyweights for seasonal use of stock tires. Track systems are also a seasonal item, and are geared down internally, so they get set up similar to stock tires. If you have stock tires and tracks, you can leave it with stock clutching, If you use oversized tires most of the year, and use track system in winter season, there are settings in the kit for that application.

**Note- also used even with stock 27” tires on “Limited” model, as it has a much heavier full cab, and the drag from A/C pump, etc. is significant.
