901 Pro Tuner kit -Adjustable weight kit for 900 Ace Turbo pDrive clutch (non-clicker type)
75g-84.3g (higher gram range for modified versions)
The 901 Pro Tuner kit is a fully adjustable weight kit for the 900 ACE Turbo with pDrive primary clutch.
Designed as a high quality billet steel flyweight set to help satisfy the demand from performance shops, racers, and those clutch tuners who modify the ECU programming or add extra Horsepower and need extra weight added to the flyweights. The 901 kit is designed to allow the use of more weight.
The flyweight top profile is similar to the stock BRP #873 ramp curve on these models. There are two threaded passages to allow adjustment of mass to the inbound or tip position. The inbound weight or”heel” position uses Dalton’s popular “Quick Adjust” method, that allows you to fine tune the grams without even removing the flyweight from the clutch. There is also a threaded tip weight adjustment that allows you to adjust the “zone” of the grams needed, and the amount of tip weight required for the application.
There are many combinations of added fasteners that will allow fine adjustments of “total grams”, as well as placement locations. Many combinations of less than one gram increments can be done in different configurations of weight placement.
Most 900 Ace Turbo models come with approximately 75g stock weights. The Dalton 900/901 T Series flyweights are designed as a complete drop in assembly. These are the only sets we have designed and offer as proper fitment for the 900 ACE pDrive clutches. The weights are the proper length, width and dimensions to fit properly in the clutch. They have a close tolerance high quality bushing, and there are no additional hardware, clickers, or spacers required. You simply bolt them in like stock weights.
This set is for more for modified vehicles. For stock or lightly modified versions the regular lighter set DPT-900-T would be most commonly used. Be sure to specify proper part number. If you are doing higher HP programming check with your performance shop or provider for gram requirements.
As the name suggests, this Pro Tuner Kit was designed to help satisfy requests from clutch kit companies, pro racers, and performance shops who want to tune their own clutching to suit their own needs and/or performance levels.
