Like the 8″, the 9″ billet system can be customised to suit many larger engine and gearbox combination, utilizing a custom billet steel or aluminium flywheel. Being available in single, twin and triple plate configurations, the 8” unit can be tailored to your exact needs with a large range of friction materials, compounds, button arrangements, clamp ratings from 1500 – 4000lbs and so on. Made from the highest grade materials which are Australia, japan or USA sourced.
Supplied as a clutch and flywheel assembly the Direct Clutch Services 9″ billet system has proven to be a durable unit, in all rigorous applications and is usually an economical unit to rebuild when required.
All of the Direct Clutch Services billet single twin and triple plate units can be made to a specific target (assembly) weight. We are happy to advise / assist with this , but generallly speaking , we suggest light weight for any constant high RPM application ie circuit , speedway , marine applications. We generally suggest the heavier the better for any street , drift , drag , and all 4×4. In recent times we have seen success in drag racing with the heavier (clutch and flywheel) assembly options. We have also seen gains in drifting with heavier flwheels being used. This generally sees the ability to turn the tyres at lower rpm clutch kicks as the engine is less likely to stall. We also see the heavier flywheel acting as a large(r) heat sink and allowing more heat to be absorbed into the flywheel before, thus intiially taking heat away from the clutch. We have common assembly weights on file for most applications.
