This is the strongest clutch kit we sell.It`s a direct swap for dual mass flywheel setups, and works with every M-B 6 speed gearbox. Please note that all our clutch kits fit all manufactured engines from the 80`s up to 2010+. They are made to be used only with 6 speed gearboxes. We made them fit all inline engines like the om601/2/3/5/6/16/17 , om612/648 and the m102/3/4. V-shaped engines like the m111/2/3, the legendary m156/9, m137 and the m275/285 ... And many more that share the same crank bolt pattern. We have our kits in old style Octagon bolt pattern, and new style (after 2004) Cross Bolt pattern. The kit includes: 6,1kg CNC Billet CroMo Lightweight flywheel 260mm ceramic friction disc 260mm reinforced pressureplate Crank Bearing Every necessary bolt for mounting the kit. This kit requires little grinding on the inside of the gearbox bellhousing if you are using a gearbox from an inline engine. Installation requires a starter ring gear from automatic gearbox. PM us for questions about your engine and gearbox. Note : Please do keep in mind that on some uneven idling diesel engines the so called gearbox rattle may appear when the engine is idling due to the lack of a dual mass flywheel.
