Together with the option of adding our Capture Plate for ultimate security.\u003c\/p\u003e\u003cp\u003eThe centrepiece of the MMR kit is the UK made CNC-machined one-piece crank hub, created from billet EN36 steel that's heat-treated with a 0.75mm case hardening, making it incredibly strong and durable. Included are four aerospace precision machined dowels that mechanically lock the hub to end of the crank itself, plus a brand new OE bolt.\u003c\/p\u003e\u003cp\u003eInstallation of these dowels is certainly not a DIY job. But, to make the job easier for the professionals, ensuring that the required crank modifications are made safely and accurately, the MMR kit also includes a full installation jig that includes a bolt-on drilling guide, a location bolt for this guide, plus an HSS rolled high-speed drill bit.\u003c\/p\u003e\u003cp\u003eTogether, the single-piece design combined with the four-pin location ensures that there is simply no way that the friction plates can ever slip. With the new OE crank bolt tightened appropriately, this delivers a transformational improvement in reliability and peace of mind versus the OE version.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eFeel free to contact us at info@mlperformance.co.uk should you wish to double check!\u003c\/p\u003e \u003cp\u003e \u003c\/p\u003e \u003ch4\u003eCompatibility Check\u003c\/h4\u003e\u003cp\u003eTo ensure the part(s) you have ordered fits your vehicle, we run a compatibility check prior to dispatch.
