Dont Let This Part Destroy Your Coyote Engine!! The Problem And The Fix >>>>

MMR has had a overwhelming # of calls from engine builders and customers across the country with broken/failed lower crankshaft sprockets. It seems the majority have been those with upgraded camshafts but many have also been stock applications. We even received a call from a MMR dealer (BBR) who had even broke 2 on the same engine. When this part breaks catastrophic failure is certain (bent valves, damaged pistons,cylinder heads etc). MMR went to work quickly on a solution and are now selling the MMR Billet Steel gear. This gear replaces the factory powdered metal gear directly with no other changes, the MMR gears are manufactured from billet 9310 heat treated material and precision made in the US by MMR. If you are building aftermarket engine, have a Ford Racing Aluminator, or rebuilding a coyote engine you need one of these!!! Retail on the Billet steel gears is $239.

Order here: 11-14 MMR 5.0 Mustang Coyote Billet crankshaft gear / sprocket [467891] - $239.99 : Modular Motorsports, Home of the Worlds Fastest Modular Engines
