It's a complete set designed specifically for the S63B44B, N63B44B, and N63B44D 4.4L V8 twin-turbo engines found in a ton of BMW models. We're talking 550i, 650i, 750Li, Alpina B7, M5, M6, X5, X6, and more from around 2012 to 2020—check the full list to make sure it fits your exact car and year. The kit includes everything you need: two timing chains with guide rails, two fixed rails, two upper guide rails, two tensioners, a crankshaft gear, an oil pump chain, and an oil pump gear.
