SneedSpeed set the standard for performance MINI timing chain upgrades. Now we bring that same obsession with timing control and durability to the BMW N55 engine.
When you are building a serious BMW N55, timing integrity is not optional.
The N55 makes strong power, but once boost, RPM, heat, and cylinder pressure go up, the timing system matters even more. As the chain wears, timing accuracy starts drifting. Performance gets less consistent. Reliability margin gets smaller. That is where the SneedSpeed BMW N55 Cryo Timing Chain Kit earns its place.
This is not a generic stock replacement timing set. The SneedSpeed kit starts with premium timing components, then goes through deep cryogenic treatment to improve wear resistance, long-term durability, and stability under real engine load. More abuse exposes weak parts fast. Better timing components help keep your engine precise when the demand goes up.
On an N55, timing chain stretch is not just wear. It is lost precision. Once cam timing starts moving around, engine response, consistency, and long-term confidence all take a hit. A stronger timing system helps hold timing control where it belongs and gives your build a better foundation for real performance use.
Whether you are refreshing a worn BMW N55 engine or building a higher-demand street or track setup, this kit is built for owners who know stock parts stop looking impressive the second power levels go up.
Fits BMW N55 applications including:
135i, 235i, 335i, 435i, 535i, 640i, 740i, X3 xDrive35i, X5 xDrive35i, X6 xDrive35i, M2, and other BMW models equipped with the N55 engine.
