R56 Cryo Connecting Rod Set
N14 / N18 Engines
Internal strength upgrade for engines that are pushed beyond factory limits.
When power goals move past stock output, the connecting rods stop being background components and start becoming critical infrastructure. The SneedSpeed R56 Cryo Connecting Rod Set is engineered for N14 and N18 engines that see increased boost, higher RPM, and sustained load—conditions where OEM rods begin to operate outside their comfort zone.
This is not a cosmetic upgrade. It is a structural one.
Built for High-Load Operation
Factory connecting rods are designed around factory cylinder pressures and duty cycles. As boost, torque, and RPM increase, the margin for error shrinks rapidly. These SneedSpeed rods are cryogenically treated to improve material strength, fatigue resistance, and long-term durability under real performance use.
Cryogenic processing refines the internal grain structure of the metal, reducing internal stress and improving resistance to deformation and crack propagation—exactly what matters in a boosted or high-RPM engine.
Key Engineering Advantages
-
Cryogenically treated rod assemblies
Enhanced strength and fatigue resistance compared to untreated stock rods. -
Improved durability under boost and RPM
Designed to withstand higher cylinder pressures and repeated load cycles. -
Precision machined and balanced
Supports smoother operation and consistent performance across the rev range. -
Direct replacement for N14 and N18 engines
Drop-in fit for R56 MINI Cooper S applications during rebuilds or upgrades.
Recommended Applications
-
Boosted street builds
-
Track and endurance engines
-
High-RPM tuning strategies
-
Engine rebuilds where reliability matters more than reusing stock internals
SneedSpeed Philosophy
Power increases are meaningless if the engine cannot survive them.
Upgrading connecting rods is about removing uncertainty from the bottom end and allowing the rest of the build—turbo, tune, fueling—to operate without being capped by stock limitations. These rods exist to give your engine the internal strength it needs to support the performance you’re asking of it.
