Main & Rod Bearing Kit

Aston Martin · AMG M177 / M178

Precision bearing kit for high-accuracy rebuilds and performance upgrades on Aston Martin powertrains using the Mercedes-AMG 4.0 L twin-turbo V8 family (M177 wet-sump / M178 dry-sump). Engineered for sustained thermal, torsional and boost loads.

Kit contents

  • Main bearings (upper & lower) for all five crank journals, grade-matched for precise crank-to-block clearances.
  • Connecting-rod bearings (upper & lower) for all eight rods.
  • Thrust washers to control axial crank movement.
  • Color coding / tolerance matching to pair shells to crank and block, minimizing selection error.

Specifications

  • Standard (OEM-grade): faithful restorations and stock-like rebuilds.
  • Elite (performance): reinforced overlays for high-load fatigue resistance.
  • Optional surface treatments and micro-finish optimization.
  • Pre-selected balanced sets and targeted clearances.
  • Configured for elevated boost/torque and robust transient load handling (incl. hybrid assist).
SKU SB53-SE6600-AA

Fitment: verify by VIN and engine plate. Measure journals and saddles; select shell grades accordingly. Follow OEM torque/angle procedures and oil spec for break-in.
