2009-2024 Nissan GT-R

Built for performance and durability, the ACL Race Series 1M2505H‑STD‑2 Main Bearing Set is a high‑quality replacement designed to support upgraded Nissan GT‑R engines. Main bearings play a critical role in the bottom end by supporting the crankshaft and maintaining optimal oil film under demanding conditions. Upgrading to ACL’s Race Series bearings provides improved strength and reliability over factory shells — especially in boosted, high‑RPM, or motorsport applications.


Precision Engineered for Performance

  • Application: Nissan GT‑R R35 with VR38DETT engine (oversized +0.20mm)

  • Race Series Quality: Tri‑metal construction engineered for high horsepower, extended use, and durability

  • Material: High‑strength overlay and hardened steel backing for fatigue resistance

  • Grooved Design: Enhances oil flow and load distribution for crankshaft protection

  • Precise Tolerances: Consistent wall thickness and oil clearance for reliable performance

ACL Race Series bearings are designed to handle greater loads and repeated stress, making them ideal for performance engines where stock bearings may fall short.


Why Upgrade Your Main Bearings

Upgrading to ACL Race Series main bearings helps:

  • Improve reliability under increased boost and RPM

  • Maintain stable crank support under high load conditions

  • Reduce risk of bearing fatigue and failure

  • Provide long‑term performance consistency for street, track, and race use
