Enhance the bottom‑end strength and reliability of your Nissan GT‑R with the ACL Race Series 1M2505H‑STD‑3 Main Bearing Set. Designed for performance and extreme duty engines, these high‑quality tri‑metal bearings offer improved durability and load‑carrying ability over factory bearings — critical for high‑boost, high‑RPM, and track applications.

Whether you’re building a boosted street machine or a race‑ready powerhouse, ACL Race Series bearings provide a strong foundation to support increased power and sustained engine demand.
