• Installation Notes:
  • Requires precise installation and clearance checks, especially for high-lift camshafts.
  • Ensure valve spring specifications prevent binding during operation to avoid engine damage.
  • Clearances between the camshaft and the cylinder head should be checked before installation, particularly on high-lift applications.
• Additional Parts Required: Solid valve lifters (RA307A-NS05A) and necessary shims, guides, and valve springs depending on the engine configuration.

Design and Usage:

The RA301A-NS05L camshaft is designed to improve the performance of your RB26DETT engine by offering increased lift and extended duration for both the intake and exhaust valves. These modifications allow for improved airflow and higher RPM capabilities, making it ideal for applications where maximum engine performance is required. However, it is crucial to ensure the proper installation and clearance during setup to prevent damage to the engine components.
