RACEBOX x NST 2023+ Nissan Z & 2016+ Q50 Q60 Upgraded Pulley Kit

The Racebox x NonStopTuning VR30 upgraded pulley kit is designed for customers with a Nissan Z, Infiniti Q50, or Infiniti Q60, looking to swap their plastic OEM Idler & Tensioner pulleys for stronger aluminum pulleys. Superior to other options, Racebox x NST Idler & Tensioner Pulleys include high quality serviceable bearings, are anodized for exceptional durability, and are compatible with the OEM belt. This solves the belt slip/jump issue with the VR30!
