STILLEN 2003-2006 Nissan 350Z [Z33] / 2003-2008 Infiniti FX35, G35 / 2006 M35 Standard Pulley Belt Set - 400337B

The STILLEN Standard Pulley Belt Set is designed for vehicles running either STILLEN standard crank pulleys or factory OEM pulleys. This belt set provides the correct belt length and tension required to maintain proper accessory operation and long-term reliability.

Unlike underdrive pulley applications, standard-diameter pulleys retain factory accessory drive ratios. This belt set is engineered to match those specifications precisely, eliminating issues related to improper belt fitment, slippage, or premature wear. It is an ideal replacement when installing STILLEN standard pulleys or refreshing worn factory belts.

This belt set offers a direct-fit solution for multiple Nissan and Infiniti VQ-powered platforms and is suitable for daily-driven vehicles requiring dependable performance and OEM-level compatibility.
