Product Details

The Vortex 642AZGV4-42 is a 42-tooth aluminum rear sprocket featuring a striking gold anodized finish. Engineered for riders who demand both performance and style, this sprocket is part of Vortex Racing's renowned VTX aluminum sprocket lineup — a direct upgrade over heavy OEM steel units.

Key Features:

  • 42-Tooth, 520-Pitch: Designed for 520-pitch chain applications, delivering optimized gearing for street and track use
  • 7075-T6 Billet Aluminum Construction: Aerospace-grade alloy provides an exceptional strength-to-weight ratio for reduced rotating mass
  • Gold Anodized Finish: Applied before the sprocket teeth are cut, resulting in Vortex's iconic two-tone machined look while providing corrosion resistance
  • 100% CNC Machined in the USA: Precision manufacturing ensures perfect concentricity for smooth, efficient power transfer
  • Patented Tooth Design: Vortex's unique tooth geometry reduces friction, extends sprocket life, and improves chain engagement
  • Lightweight Design: Significantly lighter than stock steel sprockets, reducing rotating mass for improved throttle response and acceleration

Vortex Racing sprockets are trusted by professional race teams worldwide and are built to the tightest tolerances in the industry. The 642AZGV4-42 is a bolt-on performance upgrade that delivers real, measurable improvements in acceleration, deceleration, and overall drivetrain efficiency.

The turbo (s475sx-e) has been my best purchase this year. The order was placed at the end of the workday and Thmotorsports shipped it the very next morning, also the box arrived in magnificent condition, the turbo was picture perfect without a blemish. Thmotorsports was the most affordable out of all ten sites that were considered, with top notch shipping. I have to say Thmotorsports was the best choice for my genuine part.

As always great experience. I have ordered from this place in the past and have never had a bad experience. Much appreciation to this company and the people who work there. Thanks again.

Your online system would not allow me to put my Alaska address for billing, even though the order was to be shipped to Texas. I sent repeated emails requesting a phone call and no one would call me or provide me a number to call.

Fast easy service just what I look for

Easy so far
