Product Details

The Vortex 775ZR-37 is a 37-tooth, 525-pitch aluminum rear sprocket engineered for performance street and track riders who demand precision drivetrain components. Built to exacting tolerances, this sprocket delivers reliable power transfer and a noticeable reduction in rotational mass compared to OEM steel units.

Key Features:

  • 37 teeth for optimized final drive ratio and gearing flexibility
  • 525 pitch chain compatibility
  • Lightweight aluminum construction reduces unsprung and rotational weight for improved throttle response
  • Precision CNC-machined to ensure concentricity and smooth chain engagement
  • Anodized finish for corrosion resistance and lasting appearance
  • Direct OEM-style bolt pattern for straightforward installation — no modifications required

Vortex Racing sprockets are manufactured from aerospace-grade aluminum to precise tolerances, resulting in a sprocket that is stronger, quieter, and more concentric than many competing brands. Whether you are fine-tuning your gear ratio for quicker acceleration or replacing worn OEM hardware, the 775ZR-37 is a proven upgrade for performance-minded riders.

I received the bar and it looks to be very high-quality. However, this bar says it fits a 2003 through 2013 dodge ram 25 and 3500 series trucks. However, from 2003 to 2007-1/2. This truck comes with 1/2' (14mm) bolts. This bar only comes with the 14 mm and the upgraded 5/8' Hardware for the top joint. The lower joint connecting to the Axle only has the 5/8 hole and does not come with a reducing kit nor does it come with an upgraded 5/8' bolt, which would at least allow you to drill out the lower Mounting holes to mount this bar. As a result, you cannot use the original bolt and you have to go to Supply store to find the correct size bolt to allow you to mount this track bar. Highly inconvenient for the customer, especially when there is no mention of this in the description for the part. At the bare minimum, this track bar should've came with the second 5/8' bolt With the kit.

Very Easy to use and find what I needed!
