Product Details

The Vortex CK5142 is a GFRA (Go Fast) 520 conversion chain and sprocket kit designed to deliver quicker acceleration by dropping one tooth on the front sprocket from OEM gearing. This ready-to-install kit requires no chain cutting and includes a hardcoat aluminum rear sprocket, a steel front sprocket, and a Japan-manufactured Vortex Performance Links 520RV3 chain.

Gearing Specifications:

  • OE Gearing: 16 front / 43 rear
  • Kit Gearing: 15 front / 43 rear (one tooth down in front, stock rear)
  • Chain Type & Length: 520RV3 — 108 links

Chain Features:

  • Made in Japan to premium quality standards
  • SV3 Series dual-pocket sealing system — delivers up to 7 times longer wear life versus standard O-ring chains
  • Rivet-type master link included; clip-type master links available separately
  • No chain cutting required — pre-sized for direct installation

Sprocket Features:

  • Rear sprocket: Hardcoat anodized aluminum for reduced rotating mass and improved durability
  • Front sprocket: Induction-hardened steel construction
  • 520 pitch — lighter and narrower than most OEM drive setups

The 520 conversion reduces overall drivetrain weight compared to larger-pitch OEM setups, freeing up horsepower and reducing gyroscopic forces. Compare OE gearing to Vortex kit gearing to verify final drive ratio changes before installation.
