Vortex CK6285 GFRA GoFast Aluminum 520 Chain & Sprocket Kit

The Vortex CK6285 is a GFRA GoFast Aluminum 520 Chain and Sprocket Kit designed to deliver a quick-acceleration gearing upgrade over the factory setup. This complete drive kit drops one tooth in the front while retaining a stock-count aluminum rear sprocket, sharpening throttle response and improving low-end pull without requiring any chassis modifications.

Kit Components:

• Front Sprocket: Vortex 3270-15 — 15-tooth, 520 pitch, chromoly steel countershaft sprocket
• Rear Sprocket: Vortex 526AK-45 — 45-tooth, 520 pitch, aerospace-grade aluminum, anodized for durability
• Chain: Vortex 520RV3-110 — 520 pitch X-ring chain, 110 links
• Master Link: Rivet-type master link included

Gearing Specifications:

• Kit Gearing Ratio: 3.00 (15T front / 45T rear)
• OE Gearing Ratio: 2.81 (16T front / 45T rear)
• Gearing Change: 1 tooth down in the front — increases acceleration and low-end torque

Key Features:

• Aluminum rear sprocket reduces unsprung and rotational mass compared to OEM steel
• 520 pitch conversion from OEM — lighter and more efficient than larger-pitch OEM setups
• X-ring chain design minimizes friction and extends service life over standard O-ring chains
• Vortex sprockets manufactured to tight tolerances for precise fit and long wear life
• Anodized aluminum rear sprocket resists corrosion and wear

The Vortex CK6285 is a bolt-on performance upgrade that provides a noticeable improvement in street and track acceleration. All three drive components are pitch-matched at 520 and engineered to work together as a complete system.
