The DID 428H G&G is designed for racers who want maximum performance with minimal rotating weight. Unlike sealed O-ring chains, the 428H uses a non-O-ring construction to reduce drag and friction — making it ideal for sprint and shifter kart racing where throttle response and power transfer matter.
The heavy-duty construction provides increased tensile strength to withstand the shock loads and extreme RPM of 125cc shifter engines. Gold outer and inner plates not only give it a premium appearance but also improve corrosion resistance in demanding racing environments.
If you want the lightest, most responsive 428 chain option for competitive karting, this is the go-to choice.
Key Features:
• Best-Selling #428 Shifter Chain – Proven on high-output kart engines
• Heavy-Duty Construction – Built for extreme load and shock resistance
• High Tensile Strength – Handles high RPM and aggressive shifting
• Non-O-Ring Design – Lower drag and lighter weight for racing performance
• Gold Outer & Inner Plates – G&G finish for corrosion resistance and premium look
• Includes Clip-Style Master Link – Simple installation
