Description
Precision Adjustment: #428 Chain Offset Half Link
Solve your chain tension headaches with the Universal Parts #428 Offset Link. Also known as a "half link," this specialized component allows you to adjust your chain length by a single pitch rather than the standard two. It is the essential hardware for custom builds where the rear wheel or motor position is fixed, providing that perfect middle ground between a chain that is too loose and one that is too tight.
Technical Performance Features
- High Tensile Strength: Engineered with an ultimate tensile strength of 18.0 kN (4091 LB), providing the durability needed for high-torque powersports applications.
- Precision Machined: Features a standard 12.70mm pitch and 8.51mm roller diameter, ensuring a smooth mechanical mesh with any standard #428 drive sprocket.
- Corrosion Resistant: Treated steel construction designed to withstand the grit, mud, and moisture typical of off-road ATV and dirt bike environments.
- Essential for Fixed Drive Bases: The go-to solution for Go-Karts and Mini-Bikes where slide-adjustments are limited or non-existent.
Comprehensive Fitment Guide
This offset link is a universal component for any vehicle utilizing a #428 pitch drive chain:
| Vehicle Category | Typical Applications |
|---|---|
| Dirt Bikes / Pit Bikes | 110cc, 125cc, and 150cc Chinese and Japanese models |
| ATVs & Quads | Utility and sport quads using #428 final drive |
| Go-Karts | Trailmaster, Hammerhead, and custom predator-engine builds |
| Mini-Motos | Street-legal small-bore bikes and pocket rockets |

Mechanic's Note: If your chain adjusters are maxed out but the chain is still too loose, this half link is exactly what you need.
Installation Tip: Always ensure the cotter pin or clip is seated fully and facing away from the direction of travel.
Pro Tip: This is a great time to inspect your Drive Sprockets for "hooking"—a worn sprocket will chew through a new link in no time!
