Everything You Need to Know About Go Kart Chains

If you’re a go-kart enthusiast or just getting started in the world of karting, you know that every component plays a crucial role in the performance and functionality of your machine. One such component that often goes overlooked but is absolutely essential is the go-kart chain. In this article, we’ll delve into everything you need to know about go-kart chains, from their types and sizes to maintenance tips and more.

Types of Go-Kart Chains:

1. #35 Chain: This is one of the most common types of chains used in go-karts. It’s known for its durability and strength, making it suitable for various applications, including recreational go-karts and racing karts.

2. #40 Chain: Slightly larger than the #35 chain, the #40 chain offers even more strength and durability. It’s commonly used in heavier go-karts or those with higher horsepower engines.

3. #25 Chain: This chain is smaller and lighter than the #35 and #40 chains, making it ideal for lighter weight go-karts or those with lower horsepower engines. It’s often used in entry-level or junior racing classes.

Chain Size and Length:

When selecting a go-kart chain, it’s essential to choose the correct size and length to ensure proper fit and performance. The size of the chain refers to its pitch, which is the distance between the pins. Common sizes include 1/2 inch (#35 and #40 chains) and 1/4 inch (#25 chain). Additionally, the length of the chain will depend on the size of the sprockets and the wheelbase of your go-kart.

Maintenance Tips:

Proper maintenance of your go-kart chain is crucial for optimal performance and longevity. Here are some essential maintenance tips:

Keep the chain properly lubricated: Regularly lubricating the chain with a high-quality chain lubricant will help reduce friction and wear, prolonging its life.

Check for tension: Ensure that the chain is neither too loose nor too tight. A properly tensioned chain will help prevent premature wear and damage to other components.

Inspect for damage: Regularly inspect the chain for signs of wear, such as stretched links, kinks, or missing rollers. Replace the chain if any damage is detected to avoid potential issues on the track.

Upgrades and Modifications:

Depending on your go-kart’s specific requirements and performance goals, you may consider upgrading or modifying your chain. Upgraded chains with features such as lightweight construction or enhanced strength can improve acceleration, top speed, and overall performance. Additionally, aftermarket sprockets and gear ratios can further optimize your go-kart’s performance by fine-tuning its power delivery and gearing.


In conclusion, the go-kart chain is a critical component that directly impacts the performance and reliability of your machine. By understanding the different types, sizes, and maintenance requirements of go-kart chains, you can ensure that your kart operates at its best every time you hit the track. So, don’t overlook the importance of the humble go-kart chain and make sure to give it the attention it deserves for a thrilling and successful racing experience.
