To simplify your choice, I’ve listed the top options for your need and their pros and cons. Read on to find the perfect go kart with clutch.

Top 5 Go Kart Clutches

1. Auto-Express Centrifugal Clutch

This racing go-kart clutch works well with independent chains and sprockets. This clutch is recommended for 2–6 horsepower go-kart engines. Installation yields 2200 * 200 revs engagement.

Its major feature is the anti-slip construction that prevents slide during strong acceleration or braking. Kids’ go-karts benefit from its 12 teeth and easy-to-remove teeth sprocket and chain.

It works with 4.5HP and 6HP motorcycles with 35-inch chains. It also has a simple sprocket key to tighten the chains and sprockets to the clutch.

It works great with a 1/2-inch keyway and lasts for years. Its three-leaf spring design keeps it performing well under pressure.

Buying Guide

I prepared a go-kart with a clutch buyer’s guide to assist you in deciding. This should also clear up any confusion concerning go-kart clutches and which one is best for your vehicle. I’ll examine go-kart clutch application, engagement ranges, compatibility, gear ratio, material, components, and pricing.

Application

As you know, centrifugal go kart clutches have fixed gear ratios. Clutches engage at 2,000–2,300 rpm. That implies the clutch engages when the go-kart engine crankshaft rotates at 2,000–2,300 rpm.

Torque converter engagement is much lower. Consider this while deciding whether a clutch is right for your go-kart. Both clutches and torque converters offer benefits, but it’s vital to know which is ideal for your go-kart.

Clutches for Racing Go-Karts

Go-kart clutches feature a wider engagement range than torque converters, making them superior for racing. They respond faster and perform better at greater torques. This is most obvious at higher speeds, hence most racing go karts are with clutch.

For optimal performance, professional go karts with bigger engines employ multi-disk centrifugal clutches. Centrifugal clutches like those in this list are adequate for racing go karts. I’ll explain engagement ranges and compatibility following.

Homemade Go-Kart with Clutch

Race-focused homemade or modified go-karts use clutches well. Because they’re cheap compared to torque converters, if you predict many stop-and-go situations or drive at low speeds, a torque converter may be better.

Off-Road Go-Kart with Clutch

Instead of using a clutch for an off-road go-kart gearbox replacement, explore another option. Low to medium torque levels are typical for off-road go-karts. It frequently occurs at moderate speeds, particularly while ascending rough terrain.

Due to clutch ‘slippage,’ an off-road go-kart clutch is inefficient and short-lived. Go-kart clutch slippage occurs when the clutch is not completely engaged. The clutch will burn and wear out.

Engagement Range

In the product reviews above, the clutch engagement range is commonly mentioned. The clutch engagement range is the crankshaft rotation per minute before the inner components push against the drum and engage.

Go kart clutches engage typically at 2,000–2,300 rpm and completely engage at 2,600 rpm. Anything in between is bad because the clutch slips.

Understanding this range is essential to finding a clutch that fits your engine. Individual clutch engagement ranges are often given as 2300 ± 300. This go-kart clutch engages at 2,000–2,600 rpm.

Compatibility

Make sure the clutch fits your go-kart. Therefore, make sure it fits your engine’s power, crankshaft diameter, and chain size. Check clutch specs carefully.

Engine Output

Each go kart with clutch has an engine output specified for compatibility. Overpowering your go-kart engine may wear out the clutch, which is too tiny. Underpowered go-kart engines may never completely engage the clutch, causing it to slide.

For engine output recommendations, see each product’s description. These clutches typically suggest engine horsepower between 2 and 7 hp.

A go-kart clutch should suit any small to medium engine, provided the parameters are satisfied. These go-kart clutches work with these engines:

• Honda GX160, GX200, GX140, GX120, GC160, GC190, GX200

• Harbour Freight (Greyhound 196cc & Predator 212cc)

• Briggs & Stratton (Models with 2-7 hp power)

• Titan (All versions with 2-7 hp output)

• Tecumseh (Models with 2-7 hp power)

• Plus more…

Crankshaft

Go-kart clutches for smaller and handmade models typically have a 3/4″ hole diameter. The clutch bore is the crankshaft aperture in the middle.

For a precise fit, the crankshaft must also have a diameter of 3/4″ if the bore diameter is 3/4″. The keyway for these crankshafts is 3/16″. Make sure your crankshaft and keyway are compatible before buying a clutch.

Chain

A roller chain links a go-kart clutch to the back sprocket. Your rear and clutch sprocket sizes determine your go-kart chain size.

Make sure that the clutch and rear sprockets use the same chain size. Most go-kart clutches work with #35 or #40/41/420 chains.

Read product specifications carefully to guarantee compatibility since chain size does not always match sprocket teeth.

Gear Ratio

Remember to have the right gear ratio for your go-kart. Divide the rear sprocket teeth by the clutch sprocket teeth to determine the gear ratio.

The gear ratio is 6:1 with a 10-tooth clutch and 60-tooth rear sprocket. Sometimes, this number is one digit: 6.

Remember that lower gear ratios mean quicker go-karts. However, all sections will be stressed more. As a guide, aim for 6:1. Modify the sprockets to modify the gear ratio.

Material

Go-kart clutches are composed of durable high-grade steel. After clutch engagement, it must tolerate friction and heat.

Steel interior pieces include the arrestor spring, bushing, and friction shoes.

Components

You should consider numerous factors while selecting a go-kart clutch. Always remember all the clutch installation pieces. Some clutches don’t have all the pieces, so you’ll need to buy them individually.

This is a brief list of go-kart clutch installation components. Reuse these pieces if you have them. Alternatively, you may buy a go-kart clutch kit or the missing pieces individually.

• 1x Clutch

• 1x Chain

• 1x Keyway

• 2-3 set screws (clutch-dependent)

• One set of tools

Price

A typical go-kart clutch costs $25 to $50, depending on the components. Most clutches without go-kart chains are more costly, and those without extra components are cheaper.

FAQS:

Go-Kart Clutches Engage at What RPM?

Go-kart clutches engage at 2,000–2600 RPM, depending on the clutch and engine.

What Does a Go-Kart Clutch Do?

A go-kart clutch transfers engine power to wheels. When the engine RPM goes below a particular threshold, it disengages.

Does a Clutch Accelerate Go-Karts?

A working clutch may boost acceleration and performance, but it won’t make a go-kart quicker.

Other locations may have varying height and age limits. Before coming, verify with the location to make sure you qualify.

How Do You Repair a Go-Kart Clutch That Slips?

Go-kart clutches that slide usually need spring tension adjustments or clutch shoe or drum replacement.

How Many Teeth Should My Go-Kart Clutch Have?

A go-kart clutch usually has 10–12 teeth, depending on the engine and clutch.

Can a Sliding Clutch Be Tightened?

A sliding clutch may be tightened by adjusting spring tension. Avoid overtightening the clutch, since this might create additional troubles.

Conclusion

After reading this, I found that choosing a go-kart racing clutch with all the necessary information is easy. Our top five selections fit all budgets and racing demands, but Auto-Express Centrifugal Clutch stands out for its amazing design and adjustable trigger that makes driving more smooth.
