Best Go Kart Chain (2026): #35, #40, #41 & #420 Compared

The best go kart chain is the one whose size matches both your clutch and your axle sprocket, so this guide starts with chain size (#35, #40, #41 and #420) and then compares length, master links and tools. It is written for yard-kart owners replacing a stretched or snapped chain, DIY builders setting up a Predator 212 drivetrain, and minibike owners who share the same parts. Our #1 pick is the Belleone #35 10 ft chain, because it is long enough for any kart layout with spare left over and arrives with a chain breaker and five master links.

The Best Go Kart Chains Compared

1. Belleone #35 Roller Chain 10 ft — Best Overall #35 Chain

Best overall

Why we like it

• Ten feet of #35 covers any kart layout
• Chain breaker and five master links included
• 40Mn carbon steel construction
• Leftover length works as a trailside spare

Belleone #35 roller chain — 10 ft, 320 links, 40Mn carbon steel, breaker plus 5 master links.

The only 10 ft #35 chain that includes a breaker

Seven of the 11 chain-only listings are #35, the size most stock yard karts and minibikes with a #35 clutch use. Two of those seven come in 10 ft lengths, and this Belleone is the only one of the pair that adds a chain breaker and master links. The PGN 10 ft #35 ships with two spare links but no tool, which means buying a breaker separately before you can size it.

Ten feet is far more than a single kart needs, and that is the point. Most single-engine karts use somewhere between 3 and 5 ft of chain, so the remainder becomes a spare for a second kart or a replacement after the first one stretches. The five master links also mean you can rejoin a chain on the trail.

One detail to note: the listing prints the pitch as 0.35 in. Standard #35 chain has a 3/8 in (0.375 in) pitch, and the size label, roller width and pin diameter here are consistent with standard #35, so the figure reads as shorthand. Confirm your clutch and sprocket are #35 before ordering; the listing itself recommends checking.

2. DYC 420 Chain 132 Links — Best #420 Chain Kit

Best #420 chain kit

Why we like it

• Only listing that states a tensile strength
• Also states a 10 hp maximum rating
• Breaker and five clip master links included
• Cut-to-fit from 132 links

DYC RCKIT420132 — #420 chain, 132 links, 4000 lb tensile, 10 hp max, breaker and 5 master links.

The only listing with a strength and horsepower rating

None of the other 16 listings on the shelf put a number on chain strength. This DYC kit states a 4000 lb tensile rating and a 10 hp ceiling, which gives a modified-engine builder something concrete to compare against. A stock Predator 212 sits well under that horsepower figure; a heavily modified engine may not.

The #420 size is common on Chinese ATVs, pit bikes and karts built from their parts, and the listing names Coleman, Baja, SSR, TaoTao, Coolster and similar brands. It shares its 1/2 in pitch with #40 and #41, so it runs on sprockets cut for 40/41/420.

The listing does not state a length in inches. As a rule of thumb, 132 pitches of 1/2 in chain is about 66 in before cutting, but count your old chain rather than guessing.

3. PGN #40 Roller Chain 10 ft — Best #40 Chain by the Length

Best #40 chain

Why we like it

• Longest #40 chain on the shelf
• ANSI #40 single strand, 1/2 in pitch
• Carbon steel stated clearly
• Two connecting links included

PGN #40 roller chain — 10 ft, 239 links, 1/2 in pitch, carbon steel, 2 connecting links.

Twice the length of the other #40 chain on the shelf

Two listings sell plain #40 chain. The AZSSMUK version is 5 ft with 120 links and one connecting link; this PGN chain is 10 ft with 239 links and two connecting links. If you run a larger kart with a long wheelbase, or a shop that maintains several karts, the longer roll is the more practical buy.

The #40 size is the heavy-duty end of the 1/2 in pitch family. It suits torque converter setups and higher-output engines where #35 is marginal. Because #40 rollers are wider than #41 and #420, check that your sprockets are either #40 or labelled 40/41/420.

No breaker is included, so budget for one if you do not already own a chain tool. The listing also does not mention a finish or corrosion coating.

4. LUPING #35 Chain 160 Links — Best for Coleman and Baja Models

Best for named kart models

Why we like it

• Only #35 listing that names specific kart models
• Full pitch, roller and pin dimensions
• Breaker plus five master links
• 160 links is enough for most small karts

LUPING LPCB03 — #35 chain, 160 links, 3/8 in pitch, carbon steel, breaker and 5 master links.

The only #35 listing that names kart and minibike models

The other six #35 listings describe fitment in general terms such as “go karts, mini bikes and scooters”. LUPING lists actual models, including the Coleman CK100 and SK100 go karts and several popular minibikes. If you own one of those, the guesswork drops considerably.

The listing also prints the full set of dimensions, the correct 3/8 in pitch, and states that the breaker works with Predator 79cc to 212cc engine setups. 160 links at 3/8 in pitch is roughly 60 in, which covers most small kart layouts with some to spare.

5. KRGUOD 10T Clutch With #40/41/420 Chain — Best Clutch and Chain Combo

Best clutch and chain combo

Why we like it

• Clutch and chain matched by the seller
• Only combo that states chain link count
• Engagement speed stated (2300 rpm)
• 1-year warranty stated

KRGUOD centrifugal clutch kit — 3/4 in bore, 10T, 40/41/420 chain (96 links), 2300 rpm engagement, 1-year warranty.

The only clutch-and-chain kit that states chain length

Three listings on the shelf pair a 3/4 in bore 10-tooth clutch with a 1/2 in pitch chain: TEANTECH, GYMMEDS and this KRGUOD kit. Only KRGUOD says how long the chain is, 96 links, and only KRGUOD states an engagement speed. Both details matter when planning a build: the link count tells you whether the chain will reach your axle sprocket, and the engagement speed tells you when the kart will start moving.

Buying clutch and chain together guarantees they match. Mixing a #35 clutch with #40 chain is one of the most common first-build mistakes. Remember that the axle sprocket also needs to be 40/41/420; see pick #7.

The listing does not state the chain material or finish, and 96 links (about 48 in) may be short on a longer kart, so measure first. For more on clutch selection, read our go kart clutch guide.

6. CILOYU #35 Roller Chain 4 ft — Best Short #35 Replacement

Best short #35 replacement

Why we like it

• Only 4 ft #35 chain on the shelf
• Red finish stands out from plain steel
• Breaker and spare master links included
• Listing includes alignment advice

CILOYU CO-CH35-128-01R — #35 chain, 4 ft, 128 links, alloy steel, red finish, breaker included.

The only 4 ft #35 chain on the shelf

The #35 chains on the shelf come in 3 ft, 4 ft, roughly 5 ft and 10 ft lengths. Three feet is short for many karts, and 5 or 10 ft leaves a lot of offcut. This 4 ft CILOYU sits in between and suits compact yard karts with a short engine-to-axle distance.

The listing is also honest about its limits: it warns that 128 links is not long enough for some minibikes without adding chain, and it reminds buyers to keep the sprockets aligned. Along with its 3 ft CILOYU sibling, it is one of only two #35 listings with a coloured (red) finish, which some owners prefer for looks.

7. Podoy 60 Tooth Live Axle Sprocket — Best Matching Axle Sprocket

Best matching sprocket

Why we like it

• Only sprocket here that mounts straight to an axle
• 1 in bore with 1/4 in keyway
• Two set screws pre-installed
• Heat-treated steel, electroplated finish

Podoy 60T live axle sprocket — 40/41/420 chain, 1 in bore, 1/4 in keyway, 9-3/4 in OD, two set screws.

The only sprocket on the shelf with a keyed axle bore

Three sprockets appear on the shelf, all for 40/41/420 chain. The two Gekufa sprockets have large centre bores (2 in and 2-1/8 in) and bolt onto a hub; this Podoy sprocket has a 1 in keyed bore and set screws, so it fits directly onto a 1 in live axle. If your kart has no sprocket hub, this is the simpler install.

A 60-tooth rear sprocket with a 10-tooth clutch gives a 6:1 ratio, which favours acceleration and pulling power over top speed. The listing rightly notes that actual speed depends on the clutch sprocket, tyre size and engine. Add the 1/4 in key separately, since it is not in the box.

Go Kart Chain Sizes Explained: #35 vs #40, #41 and #420

Chain size is set by your clutch or torque converter and your axle sprocket, not by preference. Read the number stamped on your old chain’s side plates or the sprocket, or measure the pitch (the distance between pin centres). Our clutch chain guide covers matching in more depth.

• #35: 3/8 in pitch. Light and common on stock yard karts, minibikes and many 79cc to 212cc builds with #35 clutches. Fine for stock engines; marginal for heavily modified ones.
• #40: 1/2 in pitch with the widest rollers of the half-inch family. The heavy-duty choice for torque converters and higher-output engines.
• #41: 1/2 in pitch with narrower, lighter rollers. Common on older karts and light-duty drives.
• #420: 1/2 in pitch, motorcycle-style chain used on Chinese ATVs and pit bikes and many karts built from those parts.
• #219: a small racing-kart chain on a 7.774 mm pitch, used with dedicated racing sprockets. It does not interchange with any of the sizes above, and none of the listings compared here are #219.

Sprockets sold as “40/41/420” are made thin enough to run all three half-inch chains. A sprocket cut specifically for #40 may be too thick for #41 or #420 chain, and no #35 part will mesh with a 1/2 in pitch chain. If you are planning a whole drivetrain, our go kart engine guide explains how engine output affects chain choice.

How to Measure Chain Length

The easiest method is to count your old chain. Lay it flat and count the pins (each pin is one pitch), or measure its length and divide by the pitch. Stretched chain will measure long, so count pins rather than trusting a tape.

Be careful with link counts on listings. Most sellers count pitches, but one #420 listing on the shelf counts inner and outer links separately, which halves the real figure. When in doubt, compare lengths in inches or feet.

For a new build, wrap a piece of string around both sprockets along the chain path with the engine at the middle of its adjustment slots, mark it, and divide by the pitch. Round up to the next whole pitch; with a standard master link the chain must have an even number of pitches. Leave room in the engine mount slots to tension the chain as it stretches.

Chain Tension and Alignment

A chain that is too tight wears bearings and the clutch and robs power; one that is too loose can jump the sprocket and lock the rear wheels. As a general guide, there should be roughly 1/4 to 1/2 in of free play at the middle of the lower run, checked at the tightest spot as you rotate the axle. Follow your kart or clutch maker’s figure if one is given.

The clutch sprocket and axle sprocket must sit in a straight line. Lay a straightedge across both faces; any offset causes the chain to ride up on the teeth and wear unevenly. Check engine mount bolts after setting tension, since they can slip.

Always fit a chain guard. A thrown chain moves fast, and loose clothing or long hair near an unguarded chain is a serious entanglement risk, especially on kids’ karts.

Lubrication and Maintenance

• Lubricate with a chain-specific lube on the inside of the chain while it is warm, then wipe off the excess so it does not fling onto tyres or brake rotors.
• Clean dirt and grit off after muddy or dusty runs; grit plus oil grinds the rollers.
• Inspect for stiff links, cracked side plates and a loose master link clip. The open end of the clip should face away from the direction of travel.
• Replace chain and sprockets together when teeth look hooked or the chain stretches past its adjustment range; a new chain on worn sprockets wears out quickly.

Chain work often goes hand in hand with other rear-end jobs; see our go kart axle guide and go kart brakes guide if you are pulling the axle anyway.

Frequently Asked Questions

Final Thoughts

Identify your chain size from the clutch and sprocket first, then pick a length and make sure a breaker and master links are in hand. For most #35 karts, the Belleone 10 ft chain covers today’s repair and the next one. Browse our go kart parts guide for the rest of the drivetrain.
