Choosing the best Predator 212 clutch comes down to one decision first: a simple centrifugal clutch or a 30-series torque converter. This roundup is for mini bike and go-kart builders running a Predator 212 or a 196–224cc clone with a 3/4″ crankshaft who want the drive side matched to the engine, the chain and the job. Our #1 pick is the Youxmoto 30 Series Torque Converter, because its listing gives the most complete fitment, engagement and installation detail on the shelf.

The Best Predator 212 Clutches and Torque Converters
1. Youxmoto 30 Series Torque Converter — Best Overall
A complete 30-series kit with clear fitment warnings, a stated engagement range and a two-year warranty.
$56.99as of Oct 26, 2026 5:28 am EDT
Check price on AmazonWhy we like it
- Names Predator 212, 224 and Hisun 196 as fits
- Warns plainly that 20mm crankshafts will not fit
- States engagement near 2350 rpm, adjustable with springs
- Ships with both 10-tooth and 12-tooth sprockets
- Two-year warranty stated on the listing
| Specification | Details |
|---|---|
| Type | 30-series torque converter (TAV2-style replacement) |
| Bore | 3/4″ (19.05mm) driver; 5/8″ driven pulley, 6″ overall |
| Chain size and teeth | 10T for #40/41/420 and 12T for #35 (chain not included) |
| Engagement | About 2350 rpm; listing says 1200–3100 rpm with optional springs |
| Included | Driver, driven, belt, plastic cover, aluminum mount plate, hardware with three screw kits |
| Belt | 27.76″ long, 3/4″ wide; 6-15/16″ to 7″ center distance |
Youxmoto 218353A-style 30 Series — 3/4″ driver, 10T/12T sprockets, ~2350 rpm engagement, full kit minus chain and riser plate.
The most complete fitment notes on the shelf
Torque converter listings tend to repeat the same template, so the details that help you install one are what separate them. This listing covers belt direction (arrow side down), the fact that the plastic cover has no pre-cut chain hole, and that some frames need a riser plate for chain clearance. Only 2 of the 21 listings mention a riser plate at all, and this is one of them.
It is also one of 6 listings that warn the 3/4″ bore will not fit a 20mm (0.787″) crankshaft, a common trap with generic 196cc and 7.5 HP clones. Add the stated engagement figure and a two-year warranty, which only 3 listings on the shelf claim, and it gives a builder the most to work with before ordering.
What it does not include: a chain or a riser plate, and the replacement springs for changing engagement are sold separately.
Pros
- Clear fitment and 20mm warning
- Both common sprocket sizes included
- Engagement range stated
- Two-year warranty stated
Cons
- Chain not included
- Cover must be cut for the chain
- Riser plate may be needed and is extra

2. ILONPA 10T Centrifugal Clutch with #420 Chain — Best Centrifugal Clutch
A 3/4-inch, 10-tooth dry clutch that ships with a 96-link #420 chain and a stated engagement speed.
$25.99as of Oct 26, 2026 5:28 am EDT
Check price on AmazonWhy we like it
- States engagement at 2300 rpm, plus or minus 300
- Includes a 48-inch #420 chain and connecting link
- Spells out a step-by-step break-in routine
- Flags that 20mm crankshafts are not compatible
| Specification | Details |
|---|---|
| Type | Centrifugal dry clutch |
| Bore | 3/4″ (19.05mm) with 3/16″ keyway |
| Chain size and teeth | 10T for #40/41/420; supplied chain is #420 |
| Engagement | 2300 rpm, plus or minus 300 |
| Included | Clutch, #420 chain (96 links), connecting link |
| Engine range | Listing states up to 6.5 HP |
ILONPA BUTOC003S — 3/4″ bore, 10T, #420 chain included, 2300 ±300 rpm engagement.
A chain in the box and a stated engagement band
Of the 11 centrifugal clutch listings we compared, 5 include a chain. This one adds a connecting link and explains that its supplied chain is #420, which has different roller and inner-width dimensions from #40 and #41. That note saves a mismatch if your axle sprocket is cut for a different chain.
It is also one of only 4 listings on the shelf with written break-in steps: a few no-load engagements, then gradual loaded runs with cool-down gaps. New clutch shoes need that bedding-in to stop slipping and smoking, and few sellers say so.
The listing does not state a mounting bolt or washer in the package, so plan to reuse yours or buy one.
Pros
- Chain and connecting link included
- Engagement speed stated
- Clear break-in instructions
- Explicit 20mm warning
Cons
- No mounting bolt listed in the box
- Rated only to about 6.5 HP
- Not a fit for 5/8 or 1 inch shafts

3. GYMMEDS 30 Series Torque Converter — Best for Mixed Hardware Threads
A 30-series kit that ships with both UNF and metric screw sets, plus both common sprocket sizes.
$58.66as of Oct 26, 2026 5:28 am EDT

| Bore | 3/4″ straight crankshaft; listing also lists a 5/8″ pulley |
| Chain size and teeth | 10T for #40/41/420 and 12T for #35 (chain not included) |
| Engagement | About 2350 rpm; 1200–3100 rpm with optional springs |
| Included | Driver, second pulley, belt, cover, aluminum plate, hardware |
GYMMEDS 30 Series — 3/4″ bore, 10T/12T sprockets, ~2350 rpm engagement, UNF and metric screws.
The only listing that explains thread standards
The Predator 212 crankshaft end is tapped with a fine UNF thread, while many imported clones use metric. This is the only listing among the 21 that explains UNF versus metric screws and tells you which set to try first. If you swap engines often or are not sure what is in your frame, that detail removes a trip to the hardware store.
Otherwise it is a standard TAV2-style kit. Like most of the 10 torque converter listings, it leaves out the chain, and it does not mention riser plates or cover cutting, which you should still expect on many frames.
Pros
- UNF and metric screws supplied
- Engagement range stated
- Both sprocket sizes included
Cons
- Chain not included
- Only one belt in the box
- Pulley list wording is unclear

4. ILONPA 12T Centrifugal Clutch with #35 Chain — Best #35 Chain Setup
A 12-tooth dry clutch for lighter #35 chain, supplied with 4 feet of chain, set screws and a link.

- 12-tooth sprocket sized for #35 chain

|---|---|
| Type | Centrifugal dry clutch |
| Bore | 3/4″ (19.05mm) with 3/16″ keyway |
| Chain size and teeth | 12T for #35 (3/8″ pitch) |
| Engagement | 2300 rpm, plus or minus 300 |
| Included | Clutch, 4 ft #35 chain, 2 set screws, connecting link |
| Engine range | Listing states 2–7 HP |
ILONPA BUTOC004S — 3/4″ bore, 12T for #35 chain, chain and set screws included, 2300 ±300 rpm.
For karts already running #35 chain
Many yard karts and older frames use #35 chain, which is lighter than #40/41/420. Four centrifugal listings on the shelf offer a 12-tooth #35 option, and this one bundles the chain and set screws, which the bare 12T clutches from Vashly and KRGUOD do not.
A 12-tooth sprocket also gears slightly taller than a 10-tooth with the same rear sprocket, so expect a little more top speed and a little less pull from a stop. If your kart struggles on hills, the 10T version or a torque converter is the better match.
Pros
- Chain and set screws included
- Engagement speed stated
- Break-in guidance included
Cons
- #35 chain is lighter duty than #40/41
- No bolt or washer listed
- Taller gearing can bog heavy karts

5. ATRACYPART Super 30 Series Driver — Best Driver Upgrade

| Power rating | Listing states support up to 15 HP |
ATRACYPART AP-A2373 Super 30 — 3/4″ driver for existing 30-series kits, >2500 rpm engagement stated.
The only driver-only upgrade on the shelf
The other torque converter listings are sold as kits. This is the one sold as a driver alone, aimed at owners whose stock driver slips, hunts for rpm or makes noise. A later engagement point lets a modified engine reach more of its torque before the belt grabs, which suits a kart with a stage kit or bigger carburetor.
The 15 HP figure is the listing’s own claim, and the stock 212 is far below that. Treat it as headroom, not a reason to skip checking the driven pulley and belt, which this product does not replace.
Pros
- Simple swap on an existing kit
- Higher stated engagement point
- 24-month warranty stated
Cons
- Not a complete torque converter
- No sprocket or belt included
- Spec detail is thin

6. Vashly 10T Centrifugal Clutch — Best Simple Bare Clutch

| Included | Clutch, 2 bolts, 2 washer kits, 2 wrenches |
| Intended use | Single-wheel-drive karts with tires up to 15″ tall |
Vashly VASH-10T — 3/4″ bore, 10T for #40/41/420, reversible mounting, chain not included.
Reversible mounting and a realistic use case
This is the only listing on the shelf that says the clutch can mount inward or outward on the crankshaft, which helps line the sprocket up with the axle without spacers. It also states a sensible limit, single-wheel-drive karts on tires no taller than 15 inches, which is useful honesty about where a dry clutch belongs.
It is a bare clutch: no chain, and the listing gives no keyway size or engagement speed for the clutch itself. If you already have chain and know your sprocket line, it covers the basics.
Pros
- Mounts in either direction
- Spare bolt and washer set
- Clear tire-size guidance
Cons
- Chain not included
- No clutch engagement figure
- Keyway size not stated

IPARTS EXPERT CL-RN005 30 Series — 3/4″ driver, 10T/12T sprockets, three belts, chain not included.
Spare belts from day one
Only 2 of the 10 torque converter listings include three belts, and this is one. Belts are the wear item in any CVT, and new belts often glaze during break-in or after a misaligned first install, so having spares on the shelf keeps a project moving.
The listing does not give an engagement speed, and it says plainly that the kit is a replacement design, not Comet-made. For a builder who wants a complete kit and spare belts in one order, it is a reasonable pick lower on the list.
Pros
- Three belts included
- Full kit with cover and plate
- Both sprocket sizes
Cons
- No engagement speed stated
- Chain not included
- Some mechanical skill needed to fit

Centrifugal Clutch vs Torque Converter on a Predator 212
A centrifugal clutch is a single fixed gear. Weighted shoes fly outward as rpm rises and grip a drum with the sprocket attached. It is compact, cheap and simple, which suits light karts, flat ground and kids’ builds. The trade-off is that you pick one ratio: gear it for top speed and it bogs and slips on hills; gear it for pull and the top end runs out early.
A 30-series torque converter is a belt-driven CVT. The driver pulley on the crankshaft and the spring-loaded driven pulley on a jackshaft change ratio as speed and load change. That gives stronger launches, better hill climbing and a higher top speed from the same engine, at the cost of more parts, a belt to replace and a few inches of extra mounting space.
Rough rule: if the kart carries an adult, sees grass or hills, or runs a modified engine, a torque converter is usually worth it. For a light kart on pavement or a budget first build, a centrifugal clutch is fine. Our Predator 212 torque converter guide covers the setup in more depth, and the Predator 212 clutch guide explains dry clutches in detail.
How to Match Bore, Keyway and Chain
Bore and crankshaft
Every listing in this roundup is built for a 3/4″ (19.05mm) straight crankshaft with a 3/16″ keyway, which is what the Predator 212 uses. None of the 21 listings offers a 5/8″ or 1″ bore, so if your engine has one of those shafts you need a different part. Watch for 20mm (0.787″) shafts on many generic 7.5 HP clones: they look close to 3/4″ but will not accept these clutches. Measure with calipers before ordering. See the Predator 212 engine guide for the stock shaft details.
Chain size and tooth count
#40, #41 and #420 chains share a 1/2″ pitch and usually run on the same 10-tooth sprocket, though roller size and inner width differ, so match the chain to your axle sprocket. #35 chain is a 3/8″ pitch and needs the 12-tooth option. Fewer clutch teeth gives more pull and less top speed; more teeth does the opposite. Match the chain to the rear sprocket you already have, then choose the tooth count from your gearing goal.
What is in the box
Eleven of the 21 listings say outright that the chain is not included. Torque converter kits usually include the driver, driven, belt, a cover and a backing plate, but not the chain or a riser plate. Centrifugal clutches vary: some ship with bolt, washer and set screws, others with nothing but the clutch.
Engine size limits
Read the stated horsepower or displacement range. Most listings cover 2–6.5 or 2–8 HP engines, but the Bravex 10T clutch on this shelf states it is for engines no larger than 200cc, which would rule out a 212. A modified 212 with a stage 2 kit puts more load through the drive, so lean toward a torque converter or an upgraded driver.
Installation, Break-In and Maintenance
- Align the chain. The clutch sprocket and axle sprocket must sit in a straight line. Misalignment wears chains and sprockets fast and can throw the chain.
- Secure the bolt. Use the correct thread (UNF on a Predator 212), a washer, and thread locker. A loose clutch bolt is a common cause of damage.
- Break in the shoes or belt. Several listings describe a few no-load engagement cycles followed by gradual loaded runs with cool-downs. Skip this and a new clutch can slip and smoke.
- Check belt direction. On torque converters, follow the arrow on the belt as the listing describes, and keep the 6-15/16″ to 7″ center distance.
- Lubricate where specified. Some centrifugal clutches ask for oil above the circlip before installation; never oil the shoes or drum surface.
- Inspect regularly. Look for glazed or cracked belts, worn sprocket teeth, chain stretch and heat discoloration on the drum.
Always run with the chain guard and torque converter cover fitted, keep loose clothing and hair away from the drive, and wear a helmet whenever you test the kart. If you are planning more power, our best Predator 212 upgrades roundup lists the parts that pair with a stronger drive.

Final Thoughts
For most Predator 212 builds, a complete 30-series torque converter such as the Youxmoto kit is the strongest all-round choice, while the ILONPA 10T clutch with chain is the easy pick for a light kart on a budget. Whatever you choose, confirm the 3/4″ bore, chain size and tooth count before ordering. For fitment questions on dry clutches, see our go-kart clutch for Predator 212 guide.
