212CC Torque Converter 6.5 HP 3/4" Go Kart Mini Bike Comet Clutch 10T 40/41 and 12T 35 Chain Predator Driver Pulley Replacement Set - 30 Series

I’m really happy with this 212CC torque converter kit! The materials feel strong and durable, and the machining quality is excellent. After installation, my go kart runs smoother with better low-end torque and faster takeoff. The set includes everything you need, and it’s easy to install even for someone with basic tools. I’ve been using it for several rides now, and it still performs perfectly without slipping or overheating. A solid and reliable replacement set that’s absolutely worth the money!

This 212CC torque converter kit is excellent quality and works flawlessly with my 6.5HP engine. The installation was straightforward, and all parts fit perfectly right out of the box. The clutch engages smoothly, and the acceleration feels much more responsive than before. It’s a solid, durable setup that performs just like the original Comet clutch but at a much better price. Definitely a must-have upgrade for anyone running a go-kart or mini bike!

Worked great on my CT200U with a Predator 212, no issues with the throttle, easy to install but some of the bolts didn't align correctly on the 212 so you will have to source some different bolts.

Juggernaut torque converter works great and was pretty simple to install to be honest, just needed a riser plate, engages super good, smooth power, has held up to hard launches with a built motor, alignment is good, looks amazing, and fit great, beats the 300 on gps, very good value for the money

I recently installed the 212CC 6.5 HP torque converter kit on my Predator 212 minibike, and after a few weeks of testing, I’m impressed — it’s one of the best performance upgrades I’ve made for under $100. ⸻ First Impressions & Build Quality Straight out of the box, the kit looked well-machined and thoughtfully packaged. All the components — the driver pulley, driven pulley, belt, spacers, and bolts — came clean and smooth, with no obvious casting flashes, burrs, or defect edges. The aluminum surfaces have consistent finishes, and the pulleys spin freely without noticeable wobble. Everything was clearly labeled, and the parts matched the spec sheet provided. One thing I appreciated: the pulleys are anodized, which seems to protect them from corrosion and minor scratches. Even after a few ride tests, the surfaces are still bright and sharp. ⸻ Installation & Fitting I set aside an afternoon to install it, expecting a fair amount of custom work. Fortunately, the kit is mostly plug-and-play with only minor tweaks needed. • Backplate alignment: The backplate’s holes lined up almost perfectly with my stock engine block, needing only small adjustments, not full re-drilling. • Shimming and spacing: I used a feeler gauge to check runout and shim clearance. A few thin washers got the driver parallel to the crank and avoided belt rubbing. • Torque and securement: I used blue Loctite on the main shaft bolt and torqued it to spec. Everything held tight. • Belt path & guard clearance: I checked the path carefully and trimmed a bit off the inside lip of my engine cover so the belt wouldn’t rub. • Break-in: I ran the engine gently for the first 10 minutes, keeping throttle light, to let everything seat before doing full-throttle runs. By the time I was done, I felt confident in the mounting and clearance. No weird noises or binding. ⸻ Performance & Behavior Once I hit the throttle, the difference was obvious: • Smoother engagement: The torque converter transitions more gradually than a clutch — no sudden shocks or jolts. Launches feel more controlled. • Wider usable powerband: The engine feels more flexible at low RPM, with less bogging in tight turns or steep terrain. • Climb and load: On uphill sections with a passenger, the belt stayed solid without slipping. Even heavy load didn’t push it past its limits in normal terrain. • Top end behavior: At full throttle, the unit seems to shift out close to where I expect it to, giving a strong top-end feel without being overly aggressive. • Heat & longevity: After 30+ minutes of continuous riding, the pulleys were warm but not hot, and the belt didn’t smell burnt. Checked it afterwards and saw minimal wear — no glazing or edge cracking. Over multiple sessions, performance stayed consistent. No drift in belt alignment or slop in the pulleys. ⸻ Strengths, Weaknesses & Suggestions Strengths • Great value for what you get — drivers, driven, belt, hardware all included • Smooth, user-friendly operation with noticeable gains in low-end torque • Durable finish and minimal wear after regular use • Flexible enough for riders with intermediate mechanical skill (tweaking, shimming, etc.) Weaknesses / Watch-Outs • Some small adjustments might be needed (backplate alignment, cover clearances) • Belt tension and path must be precise — misalignment causes premature wear • Hardware quality is good, but I replaced a few bolts with stronger grade from my spare stash • Not a plug-and-play upgrade for absolute beginners; some mechanical knowledge helps Suggestions for best results 1. Use blue or red Loctite on all critical bolts. 2. Double-check belt alignment under load before final torqueing. 3. After first use, re-inspect alignment and tighten again as needed. 4. Keep spare belt and hardware in your tool kit — it gives peace of mind on long rides. ⸻ Final Verdict This 212CC 6.5 HP torque converter is an excellent upgrade for anyone wanting smoother acceleration, better hill-climbing, and more usable power in a small engine setup. While it’s not completely drop-in flawless (you’ll want to double-check alignment and make minor clearances), the results are well worth the effort. In value, performance, and durability, I’m giving this kit a 5-star rating, especially for intermediate DIY mechanics.

In summary, there are significant safety issues with the 212CC Torque Converter. I installed the 212CC Torque Converter on a 6.5 hp 212 Predator engine (rear-mounted); all parts are used to power a metal-framed go-cart. The Torque Converter kit included all the parts needed to install the torque converter, but the kit also included additional bolts that were not even meant for any part of this installation (parts that did not even fit any aspect of the kit). The 212CC Torque Converter was installed fairly quickly, but the provided plastic cover had no place for the chain to pass-through it (a major oversight), meaning the plastic protective cover cannot be installed without cutting a hole in the plastic cover to fit the chain configuration. I installed and tested the 212CC Torque Converter without the cover to make sure it worked before cutting a chain hole in the plastic protective cover. After only a few minutes of running, the 212CC Torque Converter’s drive pulley totally and unexpectedly disintegrated, sending parts flying over a 100-yard radius. One part hit me in the arm with enough force to lead to significant bruise and pain (despite wearing a winter coat). I am so thankful that the flying parts did not hit my head! The drive pully disintegrated, even leading to the engine drive shaft threats being stripped. The drive shaft threads need to be retapped to work again. All but the brass washer was recovered, and it appears the disintegration started with the drive pully springs. The drive pully springs appear like they were forcefully pulled out of their connection leading to the pully flying apart. I cannot express how concerning the torque converter kit (drive pulley) failure is to me. A safety cover is meant to be used, but the safety cover cannot be mounted without cutting a chain hole in it. In summary, the drive pully seems poorly made, and the safety cover is certainly not made to cover any chain driven devices.

What an amazing product. Perfect for my Ct200uex (with a riser). I feel like most of the bad reviews are folks the installed it incorrectly. All the fasteners are left loose so you can swap the sprocket for a #35 chain, so check everything before your first ride. I'm really happy it came with American fasteners for predator engines. I literally bolted it together and it works perfectly even after several hours of mobbing the neighborhood. The belt seems to be mid, as after a few hours its looser and noticeably wearing. I ordered some 5959 belts because Google AI said they're interchangeable and the 5959 belt is more durable. So I recommend ordering some spare belts. You will need a riser plate if you're putting this in a minibike. My 224 predator minibike is pulling wheelies off the line and went from 36 to 49 phone tops speed. The clutch on the engine is noisy, that's probably my only real complaint. It's kinda "clacky" at idle, where as the super 30 "juggernaut" is quiet. But still for the money 10/10 recommend

This 212CC 6.5HP pair converter is an excellent replacement option for go karts or mini bikes. Installation was simple and performance improved significantly, with smoother and more powerful acceleration. Includes 10T and 12T pulleys compatible with 40/41 and 35 chains, which offers great versatility. The materials are resistant and durable, perfect for Predator engines and the like. It works wonderfully and is worth every penny. 🏎️⚙️🔥
