5 Pieces Clutch Spacer Shim Washer 3/4″ Shaft for 30 Series Torque Converter
Brand: ADJUADN
Designed for 3/4 inch engine shafts, these aluminum spacers align clutches and torque converters for Coleman CT200U, CT200U-EX, BT200X, RB200 minibikes, and KT196 go-karts. The kit also suits numerous 196cc and 208cc engines used in mini bikes and small go-karts. The spacers help fine-tune alignment, reducing clutch wear and minimizing the risk of drive-system damage. They are suitable for Predator 212cc, Honda GX160, GX200, and similar engines when paired with a 30 Series torque converter.
Key benefits include improved clutch engagement, smoother operation, and a safeguard against misalignment that can cause premature wear. Users should confirm the outer diameter and bore to ensure a proper fit with their specific clutch and converter stack. The lightweight aluminum construction supports repeated use without adding excessive weight to the drive train.
JEGS Mid-Plate Shim Kit For 7/16″ Converter Bolts
Brand: JEGS
Purpose-built for proper spacing of torque converters with 7/16″ bolts, this kit ensures correct input shaft and pump engagement. It includes three shims in varying thickness (.060″, .125″, .250″) suitable for both 1/8″ and 1/4″ mid-plates. Made in the USA, the kit emphasizes quality components and precise assembly to maintain proper clutch alignment and reliable power transfer.
Use considerations include checking whether your mid-plate or mounting hardware matches 7/16″ bolt patterns, and selecting shims that achieve the target clearance without introducing binding. This kit is a practical upgrade for experienced hobbyists performing performance tweaks or rebuilds, particularly on Predator, Coleman, or Baja mini-bike configurations that rely on 30 Series torque converters.
RZEOZU 30 Series Torque Converter Kit With Bolts
Brand: RZEOZU
Specifically marketed for 3/4″ shaft engines, this kit targets the 30 Series torque converter drive system used on Predator 212cc, 196cc, GX160, and GX200 engines. The package includes a 45 mm metric-thread bolt, a 50 mm standard-thread bolt, a custom washer, and three gaskets, enabling a complete replacement or refresh of the spacer and mounting hardware. The kit’s emphasis is compatibility and ease of installation when rebuilding or upgrading a small-block torque converter assembly.
Important considerations include verifying shaft diameter and thread compatibility with your existing bolts. While providing a full set of components, this kit is best suited for users performing a mid- or full assembly of the torque converter drive train, ensuring secure engagement and minimizing friction losses that can affect acceleration and clutch performance.
VCUJSUC Universal Clutch Spacer Shim Washer 3/4″ Shaft
Brand: VCUJSUC
These universal spacers support 3/4″ shaft configurations across a broad range of mini bikes and go-karts, including Predator 212cc, Coleman CT200U, BT200X, and KT196. The kit is described as versatile for non-hemi Predator engines and a variety of 196cc to 208cc powerplants. Twelve pieces provide multiple thickness options for precise alignment and clutch engagement, supporting safer operation and reduced wear on the drive train.
Practical notes include confirming the engine family and clutch model before ordering, as well as ensuring that the spacers will sit flush with both the clutch and the converter. The 3/4″ size is common on many performance mini-bike builds, making these spacers a go-to option for hobbyists performing a tune-up or upgrade to improve alignment accuracy.
MSMUSAS 12PCs Clutch Spacer Shim Washer 3/4″
Brand: MSMUSAS
This set targets a universal 3/4″ shaft for non-hemi Predator engines and compatible Mini Bike models like Coleman CT200U/BT200X and KT196.

The product is positioned as a practical fix for improving clutch firmness and reliability in driving applications that demand consistent engagement and reduced risk of misalignment.
When selecting spacers, considerations include ensuring you have the correct shaft diameter, verifying that the kit contents match your clutch bolt pattern, and confirming compatibility with your particular mini bike model. These spacers play a supporting role in reducing heat buildup and protecting the drivetrain from misalignment-induced wear, making them a sensible maintenance upgrade for older or high-mileage builds.
Buying Guide: Key Purchase Considerations
- Engine and shaft compatibility: Confirm the shaft diameter (3/4″ is common for many 30 Series systems) and the bolt pattern on your torque converter and mid-plate.
- Material and finish: Aluminum spacers offer light weight and good corrosion resistance; ensure the finish is suitable for outdoor use on bikes and go-karts.
- Thickness options: Many kits include multiple thicknesses to tune clearance, alignment, and engagement. Choose a kit that provides the range you anticipate needing.
- Mid-plate compatibility: If your setup uses mid-plates, verify that the included shims fit standard 1/8″ or 1/4″ plate thicknesses and bolt sizes.
- Installation considerations: Proper tightening torque and installation sequence protect the clutch system. Avoid overtightening that could cause thread damage or warping.
- Kit completeness: Some sets include bolts, gaskets, and washers; others are spacers alone. Decide if you need a full hardware kit or just spacers.
- Brand and build quality: Reputable brands with USA-made components often provide better tolerances and durability, reducing the risk of diaphragm wear or misalignment.
- Intended use: For performance tuning, select spacers that let you achieve precise clutch alignment, ensuring smooth engagement under load and reducing belt wear.
- Maintenance implications: Regular inspection of spacers and bolts prevents wear-induced misalignment, which can affect acceleration, braking, and safety.
- Return and compatibility policies: Check return windows and verify engine model compatibility to avoid mismatches after purchase.
