Description

2532 Aluminum Sprocket Chain Guard – For #35, #219, and #40 Chains


The 2532 SK Aluminum Rear Sprocket Chain Guard is a must-have upgrade for serious go-kart racers running #35, #219, or #40 pitch chains. Crafted from lightweight, durable aluminum and anodized in black, this chain guard is designed to protect your sprocket and keep your chain securely in place under aggressive driving conditions.


Whether you're running a high-revving Briggs 206 or a Honda GX200 clone, this guard adds crucial protection against track debris, curb strikes, and drivetrain torque twist—common causes of thrown chains and race-ending failures.


Key Features:

  • Material: Lightweight, high-strength aluminum
  • Finish: Black anodized for corrosion resistance and durability
  • Mount Pattern: Fits standard 6-point sprocket hubs
  • OD: 8.75" (covers most common race sprockets)
  • Includes: 4-piece guard set with hardware for easy installation
  • Design: Two large rings and stanchions maintain clearance between the sprocket and the guard


Compatibility by Chain Type:

  • #219 Chain: 64–88 tooth sprockets
  • #35 Chain: 59–70 tooth sprockets
  • #40 Chain: 42–53 tooth sprockets

The guard may still fit larger tooth counts, but the chain may sit outside the protective diameter.


Why Use a Sprocket Chain Guard?

  • Prevents chain derailment caused by torque flex or rough tracks
  • Shields sprocket teeth and chain from curbs, debris, and impacts
  • Adds confidence and reliability during high-stakes racing
  • Helps prevent race-ending mechanical failures


Tech Notes:

  • Mounts to most standard 6-bolt sprocket hubs
  • Requires longer sprocket bolts due to additional guard thickness
  • Outer diameter: 8.75” (222mm)
  • Includes full mounting hardware set


Ideal For:

  • Racing Go-Karts
  • Briggs LO206, Honda Clone, or other 4-stroke classes
  • Tracks with curbing or high-contact environments
  • Drivers focused on drivetrain reliability and race consistency

FAQ

1. What does this sprocket guard protect against?

It protects the rear sprocket and chain from curb hits, debris, and drivetrain torque flex—common causes of thrown chains or sprocket damage during races.


2. What chains and sprockets is it compatible with?

It fits:

  • #219 chain: 64–88 tooth sprockets
  • #35 chain: 59–70 tooth sprockets
  • #40 chain: 42–53 tooth sprockets
    Larger sprockets may still fit, but the chain may extend beyond the guard's OD.


3. What is the outer diameter of the chain guard?

The guard has an outer diameter of 8.75 inches, providing protection within a wide range of sprocket sizes. Once mounted, total OD is approximately 9 inches (230mm).


4. Does it fit all go-karts?

It fits any kart with a standard 6-bolt sprocket hub pattern. Most racing go-karts and many mini bike setups with similar hubs are compatible.


5. What’s included in the kit?

Each kit includes:

  • Two aluminum guard rings
  • Standoffs and spacers
  • Mounting hardware (bolts, nuts, washers)


6. Do I need longer bolts to mount this?

Yes, the additional width from the guard means you’ll need longer sprocket bolts than what’s typically used with a standard chain setup.
