Performance Manufacturing CGBKM Metric Chain Guard Bolt Kit - 8mm x 1.25 Pitch - Clone / 4-Stroke

Securing your drivetrain is non-negotiable for track safety, which is why leading go kart suppliers trust the Performance Manufacturing CGBKM Metric Chain Guard Bolt Kit for rock-solid mounting. Engine vibrations at 7,000 RPM will instantly back out inferior hardware, leading to catastrophic chain misalignment or guard failure. This kit utilizes high-grade 8mm x 1.25 pitch button head cap screws paired with internal locking washers to guarantee your chain guard stays exactly where it belongs, lap after punishing lap.

Essential Hardware for Motor Kart Racing

In the high-stakes environment of motor kart racing, every component matters. Just as you wouldn't compromise on your catch cans or wheel discs, your drivetrain protection requires precision-engineered fasteners. The flush-fitting button head design ensures zero interference with your clutch or chain assembly, maintaining a clean, aerodynamic profile while preventing snagging during rapid pit adjustments.

Precision Fitment for Clone and Metric Engines

Designed specifically for engines requiring metric hardware, this bolt kit provides the clamping force necessary to withstand the brutal harmonic vibrations of modern kart engines. Whether you are running a modified 212cc Predator or a spec GX200, the internal locking washers bite into the mounting surface, creating an anti-vibration lock that standard split washers simply cannot match.

• 8mm x 1.25 Metric Threading: Perfectly matched for international and clone engine side-cover mounting points.
• Button Head Cap Screws: Provides a low-profile, flush installation that eliminates clearance issues with moving drivetrain parts.
• Internal Locking Washers: Engineered with aggressive teeth to bite into the metal, preventing back-out from severe engine harmonics.
• High-Tensile Steel Construction: Resists shearing and stretching under extreme thermal and mechanical loads.
• Corrosion-Resistant Finish: Withstands track debris, moisture, and harsh chemical cleaners used in the pits.
• Universal Metric Compatibility: The go-to hardware solution for securing standard and tall chain guards on modern 4-stroke platforms.
• Vibration-Dampening Hold: Maintains consistent torque spec to keep your chain guard rigid, protecting the driver and chassis.

Stop relying on hardware store bolts that put your race weekend at risk. Upgrade to the CGBKM kit and ensure your drivetrain protection is as relentless as your driving.

Frequently Asked Questions

Q: Why should I use button head screws instead of standard hex bolts for my chain guard?

A: Button head screws provide a low-profile, flush installation. This is critical in karting to prevent the bolt heads from snagging on your chain, clutch, or other drivetrain components during high-speed operation or rapid pit adjustments.

Q: Are these bolts compatible with all kart engines?

A: This kit is specifically designed for engines requiring 8mm x 1.25 metric hardware, which is the standard for most modern 4-stroke platforms like the Clone, Predator 212cc, and GX200 engines.

Q: Why are internal locking washers included in this kit?

A: Kart engines produce intense harmonic vibrations that can cause standard hardware to back out. The aggressive teeth on these internal locking washers bite into the mounting surface to maintain consistent torque and prevent the chain guard from loosening during a race.

Q: Can I reuse these bolts after removing the chain guard for maintenance?

A: Yes, the high-tensile steel construction is designed for durability. However, always inspect the locking washers for wear; if the teeth appear flattened or dull, we recommend replacing the washers to ensure a secure, vibration-resistant hold.
