The Precision PC219H 1.8MM Link Kart Racing Chain is engineered for high-performance classes such as Senior Rotax, IAME X30 & GX Endurance, where strength, consistency, and efficiency define race results.

With a 1.8 mm reinforced inner and outer link design, this chain delivers exceptional durability and reduced friction  ensuring every ounce of engine power reaches the track.

Built for Higher Torque Applications

Modern senior-class engines produce significantly more torque than earlier junior models.

To handle these extreme loads, the PC219H chain features thicker side plates for enhanced tensile strength and fatigue resistance, reducing stretch under hard acceleration, kerb strikes, and long race distances.

Full Compatibility with Existing Sprockets

Despite its stronger build, the chain retains the standard 219 pitch and roller dimensions, making it fully compatible with all existing 4 mm sprockets.

No sprocket or drivetrain modification is required, just install and go.

Improved Power Delivery & Longevity

The stiffer construction minimizes lateral flex, providing smoother power transfer, more consistent throttle response, and lower elongation rates.

With improved load distribution across sprocket teeth, both chain and sprocket lifespan are extended, even under high-load race conditions.

Minimal Adjustment Required

The reinforced design increases total chain width by less than 1 mm, maintaining full compatibility with standard chain guards and protectors.

We recommend a quick clearance check during initial fitting.
