When sourcing premium racing go kart parts to extract every ounce of performance from your go kart engine, the RLV Black Diamond #219 Split Sprocket (89T) delivers unmatched power transfer and rapid adaptability. Manufactured from aerospace-grade 7075-T6 aluminum, this sprocket significantly reduces rotating mass, allowing your engine to spool up faster out of tight corners. The innovative split design means you can execute swift gear ratio modifications without the hassle of removing the axle or breaking the chain, keeping you ahead of evolving race conditions.

Precision Gearing for Maximum Output


To truly capitalize on your briggs and stratton lo206 horsepower, your gearing must be flawless. The 89-tooth configuration is meticulously cut to run true, ensuring optimal chain engagement and reducing the risk of thrown chains during high-load scenarios. RLV's advanced black hard-anodized finish not only provides a sleek, professional look but also increases the sprocket's service life by 25% compared to previous models. This means less wear, lower friction, and more power delivered directly to the track surface.

Seamless Integration with Your Racing Go Kart Frame


Drivetrain alignment is critical, and the Black Diamond sprocket is designed to mount perfectly within any modern racing go kart frame. The split-sprocket architecture is especially beneficial for inboard-drive setups, providing the clearance and ease of access necessary for rapid pit work. By streamlining your workflow, this modular design keeps your pit area organized and cuts crucial prep time between heats.

Beyond Brake Caliper Parts: The Drivetrain Advantage


While many racers focus heavily on upgrading brake caliper parts or aerodynamic fairings, the drivetrain remains the true heart of your kart's performance. Upgrading to the RLV Black Diamond ensures that your momentum is maintained where others falter.

  • 7075-T6 Aluminum Alloy: Aerospace-grade material ensures lightweight durability and minimal rotating mass.
  • Split-Sprocket Architecture: Allows for rapid gear ratio changes without breaking the chain or removing the axle.
  • Black Hard Anodized Finish: Provides a corrosion-proof, low-friction surface for all-weather reliability and extended service life.
  • 89-Tooth Configuration: Ideal for specific track layouts requiring rapid acceleration and precise torque management.
  • #219 Pitch Compatibility: Engineered for seamless, true-running engagement with standard #219 racing chains.
  • Laser-Etched Detailing: Ensures quick tooth-count identification in the pits during high-pressure multi-class events.
  • Gun-Drilled Relief Holes: Strategically placed to reduce weight without compromising structural integrity under heavy loads.

Frequently Asked Questions

Q: Why should I choose a split sprocket over a standard one-piece design?

A: The split design allows you to change your gear ratio quickly at the track without the time-consuming process of removing the rear axle or breaking your chain. This is essential for making rapid adjustments to suit changing track conditions or grip levels.

Q: Is the 89T Black Diamond sprocket compatible with all #219 chains?

A: Yes, this sprocket is precision-engineered for standard #219 pitch racing chains. It ensures smooth engagement and reduces the risk of chain derailment during high-load cornering.

Q: How does the 7075-T6 aluminum construction benefit my kart's performance?

A: Aerospace-grade 7075-T6 aluminum is incredibly lightweight, which reduces rotating mass on the drivetrain. This allows your engine to reach peak RPM faster, resulting in improved acceleration out of tight corners.

Q: How often should I inspect my sprocket for wear?

A: While the hard-anodized finish increases service life by 25%, you should inspect the teeth before every race day. Look for signs of "hooking" or thinning teeth, which indicate the sprocket is nearing the end of its life and could cause chain slippage.

Q: Do I need special tools to install this split sprocket?

A: No special tools are required. Because it is a split design, it bolts directly onto your sprocket carrier. Ensure your mounting hardware is tightened to the manufacturer's recommended torque specifications to prevent vibration or loosening during a race.
