The RLV Black Diamond 76T #219 Sprocket delivers uncompromising durability and exact chain alignment for high-torque applications. Built for the grueling demands of competitive sprint racing, this one-piece sprocket is engineered from aerospace-grade 7075-T6 aluminum, providing the ultimate foundation for reliable power delivery session after session.\u003c\/p\u003e\u003ch2\u003eOptimizing Drive-Line Efficiency Beyond Clutch Assembly Upgrades\u003c\/h2\u003e\u003cp\u003eMany drivers focus solely on their engine build, but translating raw output into forward momentum requires a bulletproof drive-line. Whether you are running a high-revving 2-cycle or trying to maximize every ounce of briggs and stratton lo206 horsepower, this 76-tooth sprocket ensures zero energy is wasted. The proprietary Black Diamond hard-anodized coating drastically reduces chain friction, allowing your clutch assembly to engage smoothly and transfer torque instantaneously to the track surface without parasitic drag.\u003c\/p\u003e\u003ch2\u003eConsistent Performance: From Brake Discs to Rear Axle\u003c\/h2\u003e\u003cp\u003eReliability is the cornerstone of any championship-winning chassis setup. Just as you depend on fade-free brake discs to dive deep into the apex, you need a rear sprocket that won't prematurely wear or warp under aggressive acceleration. The RLV Black Diamond series undergoes rigorous metallurgical treatments to withstand extreme temperatures and lateral loads. This means fewer thrown chains, zero mid-race mechanical failures, and a consistent gear mesh that lasts an entire season of hard racing.\u003c\/p\u003e\u003ch2\u003eTrack-Tested Reliability Alongside Your Go Kart Tires\u003c\/h2\u003e\u003cp\u003eYour setup is only as strong as its weakest link. When your fresh go kart tires bite into the asphalt, the sudden shock-load travels directly through your chain and sprocket. The RLV 76T #219 sprocket is purpose-built to handle these violent torque spikes. Its precision-machined tooth profile guarantees that the chain rollers seat perfectly every time, preventing the micro-binding that causes premature wear. Equip your chassis with a sprocket designed for the podium.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e7075-T6 Aerospace Aluminum:\u003c\/strong\u003e Yields exceptional tensile strength to resist bending during aggressive curb strikes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlack Diamond Hard Anodizing:\u003c\/strong\u003e Drastically reduces friction and extends tooth life far beyond standard aluminum sprockets.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision #219 Pitch Profile:\u003c\/strong\u003e Ensures flawless chain engagement, minimizing rolling resistance and parasitic drag.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized 76-Tooth Count:\u003c\/strong\u003e Ideal for dialing in specific gear ratios for medium-to-short sprint tracks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLightweight One-Piece Design:\u003c\/strong\u003e Reduces rotating mass on the axle without sacrificing structural integrity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Heat Dissipation:\u003c\/strong\u003e Maintains dimensional stability even when track temperatures soar during long mains.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUniversal Carrier Fitment:\u003c\/strong\u003e Mounts seamlessly to standard 6-bolt sprocket hubs for quick trackside gear changes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this sprocket compatible with my #35 chain?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No. This is a #219 pitch sprocket.

A 76T sprocket is generally used for medium-to-short sprint tracks. If you find your engine is hitting the rev limiter too early on the straights, you may need a smaller tooth count; if you are lacking acceleration out of corners, you may need a larger tooth count.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this sprocket fit all standard kart axle hubs?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes, this sprocket features a universal 6-bolt pattern designed to mount seamlessly to standard racing kart sprocket carriers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How should I maintain my Black Diamond sprocket?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e After each race day, inspect the teeth for signs of hooking or excessive wear. Clean the sprocket with a degreaser to remove track debris and apply a high-quality chain lubricant to the chain to minimize friction and extend the life of the hard-anodized coating.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why choose 7075-T6 aluminum over steel?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e 7075-T6 aluminum offers an excellent strength-to-weight ratio.
