Trask Performance Sprockets: Precision-Engineered for Chain Drive Power

When Harley-Davidson riders decide to unlock the full potential of their final drive, the sprocket choice matters as much as the conversion kit itself. Trask Performance — the Phoenix-based V-twin specialist sprockets enthusiasts have come to rely on — builds its rear sprockets as an integral part of a larger drivetrain philosophy rather than an afterthought. Founded by Nick Trask, the brand has become synonymous with high-output Harley-Davidson upgrades, and its sprocket lineup is no exception.

Purpose-Built for the Cush Drive Chain Conversion System

Trask's sprockets are engineered specifically to work within their celebrated Cush Drive Chain Conversion ecosystem. Rather than offering generic, one-size-fits-all hardware, these sprockets are designed as direct-fit components for the Trask chain drive system — meaning alignment, carrier interface, and chain engagement are all dialed in from the start.

Trask's chain drive rear sprockets are available in multiple tooth counts — 51, 52, and 54 teeth — giving riders the ability to tune their gearing to match their riding style. As with any final drive setup, tooth count directly influences the power delivery character: a higher tooth count sharpens acceleration and torque feel off the line, while a lower count favors top-end speed on the highway. This flexibility makes Trask sprockets a compelling choice whether you're building a high-powered bagger for long highway runs or a performance-oriented Touring bike that needs snappy throttle response.

Construction Quality That Matches the Performance Pedigree

Trask doesn't cut corners on materials. Their rear sprockets are manufactured from steel and undergo a heat-treatment and coating process specifically designed for long-lasting wear resistance — critical in a chain drive environment where metal-on-metal engagement is constant. This level of metallurgical care reflects the same standards Trask applies across its broader product catalog, from turbo systems to engine components.

The sprockets are designed to mate with Trask's custom billet aluminum cush drive carrier, ensuring proper alignment with factory Touring geometry. The conversion system — and its sprockets — fits 2009 and newer Harley-Davidson Touring models equipped with factory cush-drive setups, and is compatible with both OEM wheels and aftermarket wheels featuring cush-drive hubs. Note that the 52-tooth variant requires an additional adjustment component on 2021 and newer models.

Why Chain Drive — and Why the Sprocket Choice Matters

The case for chain drive over the stock belt final drive is well established in the performance world. A chain-driven system offers meaningfully lower drivetrain transmission loss compared to a belt system, which translates to more of the engine's power actually reaching the rear wheel. For riders running big-power builds — the kind that Trask's turbo kits and engine packages are known to produce — eliminating parasitic loss in the final drive is a logical step. Selecting the correct replacement or upgrade sprocket from Trask ensures that the entire drivetrain system operates as an integrated, precisely matched unit rather than a collection of mismatched parts.

For riders already running a Trask chain conversion, these sprockets also serve as the go-to replacement parts when routine wear makes a swap necessary, or when a change in riding focus calls for a different gear ratio.
