Integrated Activator Plate Viper Big Block Drive Hub 1.0" Bore

Simplify big block integration with the Viper Drive Hub, where the activator plate merges seamlessly into a one-piece unit for 1.0" bores. This design eliminates weak points, ensuring rock-solid lever support under extreme loads.

Black oxide coating shields against rust, ideal for outdoor storage or wet tracks, while the standard pin configuration keeps it versatile for most setups— no big pin variant means focused reliability.

• Integrated plate reduces assembly complexity
• 1.0" bore fits big block cranks perfectly
• Promotes even power distribution for faster shifts
• Coating enhances longevity in harsh environments

In the heat of a race, this hub maintains alignment, preventing slippage that robs speed. For big block warriors, it means harnessing full engine output without drivetrain flex, leading to quicker corner exits.

Builders appreciate the one-piece efficiency— fewer parts to align, more time tuning for peak RPM engagement. It organizes your clutch install, supporting sprockets and weights with precision.

Black oxide not only protects but adds a sleek finish that withstands track grime. Whether upgrading or repairing, this hub elevates drive-line performance, turning potential power loss into straight-line gains.

Compatible with Viper's four-disk systems, it ensures smooth operation across classes. Invest in this for a kart that feels planted and responsive, every lap. The integrated design is a game-changer for stability at speed. SKU: FCDC-DH4T.

Key benefit: no separate lever support means less vibration, directly translating to better handling and reduced maintenance.
