Upgrade Your Viper 990 GP Drivetrain

The Serpent 903811 Lightweight 2-Speed Shaft is engineered for the Viper 990 GP to enhance gearbox behavior. Its lighter construction reduces rotating load and helps maintain steady acceleration while keeping durability in mind.

Performance Gains from Reduced Rotational Load

By cutting rotational mass, the shaft helps the car respond faster to throttle inputs and smooths out gear changes. Club racers and kit tuners will notice improved drivability rather than dramatic power increases.

Compatibility Tips and Quick Fit

This shaft is built to fit the Viper 990 GP assembly directly, offering a hassle-free swap with existing drivetrain parts. Basic mechanical skills and common tools are all you need for installation.
