MIP Twin Hammers X-Duty CVD spline drive kit
Made for Vaterra’s Twin Hammers rock racer is the X-Duty CVD spline drive kit from MIP. The custom involute spline design makes for smooth telescoping operation and thus a more efficient working drivetrain. The kit is a direct replacement for the stock drives and it includes durable steel male and female bones, 5mm drive hubs, cross pins, grub screws and a cup of MIP thread gel and grease.
