1UP Racing X-Gear 13mm Rear Buggy Pro Pack Springs (4)

The 1UP Racing X-Gear 13mm Rear Buggy Pro Pack Springs were developed with X-Gear Co. of Japan and tested by Professional 1up Factory Drivers in the United States. This pack provides four pairs of springs in different rates for tuning a 1/10 RC buggy across dirt, clay, glued, astroturf, and carpet surfaces.

Features

• Improved grip and traction for a car that feels more “in the track.”
• Smoother handling over bumpy terrain.
• More predictable performance over jumps and landings.
• Trusted by Factory Drivers for personal best runs and track record lap times.
