New XB4 Composite Slipper Clutch Spur Gears

July 21 (2014

New precision-molded slipper clutch spur gears made from XRAY's exclusive secret blend of composite material, allowing the gear to be robust enough to handle high-performance brushless motors. The spur gears are designed to have the lowest possible weight while staying strong and light. Each gear is stamped with the tooth number for easy identification.

set of 2pcs

Optional rear wings for XB4 & XB4 2WD. The 1.5mm/2.0mm thick material is highly reliable with less chance of breakage, while at the same time influencing the performance of the car as well. The thicker wings give higher traction and stability, but give reduced steering.

New optional linear springs are recommended for high-traction tracks. The springs have been specifically designed to complement the big-bore shocks. Linear spring rate is constant throughout the entire compression.

The springs, like all the other XRAY springs, are manually measured, selected and matched into pairs to guarantee precisely equal length and damping characteristics.
