HB RACING D418 Rear Gear Box - High Grip 

HB-204564 HB RACING D418 Rear Gear Box - High Grip 

This new rear gear box for the HB Racing D418 buggy is designed for high grip astroturf and carpet race tracks. It raises the position of the diff and upper arm mount to match the roll center when using a low ride height. Our HB Team Drivers report it makes the D418 easier to drive on high grip surfaces, improves corner speed, and smoothes out rear end grip. This new rear gear box should be used with D418 Arm Mounts 4, 5 or 6. Comes with one gear box, aluminum tube, R2 skid plate (standard, use with this application), and R4 skid plate (for future options).
