The ECS BB (Ball-Bearing) driveshafts offer a significant performance gain over the standard blade-type driveshafts. The friction between the driveshaft and the outdrive is greatly reduced, which helps to give a much smoother handling feel, especially on fast direction changes, such as chicanes. The reduced friction helps to increase cornering speeds. The 53mm shafts are best suited for more open and flowing track layouts. They will provide slightly less initial steering, but better steering in the middle of the corner, as well as on power.
NOTE: Works only for solid front axle with optional XRA305138 Outdrives.
