Gun Drilled Short Track Axles
THE KERA CONCEPT AND PROPER AXLE SELECTION Although the left and right axles are different lengths, they are typically the same diameter, and therein inherently lies the prob- lem. Because that the right axle is longer, it has a lower spring rate than the left. The result is that left axle does not “wrap-up” as great as the right and the car has a tendency to steer right on LQLWLDODFFHOHUDWLRQEHFDXVHWKHOHIWUHDUVHHVWKHSRZHU¿UVW By simply using a smaller diameter left rear axle with the KERA (“Kleban Equal Response Axles”) split diameter concept (also referred to as wrap axle), torque steer reaction can be equalized under both acceleration and deceleration. By referring to the ac- companying chart, you can determine the proper axle diameter for the right and left side. RECOMMENDED AXLE SET-UPS
