What is a Shock Length?

The shock length is the effective length of a shock absorber in a vehicle's suspension system. It is calculated by subtracting the distance between the bump stop and the axle from the distance between the upper and lower shock mounts, and then subtracting 1 inch. This measurement is crucial for ensuring proper fit and function of the shock absorber.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ SHOCK = (20 - 5) - 1 = 14 \text{ in} \]

The Shock Length is 14 inches.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ SHOCK = (25 - 8) - 1 = 16 \text{ in} \]

The Shock Length is 16 inches.
