Shock Length Calculator

Formula

To calculate the Shock Length (SHOCK):

\[ SHOCK = (D1 - D2) - 1 \]

Where:

\(SHOCK\) is the shock length (in)
\(D1\) is the distance between the upper shock mount and lower shock mount (in)
\(D2\) is the distance between the bump stop and the axle (in)

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:

Distance between Upper and Lower Shock Mounts (D1) = 20 in
Distance between Bump Stop and Axle (D2) = 5 in

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:

Distance between Upper and Lower Shock Mounts (D1) = 25 in
Distance between Bump Stop and Axle (D2) = 8 in

Using the formula:

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

The Shock Length is 16 inches.
