Shock Length Formula
The following two example problems outline the steps and information needed to calculate the Shock Length.
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
How to Calculate Shock Length?
The following example problems outline how to calculate Shock Length.
Example Problem #1:
- First, determine the distance between the upper shock mount and lower shock mount (in).
- The distance between the upper shock mount and lower shock mount (in) is given as: 6.
- Next, determine the distance between the bump stop and the axle.
- The distance between the bump stop and the axle is provided as: 4.
- Finally, calculate the Shock Length using the equation above:
SHOCK = (D1 – D2) – 1
The values provided above are inserted into the equation below and computed.
SHOCK = (6-4) – 1 = 1 (in)
Example Problem #2:
For this problem, the variables required are provided below:
distance between the upper shock mount and lower shock mount (in) = 3
distance between the bump stop and the axle = 1
Test your knowledge using the equation and check your answer with the calculator..
SHOCK = (D1 – D2) – 1 = ?
