To fine-tune your vehicle’s suspension system, use following shock length calculator. In the calculator input form enter distance between upper and lower shock mount , distance between bump stop and axle and it will show you recommended length

Shock length is the distance between the mounting points of the shock absorber. This length plays a vital role in maintaining the suspension performance of the vehicle and enabling the shocks to absorb impact.

**Guide: Tool Users**

Input | Action |
---|---|

Distance Upper to Lower Mounts (D1) | Enter distance between shock mounts (e.g., 12 in). |

Distance Bump Stop to Axle (D2) | Enter distance between bump stop and axle (e.g., 4 in). |

Click Calculate | Displays collapsed and extended shock lengths. |

**Input Examples**

Calculation Type | D1 (in) | D2 (in) | Shock Length (SHOCK) (in) |
---|---|---|---|

Basic | 12 | 4 | 7 |

Advanced | 15 | 6 | 8 |

### Formula for Shock Length

Calculate the shock length using:

$\text{SHOCK} = (D1 – D2) –$

Variable | Description |
---|---|

SHOCK | Shock Length (inches) |

D1 | Distance between upper and lower shock mounts (inches) |

D2 | Distance between bump stop and axle (inches) |

**Calculation Example**

Step | Calculation |
---|---|

Distance Upper to Lower (D1) | 12 inches |

Distance Bump Stop to Axle (D2) | 4 inches |

Shock Length Calculation | $(12 – 4) – 1 =$ inches |

**Answer:** The calculated shock length is 7 inches.

## FAQs

**How to Choose the Correct Shock Size**

Choosing the right shock size means measuring the frame of the vehicle at the mount locations and considering what the vehicle will be used for. Use the Shock Length Calculator to find the correct size.

**What Size Shocks Do I Need for a 6 Inch Lift?**

For a 6-inch lift, you’ll need longer shocks to match the extra length. Measure the new distance between the shock mounts after your lift, then use the calculator to find the proper shock length.

**What Shocks Do I Need for a 3-Inch Lift?**

For a 3-inch lift, measure from shock mount to shock mount after the lift. Plug these numbers into the calculator, and it will give you the proper shock size.

Using shock length calculator you surely adjust car shock length. In case you require any kind of additional information regarding this tool you can ask me in the comment section.
