How to Measure Shocks Before Ordering: A Quick Guide
Ordering shocks without the right measurements is like buying boots without knowing your size—it rarely ends well. This guide will walk you through how to measure your shocks the right way and help you find links to measurement charts from top brands.
Step 1: Know What You're Working With
Start by identifying your current shocks. Removing them from the vehicle makes it easier to measure accurately. Take note of the mount types (stud, loop, bar pin, etc.), which will affect fitment.

Step 2: Take the Key Measurements
You’ll want to measure both the extended and compressed lengths of the shock body. Then subtract the compressed from the extended to find the travel length. Use a measuring tape or ruler, and be precise—half an inch can make a difference.
Step 3: Use Brand-Specific Fitment Charts
Each brand does things a little differently, so using their official guides makes life a lot easier.
