![How to Calculate Spring Rates Without a Scale - Wide Open Design
Trying to figure out the correct spring rates for your buggy or rock crawler? In this video, Adam breaks down a simple method for calculating spring rates at home without:
* corner scales
* suspension software
* complicated geometry math
All you need is:
* your shocks installed
* one pair of springs
* a tape measure
* some simple calculations
We cover:
* spring compression measurements
* supported vehicle weight
* dual-rate spring setups
* crossover adjustment nuts
* ride height calculations
* shock travel setup
* spring stacker charts
Perfect for:
* rock crawlers
* Ultra4 cars
* race bouncers
* Jeeps
* custom tube chassis builds
Formula(s) to get Stacked Spring Rate Chart Number:
1. Spring Length - Compressed Length = X
2. X times Spring Rate = Y
3. Y divided by Inches Collapsed at Ride Height

Timestamps:
Calculating the correct spring rate for your coilovers is one of the most daunting tasks for any builder, but it doesnt have to be. In this masterclass, the Wide Open Design team reveals a failsafe method to determine your rates without ever needing a set of expensive scales [00:51]. We start by installing a single mock-up spring (usually a 150lb rate) to measure the actual weight the shock is supporting [05:56]. By measuring how much that spring compresses under the vehicles weight [07:17], we can calculate the exact poundageâeliminating the need to worry about complex mounting angles or trailing arm leverage [08:02]. We then show you how to use our Spring Stacker Chart to select the perfect secondary spring to achieve your desired ride height and dual-rate performance [09:00]. Stop guessing and start engineering your suspension for the trail.
