Enter the corner weight (lb) and the unsprung weight (lb) into the Suspension Weight Calculator. The calculator will evaluate the Suspension Weight. 

Suspension Weight Formula

The following two example problems outline the steps and information needed to calculate the Suspension Weight.

SW = CW – UW


  • SW is the Suspension Weight (lb)
  • CW is the corner weight (lb) 
  • UW is the unsprung weight (lb) 

How to Calculate Suspension Weight?

The following steps outline how to calculate the Suspension Weight.

  1. First, determine the corner weight (lb). 
  2. Next, determine the unsprung weight (lb). 
  3. Next, gather the formula from above = SW = CW – UW.
  4. Finally, calculate the Suspension Weight.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

corner weight (lb) = 1,500

unsprung weight (lb) = 500

SW = CW – UW = ?
