Product Description

Available in 10” and 12” free lengths, QA1 offers an assortment of rates of variable rate springs. With a polished, chrome plated or powder coated, chrome appearing finish, QA1’s variable rate springs are made with the highest quality materials. QA1 springs are strong, consistent, have a long life and lifetime guaranteed to remain within 5% of the original free height under normal operating conditions.

Variable rate springs help compensate for weight changes better than linear rate springs.
An example of how a variable rate spring works:

Linear rate 12 inch spring – 130 lbs. per inch
Every inch of compression adds another 130 lbs.

  • 1” = 130 lbs.
  • 2” = 260 lbs.
  • 3” = 390 lbs.

Variable rate 12 inch spring – 130 /250
In the same amount of travel, the spring rate picks up an additional 90 lbs. of resistance. The spring gets progressively stiffer as it is compressed.

  • 1” = 130 lbs.
  • 2” = 290 lbs.
  • 3” = 480 lbs.

Note: Part #10CS180/600 is polished and chrome plated.
