QA1 offers an assortment of variable rate springs available in 10" and 12" lengths with a silver powder coated finish.
These 2.5" I.D.
variable rate springs are made in the USA with the highest quality materials.
The coil design allows the springs to be compressed to coil-bind without affecting spring rate or free height, along with careful heat-treating and post-processing that greatly improves fatigue life.
These new variable rate springs are ground at both ends for consistent, accurate operations.
All QA1 springs are guaranteed for a lifetime to remain within 2% of the original free height and rate under normal operating conditions.
QA1 springs are manufactured using high-quality materials for strength, consistency, and long life.
Intensive manufacturing processes ensure consistency, accuracy, and durability.
Each QA1 spring is clearly marked with the free length and spring rate for quick identification.
QA1's variable rate springs are proudly made in the USA.
