At H&R product design and development is of the
highest importance. All H&R springs are “cold” wound on specially
designed CNC machinery and then time-tempered to re-align the molecular
structure of the steel to ensure quality and durability. These US Specs springs are in stock ready for shipping
All springs are shot-peened to increase the service life of each spring
by more than 200%. Each spring is then sent through the H&R
exclusive “SuperBlok™” system, which cycles each spring to ensure that
sagging will never occur. Lastly, the H&R special powder coating
process coats each spring with a flexible and durable finish that is
highly resistant to corrosion, chips, and scratches. At H&R we care
about quality –– the whole production process, from start to finish, is
done in-house to ensure the most consistent, highest quality product
possible.
